Description

A generic AuthenticationFilter class was added in #6506 to v5.2, but there still isn't any documentation to explain why or how to use it.

Would it be ideal for a web API that uses a form of username/password authentication using custom headers (Client-ID, Client-Secret)? This feels like a simple use case but one that still appears to require a custom filter.

Research direction

Start by reviewing the generic AuthenticationFilter introduced in #6506 and the surrounding Spring Security documentation entry points. Explain why the class exists, how it is used, and whether username/password authentication with Client-ID and Client-Secret headers is an appropriate use case or still requires a custom filter. Done means the documentation answers these usage questions clearly.
