Random Password Generator
Generate strong, uncrackable passwords using cryptographically secure random number generation. Zero server logging.
Password Security Best Practices
16+ Characters
Length is the most significant factor in brute-force resistance. Passwords with 16+ chars take centuries to crack.
Diverse Characters
Combine uppercase letters, lowercase letters, numbers, and special symbols to maximize entropy bit strength.
Unique Per Service
Never reuse the same password across multiple accounts. Store generated passwords in a reputable password manager.
Frequently Asked Questions
Are the generated passwords sent to your server?
No! All random characters are created locally on your computer or phone using `window.crypto.getRandomValues()`. They are never sent across the internet.
What is entropy in password strength?
Entropy measures the randomness and unpredictability of a password in bits. A password with >80 bits of entropy cannot be cracked by modern supercomputers.
