What is Token Generator?
A secure token generator: pick an alphabet and length to produce tokens with the right character set for your use case.
How it works
Bytes come from crypto.getRandomValues and are mapped onto the chosen alphabet (or formatted as hex) at the requested length.
- Enter your input. Type or paste your input into the field above — the tool responds instantly.

Examples
API and session secrets
Generate a URL-safe random token for API keys, reset links, or session secrets.
Common mistakes
Non-crypto randomness
For anything secret, the source must be cryptographically secure — Math.random() is never acceptable for tokens.
Frequently asked questions
How is the token generated?
From the browser's Web Crypto random source, encoded to your chosen format (hex, base64, or URL-safe base64).
How long should a token be?
128 bits of entropy (16 bytes) is a common minimum for API keys; the tool shows the entropy for the length you pick.
