• Related to: authentication, security-best-practices

Cons

• Specific tradeoffs depend on your use case

Single Sign-On

Developers should implement SSO when building enterprise applications, SaaS platforms, or any system requiring secure access to multiple services, as it streamlines user authentication and reduces the risk of password-related security breaches

Pros

• It is particularly useful in corporate environments where employees need to access various internal tools, or in consumer-facing applications that integrate with third-party services, as it simplifies login processes and supports compliance with security standards like OAuth and SAML
• Related to: oauth-2.0, saml

Cons

• Specific tradeoffs depend on your use case

The Verdict

Use Two-Factor Authentication if: You want it is crucial for compliance with security standards like gdpr or pci-dss and helps prevent common attacks such as phishing, credential stuffing, and password breaches and can live with specific tradeoffs depend on your use case.

Use Single Sign-On if: You prioritize it is particularly useful in corporate environments where employees need to access various internal tools, or in consumer-facing applications that integrate with third-party services, as it simplifies login processes and supports compliance with security standards like oauth and saml over what Two-Factor Authentication offers.
