Token Generator
Generate cryptographically secure tokens, passwords and API keys
Character sets
Cryptographically secure
Uses window.crypto.getRandomValues() — the same standard as password managers and security APIs. No weak Math.random() pseudo-randomness.
Complete privacy
Tokens are generated exclusively in your browser. No network request, no server, no logs. Your generated strings are visible only to you.
Versatile use cases
From API keys to session tokens, secure passwords and PINs — configurable character sets (A–Z, a–z, 0–9, symbols) for every use case.
Frequently asked questions
Everything about secure token generation in the browser
The Token Generator uses the Web Crypto API (window.crypto.getRandomValues()), which produces cryptographically secure pseudo-random numbers. This standard is used by banks, password managers, and security APIs worldwide. The output is unpredictable and suitable for all security-critical applications.
No. All tokens are generated exclusively in your browser — no network request or server upload takes place. The generated strings never leave your browser unless you copy them yourself.
For API keys we recommend at least 32 characters (alphanumeric), ideally 64. A 64-character alphanumeric string provides over 380 bits of entropy — far more than required for practical security (128 bits is considered sufficient). For passwords, 16–20 characters with all character sets enabled is more than adequate.
Entropy measures the randomness of a token. It is calculated as length × log₂(character pool size). From 128 bits, a token is considered cryptographically secure against brute-force attacks. From 256 bits, it is practically uncrackable — even with all the computing power on Earth, an attack would take longer than the age of the universe.
API Key (64 chars, alphanumeric): Ideal for authentication tokens, webhook secrets and session IDs. Password (20 chars, all sets): Maximum password complexity for account passwords. PIN (6 digits): Numeric codes for SMS verification. Hex Token (32 chars, 0-9 + a-f): Compatible with systems that expect hexadecimal tokens.
