# Which Problems Are Solved
- Native iOS/Android passkeys need OS trust files on the ZITADEL domain;
without them, Associated Domains / App Links verification fails.
- Operators could not configure iOS Team ID + Bundle ID or Android
package name + SHA-256 fingerprints on OIDC apps.
- `/.well-known/apple-app-site-association` and
`/.well-known/assetlinks.json` were not served from application config.
# How the Problems Are Solved
- Add iOS/Android app-link fields on OIDC app create/update (Application
API v2 + Management), with validation.
- Persist and project those fields; query active app-link configs
instance-wide.
- Serve AASA (`webcredentials`) and Digital Asset Links
(`get_login_creds`) from well-known paths, with configurable
`Cache-Control` and fingerprint normalization at serve time.
- Console UI to edit the fields, with links to the well-known endpoints.
- Operator docs for configuration, endpoints, caching, and verification.
# Additional Changes
- Document on API fields that well-known responses may be HTTP-cached
and platform verifiers may delay propagation.
- Runtime config: `WellKnown.AppLinksCacheControlMaxAge` (default `5m`;
`0` → `no-store`).
# Additional Context
- Closes#12497
- Implemented and reviewed as stack:
- #12531 API contract
- #12532 storage wiring
- #12536 well-known endpoints
- #12537 console
- #12547 docs

# Which Problems Are Solved
ZITADEL cannot currently be used as an OAuth 2.0 Authorization Server by
clients that need to register themselves at runtime:
- There is no [OAuth 2.0 Dynamic Client Registration (RFC
7591)](https://datatracker.ietf.org/doc/html/rfc7591) endpoint, and no
`registration_endpoint` is advertised in the discovery document.
- This blocks [Model Context Protocol
(MCP)](https://modelcontextprotocol.io) clients (Claude Desktop,
claude.ai, Cursor, the MCP SDKs), whose OAuth 2.1 authorization profile
expects an Authorization Server that supports dynamic client
registration. They self-register before any user context exists and only
then start the authorization code + PKCE flow.
# How the Problems Are Solved
## Control plane: instance security settings
No feature flag and no runtime config. A
`DynamicClientRegistrationSettings` message is nested under the instance
`SecuritySettings` in `settings/v2`, next to `embedded_iframe` and
`enable_impersonation`:
| `enabled` | `allow_unauthenticated` | Behaviour |
| --- | --- | --- |
| `false` (default) | — | `POST /oauth/v2/register` returns `404`,
`registration_endpoint` absent from discovery |
| `true` | `false` (default) | Token-gated registration, client homed in
the token's organization |
| `true` | `true` | Open registration for MCP hosts, client homed in the
instance default organization |
Both values are carried on `authz.Instance` and loaded with the
instance, exactly like `EnableImpersonation`, so the discovery document
and the endpoint read them per request without an extra query.
`allow_unauthenticated` implies `enabled` in both implementations, so a
single setting closes the endpoint.
Adding the two columns bumps the projection table to
`projections.security_policies3`, following what the impersonation
setting did for `security_policies2`.
## Authorization: a dedicated permission, not `project.app.write`
- New org-scoped permission **`project.app.register_dynamic`**, granted
by default to `ORG_OWNER`, `IAM_OWNER` and `IAM_ORG_MANAGER` — in both
`InternalAuthZ` and `SystemAuthZ`, mirroring where `project.app.write`
already lives.
- New built-in role **`ORG_DYNAMIC_CLIENT_REGISTRAR`** carrying only
that permission, so a service user can self-register clients without
gaining write access to the organization's existing applications.
- Open mode (`allow_unauthenticated = true`) requires no token and no
permission: that is the MCP self-register path.
- A valid token whose user lacks the permission is answered with **`403
insufficient_scope`** (RFC 6750 §3.1) rather than `401 invalid_token`,
so a caller can tell "your token is bad" from "your token may not do
this". `verifyAccessToken` also reports invalid tokens as permission
denied, so the authorization failure is marked explicitly to keep the
two apart.
The check runs once, at the endpoint, right after the token is verified
and before any state is created, so it also gates the auto-provisioning
of the organization's DCR project. The permission itself lives in the
command layer next to the others
(`Commands.CheckPermissionRegisterDynamicClient`). As the OIDC endpoints
are not behind the authorization interceptor, the caller identity is
derived from the verified token, the way token exchange does for the
impersonating actor.
## Registration itself
- **Registered clients are ordinary OIDC applications.** The endpoint
reuses the existing application-creation events
(`NewApplicationAddedEvent` and `NewOIDCConfigAddedEvent`), so the whole
token, authorization and introspection flow keeps working unchanged.
They are stored in a dedicated, auto-provisioned project named `ZITADEL
DCR` per organization (name lookup), so they do not pollute the
`IAMProject` or other projects.
- Input is validated with the existing `GetOIDCV1Compliance` rules;
`private_key_jwt` and `jwks`/`jwks_uri` are rejected with
`invalid_client_metadata`.
- **Endpoint wiring without forking the library.** `NewServer` calls
`op.RegisterServer` instead of `op.RegisterLegacyServer`, so the new
route can be added through the same `op.WithSetRouter` hook as the
authorize callback. `op.RegisterLegacyServer` appends a middleware after
the caller options, which chi forbids once a route has been registered;
`op.NewIssuerInterceptor` reproduces the issuer middleware it would
otherwise add. The `/oauth/v2` routing prefix is unchanged.
# Additional Changes
- **`application_type` inference for custom-scheme redirects** (last
commit, isolated). `application_type` is an OpenID Connect member; RFC
7591 does not define it, so clients that only implement RFC 7591 omit
it. Native MCP hosts doing so register custom-scheme redirect URIs,
which ZITADEL reserves for native applications, and the OIDC default of
`web` rejected them with `invalid_redirect_uri`. Inference is limited to
custom schemes and to an absent `application_type`, so every request
accepted today keeps its current application type and auth method — an
`http` loopback redirect still yields a web application. Happy to drop
this commit if you would rather keep it out of this PR.
- **Docs**: a Dynamic Client Registration integration guide, a
`registration_endpoint` section on the OpenID Connect endpoints page,
and the new role in the administrators table (plus its description in
the Console translations).
# Additional Context
- Part of #9810. This is **Phase 1 (DCR)**; #12315 adds RFC 7592 and
#12316 adds CIMD, both stacked on this branch and rebased once this
lands.
- Implements the control-plane and authorization model requested in the
review of this PR, itself a refinement of the direction in
https://github.com/zitadel/zitadel/issues/9810#issuecomment-4891176997.
- **Out of scope (deliberately)**: RFC 7592, CIMD, persisting free-form
metadata (`logo_uri`, `contacts`, and similar), and `private_key_jwt` /
`jwks_uri` (rejected cleanly). No new event types.
- Follow-ups explicitly left out, per the review: DCR client lifecycle
and richer audit, consent and custom scopes, JWT / `aud` (RFC 8707), and
RFC 8414 AS metadata (currently absent from both ZITADEL and
`zitadel/oidc`).
# Which Problems Are Solved
Zitadel exposes the secrets generator configuration through its admin
api. This allows instance admins to manage them on their own and they
can create overwrite the system / runtime defaults (incl. expiration).
This very much needed in multi-instance scenarios such as zitadel.cloud.
Currently the invite code configuration was not manageable through the
API, but only runtime config.
# How the Problems Are Solved
- added the `invite_code` type to the API allowing it to be set and
retrieved.
- added the type to console's management list
- added the type to be stored on instance setup
- change the `GetSecretGenerator` endpoint to fall back to the runtime
config if no config is stored on the instance itself
- ensure the `length` and at least one charset is enabled, return an
error otherwise
- expiry is not enforced, so 0 allows codes with no expiry (current
state)

# Which Problems Are Solved
The payload in actions V2 is currently sent as JSON to the target
endpoint. It might get exposed to intermediary infrastructure or logging
systems.
For these scenarios there needs to be an application-layer encryption,
where the provider of the endpoint can define an key to be used for the
encryption.
# How the Problems Are Solved
- Added an additional option to the target to specify the payload type:
`JSON` (current and default), `JWT`, `JWE` (api and console)
- added endpoints to upload and manage public keys (to be used for
encryption) for a target
- updated all action v2 executions (interceptors, oidc, saml, ...) to
provide the `GetActiveSigningWebKey` from queries
- implemented jwt and jwe in the exections incl. refactoring of code and
tests
- changes to the authn_keys table:
- added a `fingerprint` column
- dropped not null constraint on expiration
- moved the `GetSignerOnce` into its own package to prevent circular

One-time recovery codes are a common multi-factor authentication (MFA)
backup method, letting users access their account if they lose other MFA
devices. Support for recovery codes can also reduce support burden for
users locked out of their accounts and provide a more secure and
reliable form of verification than security questions.
# Which Problems Are Solved
Zitadel currently lacks support for recovery codes.
# How the Problems Are Solved
This PR partially addresses recovery code support in Zitadel.
Importantly, it adds recovery codes as a new 2FA `Factor` and an
additional `Check` type for the Session API.
```
Example recovery code flow:
1. User generates N new recovery codes using `POST /v2/users/{user_id}/recovery_codes`
2. Zitadel hashes and stores these codes and returns the un-hashed codes in the response
3. User creates new session with an additional check: `recoveryCode`
4. Code is checked against hash and, if valid, cannot be used again
5. User attempts to adds N more codes using the same endpoint
6. If `remaining_codes + N <= RecoveryCodes->MaxCount` config value, then recovery codes are added in addition to original codes
7. User can remove all recovery codes using `DEL /v2/users/:userId/recovery_codes`
```
This PR adds:
- [x] Session recovery_code check support on `POST+PATCH /v2/sessions`
endpoints
- [x] Adds `mfa_recovery_code_checked_at` column (default null) to
`projections.sessions8` table
- [x] Support for `SECOND_FACTOR_TYPE_RECOVERY_CODES` as available 2FA
method on login policy
- [x] Support for importing recovery codes in /import code
Missing, will _not_ implement in this PR:
- [ ] Admin console support for displaying Recovery Code settings for
user(s)
- [ ] Zitadel Typescript login support for recovery codes
