What are the differences between OAuth and JWT in React Native?

What are the differences between OAuth and JWT in React Native?

OAuth is an authorization framework, while JWT (JSON Web Token) is a token format. OAuth allows third-party services to exchange information without sharing passwords, whereas JWT is used to securely transmit information between parties as a JSON object.

Can you explain how to implement OAuth in a React Native app?

To implement OAuth in a React Native app, you typically use libraries like react-native-app-auth. You'll need to set up an OAuth provider, configure your app with client ID and redirect URIs, and handle the authentication flow.

What about using JWT for authentication?

Using JWT for authentication involves generating a token upon user login, which is then sent with each request to verify the user's identity. You can use libraries like jsonwebtoken to create and verify tokens.

Which method is more secure?

Both methods can be secure if implemented correctly. OAuth is generally considered more secure for delegated access, while JWT is great for stateless authentication. It depends on your specific use case.
