# 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 --------- Co-authored-by: Cursor <cursoragent@cursor.com>
