Generate a Secure API Key
Create random, high-entropy strings for use as API keys, secret tokens, and signing secrets.
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.
