Authentication
A user authentication service provided by Firebase that supports multiple sign-in methods, including email and password, Google, and anonymous login, and manages user accounts and login credentials.

On each tool call, the Gateway must answer two questions: Authentication addresses "who is calling", and Authorization addresses "what the caller is allowed to do".
Authentication only confirms identity, while authorization determines the boundary; handling the two together easily leads to the vulnerability of "once connected, everything is allowed".
A robust authentication process should include receiving a token or credential, independently verifying it against a trusted source on the server side, and granting permissions only after verification passes.
Authentication confirms "who you are," authorization confirms "what you can do," and in terms of process, authentication precedes authorization, meaning unauthenticated requests do not enter the authorization process.
Authentication addresses the question of 'who you are,' while authorization addresses the question of 'what you can do'; the two are fundamentally different in system design.
