JWT Authentication vs OAuth 2.0

Developers should use JWT Authentication when building stateless APIs, microservices, or single-page applications (SPAs) that require scalable, cross-domain authentication without server-side session storage meets developers should learn oauth 2. Here's our take.

JWT Authentication

Nice Pick

Developers should use JWT Authentication when building stateless APIs, microservices, or single-page applications (SPAs) that require scalable, cross-domain authentication without server-side session storage

Pros

• It's particularly useful for scenarios like mobile app logins, third-party API integrations, and real-time applications where tokens can be easily validated and contain custom claims for authorization
• Related to: oauth-2.0, openid-connect

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 JWT Authentication if: You want it's particularly useful for scenarios like mobile app logins, third-party api integrations, and real-time applications where tokens can be easily validated and contain custom claims for authorization 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 JWT Authentication offers.

The Bottom Line

JWT Authentication wins

Developers should use JWT Authentication when building stateless APIs, microservices, or single-page applications (SPAs) that require scalable, cross-domain authentication without server-side session storage
