Description :

User Registration API: Handles new user signups. Accepts user data (username, email, password). Securely stores user information (hashed and salted passwords).
User Login API: Verifies user credentials. Compares entered password with stored hash. Upon successful authentication, generates and returns a token (e.g., JWT).
User Verification API: Fetches and returns user profile information. Requires a valid authentication token.
Token Refresh API: Issues new access tokens upon expiration. Extends user sessions without requiring re-login.
The tutorial provides clear instructions and ready-to-use source code for each of these APIs.
