Certificate-Based Authentication

Developers should learn and use certificate-based authentication when building secure applications that require high-assurance identity verification, such as in financial systems, healthcare platforms, or IoT device management

Pros

• It is particularly valuable for scenarios like server-to-server communication, VPN access, and API security, where it reduces reliance on passwords and mitigates risks like phishing or credential theft
• Related to: public-key-infrastructure, ssl-tls

Cons

• Specific tradeoffs depend on your use case

The Verdict

These tools serve different purposes. SSH Keys is a tool while Certificate-Based Authentication is a concept. We picked SSH Keys based on overall popularity, but your choice depends on what you're building.

The Bottom Line

SSH Keys wins

Based on overall popularity. SSH Keys is more widely used, but Certificate-Based Authentication excels in its own space.
