Password Generator
Generate strong, secure passwords with customizable length and character types. Bulk generate and check password strength.
How It Works
This generator creates cryptographically random passwords using your browser's built-in crypto API (window.crypto.getRandomValues). This is the same randomness source used by security applications. Choose your password length (8-128 characters) and which character types to include: uppercase letters, lowercase letters, numbers, and special symbols. The strength meter evaluates based on length, character variety, and entropy.
Frequently Asked Questions
How secure are these passwords?
Very secure. Passwords are generated using the Web Crypto API (cryptographically secure random number generator). A 16-character password with all character types has approximately 105 bits of entropy — it would take billions of years to crack with current technology.
Are my passwords stored anywhere?
No. Passwords are generated entirely in your browser and never sent to any server. We have no way to see or recover your generated passwords.
How long should my password be?
At minimum 12 characters, ideally 16+. Each additional character exponentially increases security. For critical accounts (banking, email), use 20+ characters with all character types.
Should I use a password manager?
Yes! A password manager lets you use a unique, strong password for every account. You only need to remember one master password. Popular options include Bitwarden (free), 1Password, and KeePass.
