When should I use OAuth or JWT?

Can you explain when to use OAuth and when to use JWT?

Sure! OAuth is typically used for authorization, allowing third-party applications to access user data without sharing credentials. JWT, on the other hand, is often used for securely transmitting information between parties as a JSON object.

So, if I have a web app that needs to access user data from another service, I should use OAuth?

Exactly! OAuth is designed for that purpose. It allows your app to request access tokens from the user, which can then be used to access their data.

And what about JWT? When should I use that?

JWT is great for scenarios where you need to verify the identity of a user or transmit information securely. It's often used in stateless authentication.

Can I use both OAuth and JWT together?

Yes, you can! In fact, OAuth can use JWT as a token format, combining the benefits of both for secure authorization and information exchange.
