JSON Web Token
Think of JWT like a movie ticket for your app. It proves who you are and what you're allowed to do.
Here's how it works:
- 1. Login: You log in to an app. - 2. JWT Creation: The server creates a token with your info (like user ID) and signs it with a secret. - 3. Token Use: The token is sent to your app, and every time you make a request, it’s sent back to prove it’s you. - 4. Server Verifies: The server checks the token's signature to confirm it hasn’t been tampered with.
Why use it?
JWT is self-contained, secure, and doesn’t require the server to store session data. Just make sure to avoid sensitive info in the token and always use HTTPS!
