OAuth 1.0a

Nice Pick

Developers should learn OAuth 1

Pros

• 0a when building applications that need to securely interact with APIs that require user authorization, such as social media integrations or data-sharing services
• Related to: oauth-2.0, api-authentication

Cons

• Specific tradeoffs depend on your use case

OAuth 2.0

Developers should learn OAuth 2

Pros

• 0 when building applications that need to integrate with external services like Google, Facebook, or GitHub, as it provides a standardized way to handle authentication and authorization
• Related to: openid-connect, jwt

Cons

• Specific tradeoffs depend on your use case

The Verdict

Use OAuth 1.0a if: You want 0a when building applications that need to securely interact with apis that require user authorization, such as social media integrations or data-sharing services and can live with specific tradeoffs depend on your use case.

Use OAuth 2.0 if: You prioritize 0 when building applications that need to integrate with external services like google, facebook, or github, as it provides a standardized way to handle authentication and authorization over what OAuth 1.0a offers.

The Bottom Line
