# 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

# 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.

/>
# 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

# How the Problems Are Solved
Replace this example text with a concise list of changes that this PR
introduces.
For example:
- adds i18n for password complexity requirements
- adds i18n for password, loginname, register and verify components

Closes#10498
The registration form's legal checkboxes had incorrect validation logic
that prevented users from completing registration when only one legal
document (ToS or Privacy Policy) was configured, or when no legal
documents were required.
additionally removes a duplicate description for "or use Identity
Provider"
# Which Problems Are Solved
Having only partial legal documents was blocking users to register. The
logic now conditionally renders checkboxes and checks if all provided
documents are accepted.
# How the Problems Are Solved
- Fixed checkbox validation: Now properly validates based on which legal
documents are actually available
- acceptance logic: Only requires acceptance of checkboxes that are
shown
- No legal docs support: Users can proceed when no legal documents are
configured
- Proper state management: Fixed checkbox state tracking and mixed-up
test IDs

# Which Problems Are Solved
- Most inputs have hardcoded label
# How the Problems Are Solved
- add usage of i18n library for every label
- add labels to i18n translation files
# Additional Changes
- fixed key used in `device-code-form.tsx` by submit button
- `v2-default.json` was update and contains all values from login app
not only newly added key for labels.

# Which Problems Are Solved
- The previous monorepo in monorepo structure for the login app and its
related packages was fragmented, complicated and buggy.
- The process for building and testing the login container was
inconsistent between local development and CI.
- Lack of clear documentation as well as easy and reliable ways for
non-frontend developers to reproduce and fix failing PR checks locally.
# How the Problems Are Solved
- Consolidated the login app and its related npm packages by moving the
main package to `apps/login/apps/login` and merging
`apps/login/packages/integration` and `apps/login/packages/acceptance`
into the main `apps/login` package.
- Migrated from Docker Compose-based test setups to dev container-based
setups, adding support for multiple dev container configurations:
- `.devcontainer/base`
- `.devcontainer/turbo-lint-unit`
- `.devcontainer/turbo-lint-unit-debug`
- `.devcontainer/login-integration`
- `.devcontainer/login-integration-debug`
- Added npm scripts to run the new dev container setups, enabling exact
reproduction of GitHub PR checks locally, and updated the pipeline to
use these containers.
- Cleaned up Dockerfiles and docker-bake.hcl files to only build the
production image for the login app.
- Cleaned up compose files to focus on dev environments in dev
containers.
- Updated `CONTRIBUTING.md` with guidance on running and debugging PR
checks locally using the new dev container approach.
- Introduced separate Dockerfiles for the login app to distinguish
between using published client packages and building clients from local
protos.
- Ensured the login container is always built in the pipeline for use in
integration and acceptance tests.
- Updated Makefile and GitHub Actions workflows to use
`--frozen-lockfile` for installing pnpm packages, ensuring reproducible
installs.
- Disabled GitHub release creation by the changeset action.
- Refactored the `/build` directory structure for clarity and
maintainability.
- Added a `clean` command to `docks/package.json`.
- Experimentally added `knip` to the `zitadel-client` package for
improved linting of dependencies and exports.
# Additional Changes
- Fixed Makefile commands for consistency and reliability.
- Improved the structure and clarity of the `/build` directory to
support seamless integration of the login build.
- Enhanced documentation and developer experience for running and
debugging CI checks locally.
# Additional Context
- See updated `CONTRIBUTING.md` for new local development and debugging
instructions.
- These changes are a prerequisite for further improvements to the CI
pipeline and local development workflow.
- Closes#10276
