How to Use This Password Generator
Follow these simple steps to create strong, secure passwords.
Choose Settings
Select password length, character types, and number of passwords to generate. Adjust advanced options like exclusions and generation mode.
Generate Password
Click "Generate Password" to create cryptographically secure passwords using your browser's built-in secure random number generator.
Check Strength
Review the password strength indicator. Strong passwords should have high entropy and use multiple character types.
Copy and Use
Copy the generated password with one click or download all passwords to a text file. Use immediately in your accounts.
Password Security Best Practices
Strong passwords are your first line of defense against unauthorized access. A secure password should be long, random, and unique for each account.
This password generator uses your browser's cryptographically secure random number generator (crypto.getRandomValues()) to create truly unpredictable passwords.
Security Guidelines:
- Use passwords at least 12-16 characters long for maximum security
- Never reuse passwords across different accounts
- Enable two-factor authentication (2FA) whenever possible
- Consider using a password manager to store unique passwords
- All generation happens locally - no data is sent to servers
- Change passwords immediately if you suspect compromise
Frequently Asked Questions
How secure are these passwords?
Extremely secure. We use crypto.getRandomValues(), a cryptographically secure random number generator built into modern browsers. This is the same technology used by security professionals and password managers.
Is my data safe?
Yes, 100%. All password generation happens entirely in your browser using JavaScript. No passwords are transmitted to any server. Your generated passwords never leave your device.
What length should I use?
We recommend at least 16 characters for most accounts, 20+ for critical accounts like email or banking, and 12-14 minimum for less sensitive accounts. Longer is always better.
Should I exclude similar characters?
If you need to type the password manually or read it aloud, yes. Otherwise, including all characters provides maximum entropy. Use this option for passwords you'll write down or share verbally.
What's the difference between modes?
Random mode creates maximum security with all character types. Memorable mode uses pronounceable patterns (though still strong). Passphrase mode creates memorable multi-word passwords like "Correct-Horse-Battery-Staple".
Can I trust this generator?
Absolutely. Our code is open-source and uses industry-standard cryptographic APIs. You can inspect the source code yourself. We never store, log, or transmit any generated passwords.
