Password Generator
Generate strong, random passwords
What is Password Generator?
A cryptographically secure password generator creates random passwords using your browser's built-in cryptographic random number generator (Web Crypto API), ensuring maximum entropy and unpredictability.
When to use this tool
- Creating new account passwords
- Generating API keys and tokens
- Setting up database credentials
- Creating WiFi passwords
- Any situation requiring a strong, unique password
How it works
Uses the Web Crypto API (window.crypto.getRandomValues) to generate cryptographically secure random bytes, then maps them to your chosen character set. Unlike Math.random(), this is suitable for security-critical applications.
Security Guidelines
- Use at least 16 characters for important accounts
- Never reuse passwords across different services
- Store passwords in a password manager (1Password, Bitwarden)
- Enable two-factor authentication whenever possible
- Avoid using personal information in passwords
