JWT

JWT, or JSON Web Token, is a secure way to transmit information between parties electronically. It functions like a digital badge containing verified details, such as your identity or permissions, encoded in a way that confirms its authenticity. When you log into a website or app, you're given a JWT, which you present to access different parts of the service without repeatedly logging in. The token is signed with a secret key, ensuring it hasn't been tampered with. This helps maintain secure, efficient communication while keeping user data safe.
