Token Generator

Secure Random Token Tool

Generate cryptographically secure random tokens, API keys, PINs, and UUIDs in your browser.

About Secure Tokens

A token is a random string used to identify, authenticate, or authorize something, for example an API key, a session ID, a password-reset link, or a one-time PIN. For security, tokens must be generated with a cryptographically secure random number generator. This tool uses crypto.getRandomValues() from the Web Crypto API, which is suitable for security-sensitive use, unlike Math.random() which is predictable and must never be used for secrets.

Choose the format that fits your need: Hex and Base64 are common for API keys and secrets, Base64URL is safe to use in URLs and filenames, Alphanumeric avoids special characters, a Numeric PIN is handy for short verification codes, and UUID v4 produces a standard 128-bit random identifier. The longer the token, the harder it is to guess. Everything is generated locally in your browser and nothing is sent to a server.
