Authentication¶

FastAPI Users allows you to plug in several authentication methods.

How it works?¶

You can have several authentication methods, e.g. a cookie authentication for browser-based queries and a JWT token authentication for pure API queries.

When checking authentication, each method is run one after the other. The first method yielding a user wins. If no method yields a user, an HTTPException is raised.

For each backend, you'll be able to add a router with the corresponding /login and /logout (if applicable routes). More on this in the routers documentation.
