- There are numerous methods to verify a user's identity.
- One method is token-based authentication, which can be used in browsers, mobile apps, and mini-programs.
- The process involves the user applying for login on the client side, using credentials like username and password designed by the server.
- After successful verification, the server issues a token to the client.
- The client stores the token and uses it in subsequent requests' headers.
- The server then verifies the token's validity and authenticity to determine the requester's identity.
- The token contains encrypted data to prevent forgery.
- One specific method used for creating and verifying tokens is JWT (JSON Web Tokens).
