About Password Generator
This password generator creates cryptographically random passwords using your browser's Web Crypto API (crypto.getRandomValues). Customize the password length from 4 to 128 characters and choose which character sets to include: lowercase letters, uppercase letters, numbers, and symbols. The strength meter shows the estimated entropy of your password. Generate up to 25 passwords at once for bulk account creation.
Frequently Asked Questions
How secure are these passwords?
Very secure. Passwords are generated using your browser's cryptographic random number generator (crypto.getRandomValues), which provides the same quality of randomness used in TLS/SSL encryption. No passwords are stored or transmitted.
What makes a strong password?
A strong password is at least 12 characters long and uses a mix of lowercase, uppercase, numbers, and symbols. A 16-character password with all character sets has approximately 105 bits of entropy, making it virtually uncrackable by brute force.
Can I generate multiple passwords at once?
Yes. Use the Count dropdown to generate up to 25 passwords at once. Click any password to copy it, or use the Copy All button.
