Random Token Generator
Crypto-Secure Strings
Generate cryptographically secure random tokens, secret keys, API strings, and passwords with custom length and character sets
What is Random Token Generator?
The Random Token Generator is a cryptographically secure string generator that creates unguessable tokens, API keys, secret hashes, session identifiers, and high-entropy passwords directly in your browser. Powered by standard Web Crypto APIs (crypto.getRandomValues), every token is generated using true cryptographic randomness with zero modulo bias. You can customize character sets (uppercase, lowercase, numbers, symbols, hexadecimal, or custom characters), set exact lengths from 4 to 1024+ characters, apply prefixes or chunk formatting (such as license-key hyphenation), and batch generate up to 50 tokens at once with one-click export.
How to Use Random Token Generator
Choose your preset or character set
Select from popular developer presets like API Key, URL-Safe NanoID, Hex Secret, or toggle specific character types (uppercase, lowercase, numbers, symbols).
Adjust length and options
Slide the length bar or type the exact count (4 to 1024). Optionally enable 'Exclude Ambiguous' characters or add custom prefixes and chunk separators.
Generate or batch generate
Tokens generate automatically upon changing options, or hit 'Generate Token' / 'Refresh' for fresh values. Switch count to generate multiple tokens at once.
Copy or export
Click 'Copy' for instant clipboard access, 'Copy All' for batch tokens, or 'Download .txt' to save your tokens locally.
Key Features
Cryptographically secure randomness using window.crypto.getRandomValues (CSPRNG)
Developer presets for API keys, bearer tokens, hex secrets, NanoID url-safe tokens, and passwords
Customizable character pools: uppercase (A-Z), lowercase (a-z), digits (0-9), symbols, or custom characters
Option to exclude ambiguous characters (0, O, 1, l, I) to prevent human reading mistakes
Accurate real-time entropy calculation in bits (e.g., 256-bit, 512-bit security rating)
Prefix, suffix, and custom chunk separator support (e.g., xxxx-xxxx-xxxx)
Batch mode: generate 1, 5, 10, 20, or 50 tokens at once with bulk copy and TXT export
Persistent recent token history with one-click copy and clear
100% client-side execution - generated tokens never travel across the internet
Tips & Best Practices
- 1
For API keys and webhook secrets, 32 to 64 alphanumeric characters provide over 190 to 380 bits of entropy - far exceeding brute-force vulnerability.
- 2
If humans need to read or manually type your tokens (such as activation codes), enable 'Exclude Ambiguous' and add hyphen chunking.
- 3
For database identifiers and URLs, choose the URL-Safe preset (letters, digits, '-' and '_') to avoid percent-encoding issues.
- 4
Never commit secret tokens or private API keys directly into public git repositories; store them in environment variables.
- 5
Save frequently generated token patterns as templates in your workflow for fast re-use.
