Login & JWT Generation
Build a user login system that issues and manages JSON Web Tokens (JWTs) for session management.
Welcome to Login Systems
In the previous lesson, we learned about user registration and secure password hashing. Now, it's time to build the login system!
A login system allows authenticated users to access protected resources and personalize their experience within your SaaS application.
How Login Works (Overview)
When a user tries to log in, they typically provide a username (or email) and a password. Here's the basic flow:
- The client (e.g., your mobile app) sends credentials to the server.
- The server verifies these credentials against its stored user data.
- If valid, the server grants access.
