crudauth

Use when building or modifying authentication in a FastAPI app with crudauth (the `crudauth` PyPI package) — covers `CRUDAuth`, the `AuthUserMixin` / `make_auth_identity` user model, `IdentityConfig`, `current_user(...)` gates, session + bearer transports, OAuth (Google/GitHub), email verification / password reset / change, custom email bodies (`EmailSender` / `EmailContext` / `DeliveryChannel`), registration allowlists and provisioning, sudo mode, and account shapes (email, username-only, phone recovery). Activate when the code imports `crudauth`, defines a `CRUDAuth(...)`, a `current_user` dependency, an `AuthUserMixin` model, or an `EmailSender`, or when the user asks to add login / signup / sessions / JWT / OAuth / email verification to a FastAPI app, even without naming the library.
