Summary#
Swagger UI token refresh limits
Problem#
Teams may expect FastAPI's Swagger UI to automatically refresh expired JWTs during interactive API use.
Solution#
Do not assume Swagger UI handles full refresh-token workflows automatically. persistAuthorization can preserve auth data across reloads, but token refresh usually belongs in a real client or a custom docs integration if you need that behavior.
Failure Modes#
- Confusing persisted authorization with automatic token refresh
- Relying on Swagger UI behavior as proof that production auth UX is correct
- Building on incomplete or placeholder research without validating the actual refresh flow
