Generate strong, cryptographically secure random passwords.

Input
Generated Password

📖 What is Password Generator?

This password generator uses the Web Crypto API (crypto.getRandomValues) to generate cryptographically secure random passwords. Unlike Math.random()-based generators, these passwords are truly unpredictable and safe for use in security-sensitive applications.

💡 Example

Input
Length: 16, All character types
Output
K9#mP2@xL5&vN8!q

🛠️ Common Use Cases

  • Generating strong passwords for new accounts
  • Creating temporary passwords for user onboarding
  • Generating API keys and secrets
  • Creating database passwords for production systems
  • Testing password strength validation logic

❓ Frequently Asked Questions

How secure is this generator?
It uses crypto.getRandomValues(), the same API used by password managers and security tools. This is cryptographically secure randomness, not pseudo-random.
What makes a strong password?
Length matters most. A 16+ character password with mixed case, numbers and symbols is extremely strong. Length beats complexity — 'correct horse battery staple' is stronger than 'Tr0ub4dor&3'.
Is my generated password saved anywhere?
No — passwords are generated and displayed only in your browser. Nothing is ever sent to a server. Close the tab and the password is gone.
How many characters should my password be?
At minimum 12, ideally 16+. For high-security accounts (banking, email), use 20+ characters.
