Cryptographically Secure
Uses the Web Crypto API for true random number generation, ensuring maximum security.
Customizable Options
Choose password length (8-64 characters) and character sets (uppercase, lowercase, numbers, symbols).
Strength Indicator
Visual password strength meter helps you understand how secure your generated password is.
Privacy First
All passwords are generated locally in your browser. Nothing is sent to any server.
Why Strong Passwords Matter
Weak passwords are one of the most common causes of security breaches. A strong password should be:
- At least 12-16 characters long
- A mix of uppercase and lowercase letters
- Include numbers and special symbols
- Unique for each account (never reused)
- Random, not based on personal information
tools.common.faq
How secure are these passwords?
Very secure. We use the Web Crypto API's getRandomValues() function, which provides cryptographically strong random values. This is the same level of randomness used in security-critical applications.
Is my password stored anywhere?
No. All password generation happens entirely in your browser. We never see, store, or transmit your passwords.
What password length should I use?
We recommend at least 16 characters for important accounts. Longer passwords are exponentially harder to crack. For maximum security, use 20+ characters with all character types enabled.
Should I use a password manager?
Absolutely! Password managers allow you to use unique, strong passwords for every account without needing to remember them. This is one of the best things you can do for your online security.
