FIDO2 vs OpenID Connect

Developers should learn and implement FIDO2 to enhance security in applications by eliminating passwords, which are vulnerable to breaches and phishing meets developers should learn and use openid connect when building applications that require secure user authentication and identity verification, such as enterprise sso systems, consumer-facing apps with social login, or any service needing to integrate with identity providers like google, microsoft, or okta. Here's our take.

FIDO2

Nice Pick

Developers should learn and implement FIDO2 to enhance security in applications by eliminating passwords, which are vulnerable to breaches and phishing

Pros

• It is particularly useful for high-security environments like banking, healthcare, and enterprise systems, as well as consumer-facing services seeking to improve user experience with biometric or hardware-based logins
• Related to: webauthn, public-key-cryptography

Cons

• Specific tradeoffs depend on your use case

OpenID Connect

Developers should learn and use OpenID Connect when building applications that require secure user authentication and identity verification, such as enterprise SSO systems, consumer-facing apps with social login, or any service needing to integrate with identity providers like Google, Microsoft, or Okta

Pros

• It simplifies authentication flows by standardizing token-based identity verification, reducing the need for custom authentication code and enhancing security through built-in features like token validation and user consent management
• Related to: oauth-2.0, json-web-tokens

Cons

• Specific tradeoffs depend on your use case

The Verdict

These tools serve different purposes. FIDO2 is a concept while OpenID Connect is a protocol. We picked FIDO2 based on overall popularity, but your choice depends on what you're building.

The Bottom Line

FIDO2 wins

Based on overall popularity. FIDO2 is more widely used, but OpenID Connect excels in its own space.
