Overview
Authentication choices affect user experience, security, operations, and vendor coordination. OAuth, OpenID Connect, and SAML solve related but different problems.
Practical Comparison
- SAML is common in enterprise SSO scenarios
- OpenID Connect is widely used for modern web and mobile applications
- OAuth is primarily about delegated authorization
- Identity provider configuration must be tested in each environment
Key Takeaways
Choose the protocol based on the application, identity provider, vendor support, and operational model rather than popularity alone.
