What are the different authentication methods for API security?

There are several authentication methods for API security, including API keys, OAuth, JWT, and Basic Auth. Each has its own use cases and security levels.

Can you explain how OAuth works?

OAuth is an open standard for access delegation, commonly used for token-based authentication. It allows users to grant third-party applications access to their resources without sharing their credentials.

What are the advantages of using JWT over other methods?

JWT, or JSON Web Tokens, are compact and self-contained, allowing for stateless authentication. They can carry claims and are easy to verify, making them a popular choice for modern APIs.

Are there any security risks I should be aware of?

Yes, common risks include token theft, replay attacks, and improper token storage. It's essential to implement best practices like HTTPS, token expiration, and secure storage.
