Free Secure Password Generator
Generate cryptographically strong passwords instantly with our free online tool. Perfect for creating secure login credentials, API keys, or any application requiring random strings.
How It Works
Our password generator uses the browser's built-in crypto.getRandomValues() API for cryptographically secure random values. Adjust the slider from 8 to 64 characters and toggle options for uppercase letters, lowercase letters, numbers, and special symbols.
Password Strength Recommendations
- Minimum 12 characters: Modern security standards recommend at least 12 characters
- Mix character types: Combine uppercase, lowercase, numbers, and symbols
- Avoid predictable patterns: Don't use birthdays, names, or common words
- Use unique passwords: Generate a different password for each account
Why Local Generation Matters
Unlike online password generators that may store your generated passwords on servers, our tool runs entirely in your browser. Your passwords never leave your device. We have zero access to what you generate - it's completely private.
Frequently Asked Questions
Q: Is this cryptographically random?
A: Yes, we use the Web Crypto API which provides cryptographically secure random numbers, far superior to Math.random().
Q: Can I use this for my actual accounts?
A: Absolutely. The passwords generated here are suitable for any use case requiring strong, random credentials.
Q: Do you save my passwords?
A: No. Zero logging, zero storage. Everything stays in your browser's memory until you copy it.
Recommended Settings by Use Case
- Personal accounts: Use 16 or more characters with uppercase, lowercase, numbers, and symbols when the site allows them.
- Password manager storage: Use 20 to 32 random characters because you do not need to memorize the result.
- Temporary test credentials: Use shorter values only when the account has no real access and will be deleted quickly.
- Shared team credentials: Avoid sharing passwords in chat. Store them in a password manager or access-management tool.
Security Notes
Random generation is only one part of account security. Use a unique password for every account, turn on multi-factor authentication where available, and rotate passwords if you suspect a leak. Do not paste generated passwords into websites you do not trust, and avoid saving them in plain text files.
Browser Compatibility
The generator relies on crypto.getRandomValues(), which is supported by modern desktop and mobile browsers. If that API is unavailable, a password generator should not silently fall back to weak randomness for real credentials.
