Strong Password Generator
Generate strong, secure random passwords locally in your browser. Choose length and character types with guaranteed inclusion.
Generated entirely in your browser using cryptographically secure randomness. No passwords are stored or transmitted.
How it works
This tool uses the browser’s secure cryptographic APIs (crypto.getRandomValues()) to generate random characters.
It guarantees at least one character from each selected character set.
- Custom length: 8–64 characters
- Character sets: uppercase, lowercase, numbers, symbols
- High entropy: Longer passwords with more character sets increase security
Examples
- Length 16 + letters + numbers → strong general account password
- Length 24 + symbols → high-entropy password for critical accounts
- Length 32+ → maximum security for password managers
