What are the differences between OAuth and CAS?

What are the differences between OAuth and CAS?

OAuth is an authorization framework that allows third-party services to exchange information without sharing credentials, while CAS (Central Authentication Service) is a single sign-on protocol that enables users to authenticate once and gain access to multiple applications.

Can you explain how OAuth works in more detail?

Sure! OAuth works by allowing users to grant limited access to their resources on one site to another site without sharing their credentials. It uses tokens to manage this access.

What are the advantages of using CAS over OAuth?

CAS provides a centralized authentication service, which simplifies user management and enhances security by reducing the number of credentials users need to remember.

Are there any scenarios where I should prefer OAuth over CAS?

Yes, if you need to allow third-party applications to access user data without sharing passwords, OAuth is the better choice.
