# Which Problems Are Solved
Zitadel did not provide easy correlation between errors, logs, traces
and metrics. The configuration for those instrumentations was also not
consistent, with some supporting different exporters then others.
Implementation and parsing of config was also spaghettified over
multiple packages, with awkward parsing and inconsistent naming of
options.
# How the Problems Are Solved
All telemetry is now merged under the name "instrumentation". Why?
1. We thought it was a good idea in the past to call the milestone
exporter `Telemtry` in the runtime config. Calling this `TelemetryV2`
looks weird.
2. Not everything is a meter and not everything is sent (tele...).
3. It's also
[defined](https://opentelemetry.io/docs/concepts/instrumentation/) as
such by the OTEL documentation.
## New features
- Adds structured, context based logging with trace-ID awareness
- Static log fields are added to the context, such as service and
request path
- Static log fields are injected in each logline emitted by the
application
- Structured logs can also be send to an otel exporter
- Structured logs can be printed to StdErr in text and JSON format
- Error sinks make sure every error is logged at the correct level:
- Warnings for client side errors (HTTP 400 range, Invalid request etc)
- Error for server side errors (Internal server errors)
- Metrics can now also be send to a OTEL collector. (previously they
could only be scraped from `/debug/metrics` with prometheus)
## Exporters
This change adds all the exporters supported by OTEL upstream and some
google specific exporters for our cloud deployment.
- StdOut / StdErr: all instrumentations
- OTEL gRPC / HTTP: all instrumentations
- Google: all instrumentations except logging
- Prometheus (pull-based): only metrics
The exception is profiling, which only supports the google exporting due
to lack of support by OTEL upstream.
## Configuration and structure
- All instrumentation is moved into the new `backend/v3/instrumentation`
package. It reuses configuration types, so both code and runtime
configuration are easier to understand.
- The `internal/telemetry` packages are removed.
- Instrumentation is started with a single function and a proper
shutdown function is now provided.
- Legacy configuration is still parsed from the runtime config, as long
as the new configuration is disabled. This allows backporting this
feature to v4 without breaking existing configurations.
# Additional Changes
- Devcontainer: set `$PATH` variable so installed go binaries can be run
individually, without NX.
- NX: install GCI tool to fix imports

# Which Problems Are Solved

# How the Problems Are Solved
Updated our npm dependencies
# Additional Changes
- Updated Docusaurus to React 19 to unify our react versions
- Fixed flaky e2e test
Closes#11184
# Which Problems Are Solved
- loginName: This information is already retrievable from the URL
parameters during the authentication flow, so logging it presented no
additional exposure.
- idpIntent: This was being logged to the server console (server-side
logs), so it was never exposed to the client/browser.
These changes simply clean up the server logs to prevent unnecessary
data noise.
# How the Problems Are Solved
- Removed idpIntent logging from
`apps/login/src/lib/server/idp-intent.ts`
- Removed loginName logging from
`apps/login/src/lib/server/password.ts`

# Which Problems Are Solved
The application automatically appends the x-zitadel-public-host header
when a public host is configured. In some deployment scenarios where the
host is determined by default or via other means, sending this header
allows for improper routing or is simply redundant. The existing
CUSTOM_REQUEST_HEADERS configuration only supported adding or
overwriting headers, offering no way to remove headers that were set by
default logic.
# How the Problems Are Solved
Extended the `CUSTOM_REQUEST_HEADERS` handling in `src/lib/zitadel.ts`.
The logic now checks for empty header values. If a header is defined in
`CUSTOM_REQUEST_HEADERS` with an empty value (e.g.,
x-zitadel-public-host:), the interceptor will delete that header from
the request instead of setting it to an empty string. This allows users
to opt-out of default headers via configuration.
Closes#11191
# Which Problems Are Solved
This PR fixes the IDP linking for accounts with no authentication
method.
We strictly validate session ownership and generate a hash of the
sessionId + the user's fingerprintId cookie. This hash is passed to the
IDP as linkFingerprint.
This PR addtionally addresses TypeScript errors regarding unknown types
in catch blocks within the IDP intent processing logic. It ensures that
errors occurring during IDP linking are safely handled, and that
meaningful error messages are propagated to the client-side redirect
URLs.
# How the Problems Are Solved
- Safely handle unknown errors: Updated catch blocks in
`processIDPCallback` to check if the caught object is an instance of
Error before accessing error.message.
- Fix "IDP Taken" check: Implemented a safe check for the gRPC error
code 6 (Already Exists) by casting the error, resolving the Property
'code' does not exist on type 'unknown' build error.
- Error Propagation: The specific error message is now passed to the
linking-failed page params, allowing for better user feedback instead of
generic errors.

# Which Problems Are Solved
`IS NULL` and `IS NOT NULL` conditions were incorrectly marked as
restricting columns,
and currently fails unit tests. The restricting columns are mostly used
to ensure single row selection during DELETE and UPDATE . When a `IS NOT
NULL` condition is passed, the filter may (unintentionally) apply to all
rows, while still allowing the query to execute.
Settings and other repositories (still to be done) have unified tables
for instance-level settings and organization-level settings. In those
cases the organization ID may be null or have a value. The unique
condition is a compound of multiple columns, in which case `IS NULL` is
valid as part of the other restricting columns.
# How the Problems Are Solved
In order to prevent unsafe usage of null related filters and not break
settings:
- null conditions are no longer considered restricting columns
- A function to force the restricting column state on a condition is
provided
- The settings unique condition function forces restricting column state
on the returned condition.

# Which Problems Are Solved
When users accessed the login page without an organization context and
entered a login name with a domain suffix (e.g., [[email protected]], the
system would return "user not found" instead of performing organization
discovery.
# How the Problems Are Solved
Added organization discovery logic that triggers after a global user
search returns no results. When no organization context is provided:
- Extracts the domain suffix from the loginName (e.g., @company.com)
- Queries for organizations with that domain as their primary domain
- If exactly one organization is found with allowDomainDiscovery
enabled, uses it as the discovered organization
- Redirects users to the appropriate flow (IDP, registration, or
password) with the discovered organization context

# Which Problems Are Solved
When users authenticate via IDP (Identity Provider) without explicit
organization context, the flow could fail or create users without proper
organization assignment. This occurred when:
- No organization parameter was provided in the IDP callback
- Domain discovery didn't find a matching organization
- OIDC requests didn't include organization scopes
# How the Problems Are Solved
Implemented a fallback mechanism that ensures organization context is
always available:
- Centralized organization resolution in `resolveOrganizationForUser()`
- First: Use explicitly provided organization
- Second: Attempt domain discovery from username
- Third: Fallback to default organization (NEW)
- Explicit error handling: Users are never created without organization
context. If no organization can be determined (including no default
org), the flow fails gracefully with a clear error message.
- Applied to both creation flows:
- CASE 4: Auto-creation of users
- CASE 5: Manual user registration

# Which Problems Are Solved
An IDP Intent could not be completed due to a missing change of
successUrl property in a recent PR.
# How the Problems Are Solved
The /success page has been replaced by /process to finish the IDP flow
in all occurences.
# Which Problems Are Solved
The passkey login page was not rendering properly in production (Cloud
Run) deployments, with the submit button and component content not
appearing. Additionally, the automatic passkey prompt was not triggering
correctly.
# How the Problems Are Solved
Added the missing return statement before navigator.credentials.get() in
the submitLoginAndContinue function. This ensures the promise is
properly returned and chained in the useEffect hook, fixing the
automatic passkey prompt flow.
Removes the recently introduces guides to passkeys that could result in
a hydration error due to the <a> tag being rendered differently on
server / client environement
# Additional Changes
This issue was most probably introduced in PR #10971. The component uses
promise chaining (.then().catch().finally()) which requires the promise
to be returned, unlike the RegisterPasskey component which uses
async/await and works correctly without an explicit return.
# Which Problems Are Solved
This PR enhances the passkey authentication flow with comprehensive
error handling, full internationalization support, and extensive test
coverage.
# How the Problems Are Solved
I18n:
- Replaced all hard-coded error messages with i18n translation keys
- Consistent error messaging throughout the passkey flow
- Added specific error handling for passkey cancellation
(NotAllowedError)
- Implemented fallback errors for undefined/missing responses
- Better error messages for:
- Session retrieval failures
- Challenge request failures
- User verification errors
- Redirect determination issues
Tests:
- Added `login-passkey.test.tsx` with 100+ test cases covering:
- Successful verification flows
- Error scenarios and edge cases
- Props handling
- Component lifecycle
- Added passkeys.test.ts with server-side function tests:
- Session cookie retrieval
- User validation
- Custom lifetime handling
- Critical fallback error paths
Try-catch blocks around critical user retrieval operations
Defensive checks for undefined responses from completeFlowOrGetUrl
Support for custom lifetime parameters
Cleaner error propagation
Closes#10828
# Which Problems Are Solved
The IDP callback flow was calling retrieveIDPIntent() twice, causing
single-use token failures with error: "Intent Token is invalid". This
occurred due to Next.js 15's dynamicIO feature triggering double renders
# How the Problems Are Solved
Completely refactored the IDP callback architecture to ensure single-use
tokens are consumed exactly once:
- Centralized Business Logic: Moved all IDP callback logic into a single
server action (processIDPCallback) that:
- Consumes the token once
- Handles all 6 business scenarios (login, linking, auto-linking,
auto-creation, manual registration, account not found)
- Integrates session creation in the same action
- Returns `{ redirect?: string; error?: string }` for client-side
navigation
- Client Component Invocation: Created `IdpProcessHandler` client
component that:
- Calls the server action from browser context (enables cookie
modification)
- Prevents double execution with useRef
- Handles loading states and error display
- Clean Architecture:
- Removed 403-line success page with complex logic
- Removed component files from `/components/idps/pages/` folder
- Moved all UI directly into server pages
- Created dedicated result pages with minimal params
# Additional Changes
- Added translations to all 8 supported languages

# Which Problems Are Solved
When the passkey registration page (/passkey/set) is accessed externally
with only a loginName parameter, users encounter a "Missing code in
response" error. This occurs because the registration code is only
generated for invalid sessions, but external calls typically have valid
sessions.
# How the Problems Are Solved
- Moved registration code generation outside the session validity check
in `registerPasskeyLink()`
- Code is now generated for both valid and invalid sessions when not
provided
- Simplified logic: use provided code if available, otherwise generate a
new one
Add complete Turkish (tr.json) translation for authentication UI,
including login, registration, password management, MFA setup
# Which Problems Are Solved
- Turkish language support is missing in the authentication UI
- Turkish-speaking users cannot use the application in their native

# How the Problems Are Solved
- Added complete Turkish (tr.json) translation file for the
authentication UI
- Translated all authentication-related strings including login,
registration, password management, MFA setup, error messages, and user
verification flows
- Technical terms (Passkey, SSO, LDAP, IDP, etc.) are kept in English
for consistency
# Additional Changes
- None
# Additional Context
- Closes#10851

# Which Problems Are Solved
In the login we often check if a GRPC Duration is not defined however it
can also be set to 0. Using the API it's possible to set the password
check lifetime to zero which broke the login v2.

# Which Problems Are Solved
This PR makes sure that the tarballs containing the API binary and the
standalone login are separately downloadable from the release pages
again.
# How the Problems Are Solved
Because the `Pack` workflow uploads a single GitHub artifact containing
all tarballs since #10571, we download this artifact so that it
correctly unpacks into the correct folder structure configured in
`.releaserc.js`
The changes are tested [with this action
run](https://github.com/eliobischof/zitadel/actions/runs/18745783976),
which [created this
release](https://github.com/eliobischof/zitadel/releases/tag/v1.0.0-release-archives.5).
# Additional Changes
- The term `standalone` is removed from the login tarball, as it should
be clear that it is a standalone build.
- The go builds and the login archiving are less verbose
- The pipelines go versions are pinned to *v1.25*, a minor above the
minimally required go version *v1.24.0* described in the go.mod file.
This makes sure that we build using newer patches for security and
performance.
# Additional Context
- The archives weren't published anymore since #10571

# Which Problems Are Solved
When a user with no authentication methods attempted to log in, the
system always set `invite=true` in the verification flow, regardless of
whether their email was already verified. This could cause errors when
trying to send invite codes to already initialized users.
# How the Problems Are Solved
Added conditional logic to determine whether to send an invite code
based on the user's email verification status:
This prevents errors when attempting to send invite codes to users who
have already verified their email and been initialized, while still
properly handling new users who need invitation flows.
Closes#10671
# Which Problems Are Solved
Users with password authentication disabled in their organization were
seeing "Username Password not allowed!" error instead of being
redirected to their organization's configured Identity Provider. This
affected domain discovery and multi-tenancy use cases in Login V2.
# How the Problems Are Solved
- Updated `redirectUserToIDP` to accept optional `userId` and
`organization` parameters
- Added fallback logic to check organization-level IDPs via
`getActiveIdentityProviders`
- Updated all call sites to pass appropriate organization context
- Added test coverage for the fallback behavior
# Additional Changes
- Consolidated duplicate logic by removing
`redirectUserToSingleIDPIfAvailable` function, which is now handled by
the unified `redirectUserToIDP` function
- improved error handling on verification page

This PR fixes an issue in the IDP auto-linking feature where user
searches were performed globally instead of being scoped to the current
organization context. This could result in IDP links being created for
users in unintended organizations.
# Which Problems Are Solved
When IDP auto-linking was enabled (by email or username), the system
would search for existing users across all organizations instead of
restricting the search to the current organization context.
# How the Problems Are Solved
Added organization scoping to all three auto-linking code paths

# Which Problems Are Solved
- Japanese users cannot use the Login UI in their native language, as
only other locales (English, German, Italian, Spanish, Polish, Chinese,
Russian, Turkish) are currently supported
- The Login UI language selection does not include Japanese as an option
# How the Problems Are Solved
- Updated the `LANGS` array in `apps/login/src/lib/i18n.ts` to include
Japanese (`{ name: "日本語", code: "ja" }`)
- Enables Japanese language selection in the Login UI through browser
language detection or manual locale setting
# Additional Changes
- No additional changes were necessary as other components (Console,
email notifications, common messages, Go templates) already have
Japanese locale support (`ja.json`/`ja.yaml` files exist)
# Additional Context
- This contribution enhances ZITADEL's internationalization support for
Japanese-speaking users
- The translation follows the same structure and key naming conventions
as existing locale files
- Testing can be performed by setting browser language to Japanese or
using `NEXT_LOCALE=ja` cookie

# Which Problems Are Solved
Improves the user experience when IDP authentication succeeds but user
creation/linking fails by introducing a `postErrorRedirectUrl` parameter
and dedicated error pages instead of generic error screens.
<img width="580" height="636" alt="Screenshot 2025-10-16 at 09 21 07"
src="https://github.com/user-attachments/assets/db653c8f-b648-4cfe-922a-2f237f3b70b3"
/>
# How the Problems Are Solved
## New Pages
- **`/idp/[provider]/account-not-found`**: Displayed when no user
account exists and creation/linking is not allowed
- **`/idp/[provider]/registration-failed`**: Displayed when user
registration fails due to organization resolution issues
## Flow Improvements
- Added `postErrorRedirectUrl` parameter to track where the IDP flow was
initiated
- Each entry point (loginname, register, idp, authenticator/set)
specifies its own redirect URL
- Users are now redirected to appropriate error pages with clear
messaging instead of generic error screens
- All context (`requestId`, `organization`, `postErrorRedirectUrl`) is
preserved throughout the flow
## Updated Components
- `SignInWithIdp`: Now accepts and passes `postErrorRedirectUrl`
parameter
- `redirectToIdp` server action: Extracts and forwards
`postErrorRedirectUrl` through the IDP flow
- IDP success page: Routes to appropriate error pages based on failure
reason
## i18n
Added new translation keys:
- `idp.accountNotFound.*` - For missing account scenarios
- `idp.registrationFailed.*` - For organization resolution failures
# Which Problems Are Solved
This change shows the default titles for password pages instead of
dynamically showing the user name.
# How the Problems Are Solved
Both pages now show only the translated title text (verify.title and
change.title respectively) instead of falling back to showing the user's
display name.

# Which Problems Are Solved
The newest release (v4.3.2) was not serving the `zitadel.css` for the
login anymore. The previous file was served from cache, making it not
directly visible.
The problem was caused due to the CI change (#10571) where the generate
was moved from a makefile to Nx commands, which run in parallel.
Depending on timing, the generated css file might be embedded into the
login or not.
# How the Problems Are Solved
- Configure the commands to run sequentially.
# Additional Changes
none
# Additional Context
- relates to #10571
- requires backport to v4.x
# Which Problems Are Solved
By default, the login redirects in all cases from its
`NEXT_PUBLIC_BASE_PATH` to `NEXT_PUBLIC_BASE_PATH/loginname` now. This
is the expected behavior.
# How the Problems Are Solved
Deployments to Vercel use the `apps/login/.env` file for their defaults.
As the .env file had DEBUG=true, redirects from root to ./loginname were
disabled.
DEBUG=true is not needed anywhere, so it's deleted from the .env file.
# Which Problems Are Solved
The new pipeline did not correctly build the release. Console was not
built into the binary. Also there were some pipeline permission errors.
# How the Problems Are Solved
- add `build-console` as dependency to pack binaries
- streamline permissions and only pass necessary into steps

# Which Problems Are Solved
When Postgres was not ready when the API was started, the API failed
immediately.
This made task orchestration hard, especially in a platform agnostic
way:
- The current health check in the Nx target `@zitadel/api:prod` uses the
timeout command, which is not installed on all platforms and behaves
unpredictably
- The current health check in the Nx target `@zitadel/api:prod` requires
the DB to have been started using `@zitadel/zitadel:db`
# How the Problems Are Solved
- Additional configuration option `Database.Postgres.AwaitInitialConn`
is added and defaults to *0m* for backwards compatibility.
- If a duration is configured, the API retries to ping the database
until it succeeds
- The API sleeps for a second between each ping.
- It emits an info-level log with the error on each try.
- When the configured duration times out before the ping is successful,
the error is returned and the command exits with a failure code.
- When the ping succeeds within the configured duration, the API goes on
with the init, setup or start phase.
# Additional Context
- Relates to internally reported problems with the current DB health
check command

Replaces Turbo by Nx and lays the foundation for the next CI
improvements. It enables using Nx Cloud to speed the up the pipelines
that affect any node package.
It streamlines the dev experience for frontend and backend developers by
providing the following commands:
| Task | Command | Notes |
|------|---------|--------|
| **Production** | `nx run PROJECT:prod` | Production server |
| **Develop** | `nx run PROJECT:dev` | Hot reloading development server
|
| **Test** | `nx run PROJECT:test` | Run all tests |
| **Lint** | `nx run PROJECT:lint` | Check code style |
| **Lint Fix** | `nx run PROJECT:lint-fix` | Auto-fix style issues |
The following values can be used for PROJECT:
- @zitadel/zitadel (root commands)
- @zitadel/api,
- @zitadel/login,
- @zitadel/console,
- @zitadel/docs,
- @zitadel/client
- @zitadel/proto
The project names and folders are streamlined:
| Old Folder | New Folder |
| --- | --- |
| ./e2e | ./tests/functional-ui |
| ./load-test | ./benchmark |
| ./build/zitadel | ./apps/api |
| ./console | ./apps/console (postponed so the PR is reviewable) |
Also, all references to the TypeScript repo are removed so we can
archive it.
# How the Problems Are Solved
- Ran `npx nx@latest init`
- Replaced all turbo.json by project.json and fixed the target configs
- Removed Turbo dependency
- All JavaScript related code affected by a PRs changes is
quality-checked using the `nx affected` command
- We move PR checks that are runnable using Nx into the `check`
workflow. For workflows where we don't use Nx, yet, we restore
previously built dependency artifacts from Nx.
- We only use a single and easy to understand dev container
- The CONTRIBUTING.md is streamlined
- The setup with a generated client pat is orchestrated with Nx
- Everything related to the TypeScript repo is updated or removed. A
**Deploy with Vercel** button is added to the docs and the
CONTRIBUTING.md.
# Additional Changes
- NPM package names have a consistent pattern.
- Docker bake is removed. The login container is built and released like
the core container.
- The integration tests build the login container before running, so
they don't rely on the login container action anymore. This fixes
consistently failing checks on PRs from forks.
- The docs build in GitHub actions is removed, as we already build on
Vercel.

Closes#10671
# Which Problems Are Solved
Users with only password authentication method were immediately shown an
error "Username Password not allowed" when
`loginSettings.allowUsernamePassword` was set to false. However, the IDP
flow could potentially allow the user to register a new account or link
an existing account, providing a better user experience than a dead-end
error.
# How the Problems Are Solved
- Modified single password method case to attempt IDP redirect before
showing error
- This allows users to potentially register or link accounts through the
IDP flow instead of hitting an immediate error
- Only show error as last resort when no IDP alternative is available
# Which Problems Are Solved
Add projects to the relational tables
# How the Problems Are Solved
- Define table migrations
- Define and implement Project and Project Role repositories.
- Provide projection handlers to populate the relational tables.
# Additional Changes
- Statement Builder now has a constructor which allows setting of a base
query with arguments.
- Certain operations, like Get, Update and Delete require the Primary
Key to be set as conditions. However, this requires knowledge of the
implementation and table definition. This PR proposes an additional
condition for repositories: `PrimaryKeyCondition`. This gives clarity on
the required IDs for these operations.
- Added couple of helpers to the repository package, to allow more DRY
code.
- getOne / getMany: generic functions for query execution and scanning.
- checkRestrictingColumns, checkPkCondition: simplify condition
checking, instead of using ladders of conditionals.
- Added a couple of helpers to the repository test package:
- Transaction, savepoint and rollback helpers.
- Create instance and organization helpers for objects that depend on
them (like projects).
# Additional Context

- closes#10765
Closes#10727Closes#10577
# Which Problems Are Solved
This PR fixes the organization domain scope when provided and introduces
a deep-link feature for external applications, that sends users directly
into passkey registration flow using either session-based or sessionless
flows. Previously, the `/passkey/set` page only supported session-based
registration, limiting external application integration scenarios.
The `/passkey/set` page now supports:
- `code` search parameter for automatic passkey registration
- `userId` parameter for sessionless flows (similar to `/verify` and
`/password/set` pages)
- Auto-submit functionality when verification codes are provided
# How the Problems Are Solved
The organization scope is fixed by the backend handler for OIDC flows,
now correctly submitting a `suffix` queryparam to the /loginname url
which is used to show in the input field.
The passkey code support is implemented by support multiple integration
patterns:
- **Session-based**: `/passkey/set?sessionId=123&code=abc123` (existing
flow)
- **Sessionless**: `/passkey/set?userId=123456&code=abc123` (new flow)
External Application Integration Flow
1. External app triggers passkey register and obtains code
2. User verification link containing `userId`, `code` and `id`
parameters
3. User clicks link → `/passkey/set?userId=123&code=abc&id=123`
4. Page loads user information using `userId` parameter
5. Auto-submit triggers passkey registration when `code` and `id` is
present
6. User completes WebAuthn request
7. Passkey is registered and user continues authentication flow
This enables external applications to seamlessly integrate passkey
registration into their user onboarding

# Which Problems Are Solved
When deploying the login application behind proxies or using Vercel
rewrites (e.g., `zitadel.com/login` → `login-zitadel-qa.vercel.app`),
the application was using the internal rewritten host instead of the
original user-facing host. This caused several issues:
1. **Broken Password Reset Emails**: Email links contained internal
hosts like `login-zitadel-qa.vercel.app` instead of `zitadel.com`
2. **Inconsistent User Experience**: Users would see different domains
in various parts of the flow
3. **Security Concerns**: Internal infrastructure details were exposed
to end users
4. **Scattered Logic**: Host detection logic was duplicated across
multiple files with inconsistent error handling
# How the Problems Are Solved
Created comprehensive host detection utilities in `/lib/server/host.ts`
and `/lib/client/host.ts`:
**Server-side utilities:**
- `getOriginalHost()` - Returns the original user-facing host
- `getOriginalHostWithProtocol()` - Returns host with proper protocol
(http/https)
The /login route was experiencing issues with React Server Component
(RSC) requests interfering with one-time authentication callbacks. When
users navigated to /login via client-side routing (router.push()),
Next.js automatically triggered _rsc requests that could consume
single-use createCallback tokens, breaking OIDC and SAML authentication
flows.
# Which Problems Are Solved
When users attempt to log in, Next.js automatically makes requests with
the `_rsc=1` query parameter for React Server Components. The current
implementation treats these as server errors:
```typescript
// Before
if (_rsc) {
return NextResponse.json({ error: "No _rsc supported" }, { status: 500 });
}
```
This results in:
- Spurious 500 error logs polluting monitoring systems
- False alerts for server failures
- Difficulty distinguishing real issues from benign RSC requests
# How the Problems Are Solved
This PR implements a comprehensive refactoring that:
- Eliminates RSC interference by providing server actions for internal
auth flow completion
- Separates concerns between external flow initiation and internal flow
completion
- Extracts shared utilities to improve code maintainability and
reusability
- Maintains full backward compatibility for external applications
# Additional Context
## New Architecture
- auth-flow.ts: Shared utilities for auth flow completion with RSC
protection
- flow-initiation.ts: Extracted OIDC/SAML flow initiation logic (~400
lines)
- auth.ts: Server actions for internal components
## Route Handler Simplification
- route.ts: Reduced from ~350 lines to ~75 lines
- External-only focus: Now handles only flow initiation for external
applications
- Removed completion logic: External apps use their own callback URLs
- Enhanced validation: Early RSC blocking and parameter validation
## Flow Logic Improvements
- Early return patterns: Guard clauses eliminate deep nesting
- Better error handling: Specific error messages for different failure
modes
- Fixed SAML flow: Addressed incomplete logic
- Consistent session handling: Unified approach across OIDC and SAML
This PR completely removes Next.js image optimization from the login app
by replacing all next/image components with standard HTML <img> tags and
removing the image optimization configuration.
Closes https://github.com/zitadel/zitadel-charts/issues/381
# Which Problems Are Solved
Users were encountering issue when loading images in dedicated
environments. These happened due to nextjs imaging optimizations
creating different paths for images.
# How the Problems Are Solved
- Removed Next.js Image Optimization Config
- Removed images: { unoptimized: true } configuration from
[next.config.mjs](vscode-file://vscode-app/Applications/Visual%20Studio%20Code.app/Contents/Resources/app/out/vs/code/electron-browser/workbench/workbench.html)
This config was redundant since we no longer use next/image components
- Replaced next/image with standard <img> tags
Safari was not creating session cookies during local development,
causing authentication failures. This was due to nextjs default setting
of SameSite cookie property.
We explicitly set "strict" for session cookies now.
Closes#10473
# Which Problems Are Solved
Authentication Issues with Safari in local development
# How the Problems Are Solved
- Cleaner API: Replaced confusing sameSite boolean/string parameters
with iFrameEnabled boolean
- Better logic flow:
iFrameEnabled: true → sameSite: "none" (for iframe embedding)
Production → sameSite: "strict" (maximum security)
This PR removes the Vercel Analytics integration from the login
application to reduce external dependencies and improve privacy.
# Which Problems Are Solved

# How the Problems Are Solved
- Removed dependency: Uninstalled @vercel/analytics package from
package.json
- Updated layout component: Removed Analytics import and component usage
from layout.tsx
- Updated Content Security Policy: Removed Vercel domains
(https://va.vercel-scripts.com and https://vercel.com) from CSP
configuration in csp.js
