# Changelog

## v2.0.0 (unreleased)

### Breaking Changes

#### Refresh token rotation enforced

Refresh tokens are now single-use. Each token exchange returns a new refresh token; reusing a previously consumed refresh token revokes all tokens for that user as a security measure. Clients must store the new refresh token from every response. (#163)

#### PKCE required for public clients

Public clients must include a `code_challenge` (S256) in authorization requests. Requests without PKCE are rejected with `invalid_request`. (#54, #162)

#### Access token audience always populated

Access tokens now include `[issuer, client_id]` in the `aud` claim. Per-client `allowed_audiences` extend (not replace) these defaults. Existing consumers that assume an empty audience will need to update their token validation. (#178)

#### Admin API requires `autentico-admin` audience

Admin API endpoints now require `autentico-admin` in the token `aud` claim, in addition to the admin role. Tokens without a matching audience are rejected with 403. (#187)

#### Account API requires audience claim

All `/account/api/*` endpoints now require `autentico-account` or `autentico-admin` in the `aud` claim. Tokens without a matching audience are rejected with 401. Ensure clients that need account API access have `autentico-account` in their `allowed_audiences` configuration. (#320)

#### `given_name` / `family_name` moved to ID token

These claims are no longer included in access tokens. They are available in ID tokens (when `profile` scope is requested) and from the `/oauth2/userinfo` endpoint. Clients that parsed these from access tokens must switch to ID tokens or UserInfo. (#222)

#### List endpoints return paginated response objects

All admin list endpoints (`/admin/api/users`, `/admin/api/groups`, `/admin/api/clients`, `/admin/api/federation`, `/admin/api/sessions`, `/admin/api/audit`, `/admin/api/tokens`, `/admin/api/deletions`) now return `{ "items": [...], "total": N }` instead of raw arrays. Server-side sorting, filtering, search, and pagination are supported via query parameters. (#254)

#### Bearer token logout removed

`POST /oauth2/logout` no longer accepts Bearer tokens. Only RP-Initiated Logout (OIDC RP-Initiated Logout 1.0) with form-encoded `id_token_hint` and `post_logout_redirect_uri` parameters is supported. `GET /oauth2/logout` is also supported per spec. (#107, #134)

#### JWKS endpoint moved

The JWKS endpoint moved from `/.well-known/jwks.json` to `/oauth2/.well-known/jwks.json`. The discovery document reflects the new location. (#105)

#### CORS configuration changed

The `AUTENTICO_APP_ENABLE_CORS` environment variable has been removed. CORS allowed origins are now configured at runtime via the `cors_allowed_origins` setting in the admin API. (#161)

#### Cross-client token isolation

Token introspection and revocation endpoints now enforce client isolation. A client can only introspect or revoke tokens it issued. Tokens from other clients return `active: false` (introspect) or succeed silently (revoke) per RFC. (#189)

#### Signed authorize parameters

The authorization flow now uses HMAC-signed parameters to prevent form tampering. Direct `POST` to `/oauth2/login` without going through `/oauth2/authorize` will fail. (#191)

### New Features

#### OAuth2 / OIDC Protocol

- **Device Authorization Grant (RFC 8628)** — new `/oauth2/device_authorization` endpoint, polling via `/oauth2/token`, with user verification flow in the account UI (#344)
- **Client Credentials Grant (RFC 6749 section 4.4)** — machine-to-machine authentication without user involvement (#152)
- **OAuth2 Consent Screen** — per-client `consent_required` setting with scope approval UI; consent decisions are remembered per user+client+scopes (#290, #311)
- **`prompt=create` support** — OIDC-compliant signup redirect via the authorization endpoint (#148)
- **`at_hash` claim** in ID tokens per OIDC Core 3.1.3.6 (#169)
- **Email claims in ID token** when `email` scope is requested (#221)
- **Configurable OAuth path** — `AUTENTICO_APP_OAUTH_PATH` env var to override the default `/oauth2` prefix (#339)

#### Authentication & Security

- **MFA method switching** — users with TOTP enrolled can switch to email OTP during MFA verification; configurable via `mfa_method` setting (`totp`, `email`, `both`) (#310, #311)

- **Scope validation** on the authorize endpoint (#328)
- **Stored XSS fix** in auth views via federation icon and theme CSS (#219)
- **SSRF prevention** on federation OIDC discovery (#181)
- **Password confirmation for sensitive actions** — profile changes, MFA enrollment/disable, and passkey management require `current_password` to prevent unauthorized modifications (#347)
- **Password oracle fix** on TOTP disable and password change endpoints (#319)

#### Admin UI

- **Dark mode toggle** with Ant Design 6 and Vite 8 (#274)
- **Server-side pagination, sorting, filtering, and search** across all list pages — users, groups, clients, sessions, federation, audit, tokens, deletions (#254, #257, #260, #262, #266, #267, #270)
- **Per-device IdP sessions** page with cascade revocation (#237, #242)

- **`sso_session_max_age`** — absolute session lifetime in addition to idle timeout (#282)
- **Idle timeout cascade** — deactivating an IdP session cascades to child OAuth sessions and tokens (#280)
