API Keys tips

🔑

API keys should be at least 32 characters of random data. Use all character types (uppercase, lowercase, numbers, symbols) for maximum entropy.

🔒

Store generated API keys in environment variables or a secrets manager — never hard-code them in source files.

💡

For JWT signing secrets and OAuth client secrets, 64+ character random strings are recommended to prevent brute-force attacks.

🔄

Rotate API keys regularly. Generate a new key, update your application, then revoke the old key — always in that order to avoid downtime.
