Frequently asked questions
Everything you need to know about random token generator.
Yes. Tokens are generated using the Web Crypto API's crypto.getRandomValues(), which provides cryptographically secure randomness suitable for security-sensitive use cases.
Hexadecimal (0-9, a-f), Base64 (URL-safe), and alphanumeric (A-Z, a-z, 0-9). Hex is common for API keys; Base64 is compact; alphanumeric is URL-safe.
32 characters (256 bits) is the standard for session tokens and API keys. 64 characters (512 bits) provides extra security for long-lived secrets. 16 characters is sufficient for CSRF tokens.
Yes. Generate a hex or alphanumeric token of 32+ characters for a secure API key. Store it in an environment variable and never commit it to source control.
No. Everything is generated locally in your browser using the Web Crypto API. Nothing is transmitted or stored.
