How can I handle different authentication methods in my app?

You can implement various authentication methods like OAuth, JWT, and traditional username/password. What specific methods are you considering?

I'm thinking about using OAuth and JWT. How do they differ?

OAuth is an authorization framework that allows third-party services to exchange information without sharing passwords. JWT, or JSON Web Tokens, is a compact way to securely transmit information between parties as a JSON object. They can be used together for secure authentication.

What are the security implications of using these methods?

Using OAuth and JWT can enhance security by reducing password exposure and enabling token-based authentication. However, it's crucial to implement them correctly to avoid vulnerabilities like token theft.
