HTTP has a general authentication framework that defines a pattern into which various authentication schemes can fit. Clients may provide an authorization request header that contains a credential. If authorization is missing or invalid, the server may respond with a 401 (Unauthorized) status code, including a www-authenticate header advertising what authentication schemes are supported. Otherwise, the server can respond with the authenticated resource.

Learn how to implement HTTP Bearer authentication in Django without heavyweight frameworks. The guide demonstrates creating a simple token-based authentication system using the HTTP authorization header, including a complete working example with a view function, unit tests, and a reusable decorator pattern. The implementation uses secrets.compare_digest() to prevent timing attacks and properly handles 401 responses with www-authenticate headers according to HTTP standards.
