FAQ
What makes these tokens secure?
The tokens are generated using the browser's cryptographically secure random number generator (window.crypto.getRandomValues). This is much safer than standard pseudo-random number generators.
Which format should I use for a JWT secret?
Base64URL or Hex formats of 32 bytes (256 bits) or 64 bytes (512 bits) are standard and highly recommended for JWT signing keys.
Are these tokens saved on any server?
No. All generation happens locally in your browser. Once you close the tab, the generated tokens are gone forever unless you copy them.
