What is OAuth 2.0 and how does it work with JWT?

OAuth 2.0 is an authorization framework that allows third-party applications to obtain limited access to user accounts. JWT, or JSON Web Token, is a compact token format used to securely transmit information between parties. Together, they enable secure authentication and authorization.

Can you explain how JWT is used in the OAuth 2.0 flow?

Sure! In the OAuth 2.0 flow, after a user grants permission, the authorization server issues a JWT as an access token. This token contains claims about the user and can be used by the client to access protected resources.

What are the benefits of using JWT with OAuth 2.0?

Using JWT with OAuth 2.0 provides benefits like stateless authentication, reduced server load, and the ability to include custom claims, making it easier to manage user sessions.

Are there any security concerns I should be aware of?

Yes, some concerns include token expiration, secure storage of tokens, and ensuring the integrity of the JWT. Always use HTTPS and validate tokens properly.
