What are the differences between OAuth and JWT?

OAuth is an authorization framework, while JWT (JSON Web Token) is a token format often used within OAuth.

Can you explain how they are used in real-world applications?

Sure! OAuth is commonly used for granting third-party applications access to user data, like logging in with Google. JWT is often used for securely transmitting information between parties, like user authentication.

Which one is more secure?

Both have their security features, but OAuth can be more secure when implemented correctly, as it allows for token expiration and scopes.

Are there scenarios where I should use one over the other?

Yes, use OAuth when you need delegated access and JWT when you need a compact, self-contained token for authentication.
