Random Token Generator
Free random token generator online. Create cryptographically secure API keys, session tokens, OTP codes, and secrets with custom length, charset, and batch export. Uses Web Crypto API — 100% client-side.
Cryptographic Security
Tokens are generated using the Web Crypto API (crypto.getRandomValues()) — the same CSPRNG used by TLS, SSH, and blockchain wallets. All computation runs locally in your browser via a dedicated Web Worker. Your tokens never leave your device.
How to Use Random Token Generator
Navigate to the Random Token Generator page. This tool runs entirely in your browser for maximum security.
Enter the text, hash, or data you want to process. No data is ever transmitted to our servers.
The tool generates results instantly using industry-standard cryptographic algorithms implemented in JavaScript.
Review the output, copy it, or use it in your security workflow. All operations are stateless — nothing is stored.

Frequently Asked Questions
Is this random token generator cryptographically secure?▼
Yes. This tool uses the Web Crypto API (crypto.getRandomValues()), the same CSPRNG that powers TLS, SSH keys, and blockchain wallets. Every token is generated entirely in your browser — no data is sent to any server.
What is the best token length for API keys?▼
For API keys, 32–64 characters using an alphanumeric character set provides 190–380 bits of entropy, which is considered very strong. For session tokens, 64 hex characters (256 bits) is the industry standard.
Can I generate multiple tokens at once?▼
Yes. Use the 'Count' option under Advanced Options to generate up to 50 tokens in a single batch. You can copy all of them or download them as a .txt file.
Does this tool store or log my generated tokens?▼
No. All token generation happens locally in your browser using a dedicated Web Worker. We have zero server-side processing and zero logging. Your tokens never leave your device.
What character sets are available?▼
10 built-in character sets: Alphanumeric, Alphabetic, Numeric, Hexadecimal (lower/upper), Base64, Base64 URL-safe, Alphanumeric + Symbols, Uppercase + Digits, and Lowercase + Digits. You can also define a custom character set.
