Here's our take.

Certificate-Based Authentication

Nice Pick

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

SSH Keys
