What Is Secure Token Generator?

The Secure Token Generator mints API keys, hex secrets, Base64URL tokens, numeric PINs, and UUID v4 values with cryptographic randomness from crypto.getRandomValues(). Every token shows its entropy in bits, so you can size secrets to the threat instead of guessing.

Who Uses the Secure Token Generator?

Developers provisioning API keys, secrets, and test fixtures use it to avoid the birthday collisions of Math.random tokens.

How to Use the Secure Token Generator

  1. Pick hex, Base64URL, alphanumeric, PIN, or UUID.
  2. Set the length and read the entropy estimate.
  3. Copy the token into your config or code.

Why Choose Our Secure Token Generator?

  • CSPRNG-backed, never Math.random
  • Five formats from PINs to UUIDs
  • Entropy in bits shown per token
