Token Generator
Generate secure, random strings with customized characters instantly in your browser.
Cryptographically Secure Tokens, Instantly
Need an API key, a secret, or a session token? This free generator creates cryptographically secure random tokens using your browser's Web Crypto API — the same randomness source modern platforms rely on.
Choose the token length, generate as many as you like, and copy with one click. Generation happens locally, so your tokens are never transmitted or logged.
Web Crypto randomness
Tokens are built with crypto.getRandomValues, the browser's cryptographically secure random number generator — not Math.random.
Length control and one-click copy
Set the token length to match your system's requirements and copy each token straight to your clipboard.
Private by design
Because tokens are generated locally in your browser, they never pass through a server — no logging, no storage, no exposure.
How to use
- Set your desired token length.
- Click Generate Token.
- Copy the token with the copy button and paste it where you need it.
Frequently Asked Questions
What makes these tokens secure?
They use the Web Crypto API's cryptographically secure random number generator, suitable for API keys, secrets, and session tokens.
Are generated tokens stored anywhere?
No. Tokens are generated locally in your browser and are never sent to or stored on any server.
What token length should I use?
128 bits (about 22 URL-safe characters) is the modern minimum for secrets; many APIs use 256-bit tokens — longer is safer.
Can I use these as passwords?
You can, but the dedicated password generator mixes character classes for memorability rules — either works for random secrets.
Is the generator free?
Yes, free with no signup or limits.
