What are some alternatives to OAuth for authentication in React Native?

There are several alternatives to OAuth for authentication in React Native, such as JWT (JSON Web Tokens), Basic Authentication, and OpenID Connect. Each has its own use cases and benefits.

Can you explain how JWT works for authentication?

Sure! JWT is a compact, URL-safe means of representing claims to be transferred between two parties. It consists of three parts: a header, a payload, and a signature. The server generates a token after user login, which the client can use for subsequent requests.

What are the security implications of using Basic Authentication?

Basic Authentication transmits credentials in an encoded format, which can be easily decoded. It's recommended to use it over HTTPS to secure the data in transit.

Are there any libraries you recommend for implementing these alternatives?

Yes! For JWT, you can use libraries like jsonwebtoken or react-native-jwt. For Basic Authentication, you can use the built-in fetch API with appropriate headers.
