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.
