What are the different authentication methods for pub-sub systems?

There are several authentication methods for pub-sub systems, including token-based authentication, OAuth, and API keys. Each has its own use cases and security implications.

Can you explain how token-based authentication works?

Sure! In token-based authentication, a user logs in and receives a token that they must include in subsequent requests. This token is usually time-limited and can be revoked.

What are the advantages of using OAuth for pub-sub?

OAuth allows for delegated access, meaning users can grant third-party applications limited access to their resources without sharing their credentials. This enhances security and user control.

Are there any downsides to using API keys?

Yes, API keys can be less secure if not managed properly. They can be exposed in client-side code, and if compromised, they can allow unauthorized access.
