How to Generate Strong, Secure Passwords
- Select desired password length (12 to 64 characters; 16+ recommended).
- Toggle character sets: Uppercase (A-Z), Lowercase (a-z), Numbers (0-9), and Symbols (!@#$%).
- Optionally exclude ambiguous characters (O, 0, l, 1, I).
- Click "Generate Password" and copy securely to your password manager.
Cryptographic Password Entropy
-
Generated client-side via
crypto.getRandomValues()to ensure high-entropy non-predictability. - A 16-character password using all 4 sets carries ~95 bits of entropy, requiring billions of years to brute-force with modern supercomputers.
Example
-
16-character high-entropy password:
k9#Xm$8P2!vL@7wQ.
Common Applications
- Creating secure master passwords for 1Password, Bitwarden, and Apple Keychain.
- Wi-Fi router WPA3 security keys and server root credentials.
- Financial banking account credentials.
Frequently Asked Questions
Is this password generated on your server?
No! The generator executes 100% locally inside your web browser using native cryptographic APIs. Passwords are never sent across the internet.
What length is recommended for security?
Cybersecurity standards (NIST) recommend a minimum length of 16 characters combining varied character sets.
