Token Generator
Cryptographically secure tokens, API keys and secrets via the Web Crypto API
About this tool
Generate cryptographically secure random tokens, API keys and secrets. Choose hex, Base64url or alphanumeric format with configurable length and count. Uses the Web Crypto API. Token Generator runs in the browser on DevTools. There is no signup, and your input stays on this device unless the tool explicitly performs a live network lookup.
What this tool does not do
- Token Generator is a free in-browser utility, not a hosted API. It does not keep server-side history and is not a substitute for production verification in your own stack.
