What are the differences between OpenID and SAML?

OpenID is an authentication protocol that allows users to log in to multiple websites using a single set of credentials, while SAML (Security Assertion Markup Language) is used for single sign-on (SSO) and allows secure exchange of authentication and authorization data between parties.

Which one is better for enterprise applications?

SAML is generally preferred for enterprise applications due to its robust security features and support for SSO across different domains.

Can you give me an example of when to use OpenID?

OpenID is ideal for consumer-facing applications where users want to log in using their existing accounts from providers like Google or Facebook.

Are there any security concerns with either of them?

Yes, both have their security considerations. OpenID can be vulnerable to phishing attacks, while SAML requires careful implementation to avoid issues like XML signature wrapping.
