A random hex token is a string of hexadecimal characters used as a secure, unguessable identifier in web applications and APIs. Hex tokens are commonly used for password reset links, email verification codes, API keys, CSRF tokens, and OAuth secrets. This generator lets you choose the exact length and add a custom prefix such as tok_ or sk_ to match your application's token format. A 32-character hex token gives you 128 bits of entropy, which is widely considered secure for most applications.
A 32-character hex token (128 bits) is the industry standard for most security tokens. For very high-security uses, 64 characters (256 bits) is recommended.
A hex token is a plain random hex string with no fixed format, while a UUID follows a specific 8-4-4-4-12 structure with version bits embedded.
Yes — hex tokens with a recognisable prefix like sk_ or pk_ are a popular format for API keys used by services like Stripe and GitHub.
They are generated with Math.random(), which is suitable for most development and testing purposes. For production security tokens, use a cryptographic library on your server.
