Here's our take.

Cookie-Based Authentication

Nice Pick

Developers should use cookie-based authentication when building traditional web applications with server-side rendering (e

Pros

• g
• Related to: session-management, http-cookies

Cons

• Specific tradeoffs depend on your use case

API Key Authentication

Developers should use API Key Authentication when building or consuming APIs that require straightforward, stateless authentication without complex user sessions, such as for machine-to-machine interactions, microservices, or public APIs with limited access tiers

Pros

• It's ideal for scenarios where scalability and simplicity are priorities, but it should be combined with HTTPS to prevent key exposure and may be supplemented with rate limiting or IP whitelisting for enhanced security
• Related to: oauth-2, jwt-authentication

Cons

• Specific tradeoffs depend on your use case

The Verdict

Use Cookie-Based Authentication if: You want g and can live with specific tradeoffs depend on your use case.

Use API Key Authentication if: You prioritize it's ideal for scenarios where scalability and simplicity are priorities, but it should be combined with https to prevent key exposure and may be supplemented with rate limiting or ip whitelisting for enhanced security over what Cookie-Based Authentication offers.

The Bottom Line

Cookie-Based Authentication wins

Developers should use cookie-based authentication when building traditional web applications with server-side rendering (e
