Fill in the fields above to see your result.
What it does
Secure Token Generator produces its output in your browser using the platform's own cryptographic random source where randomness matters — not a seeded pseudo-random shortcut. API keys and random secrets.
When you need it
Whenever you need a value that has to be correct rather than approximately right, and typing one yourself would either be predictable or a formatting mistake waiting to happen.
Limits and caveats
Nothing is generated on a server, logged, or recoverable — if you close the tab without copying the result, it is genuinely gone. Keep anything you intend to rely on in a password manager rather than in this page. Everything happens in your browser, so the file never leaves your device.
