Password Generator: Create Strong Passwords Online
Create strong, unbreakable passwords instantly with our free online password generator. Weak passwords are the #1 cause of account hacks—protect yourself by generating random, secure passwords that are nearly impossible to crack. Our tool uses advanced encryption technology to create passwords that include uppercase letters, lowercase letters, numbers, and symbols.
Customize your password length from 8 to 128 characters and choose which characters to include. See real-time password strength ratings as you adjust settings. Everything happens securely in your browser—your passwords never touch our servers or get stored anywhere. Generate a password, copy it, and use it immediately for any account.

Frequently Asked Questions
How does this password generator work? +
This tool uses your browser's built-in cryptographic random number generator (crypto.getRandomValues) to create truly random passwords. Your passwords are generated entirely in your browser and never sent to any server, ensuring maximum security and privacy.
What makes a password strong? +
A strong password has high entropy, meaning it's unpredictable and hard to guess. Key factors include length (16+ characters recommended), character variety (uppercase, lowercase, numbers, symbols), and randomness. Our tool calculates entropy in bits - aim for 80+ bits for important accounts.
Is it safe to use an online password generator? +
Yes, when using a client-side generator like ours. Everything runs in your browser using JavaScript - no passwords are transmitted or stored. You can verify this by disconnecting from the internet and the tool still works. Always use HTTPS and avoid generators that require server communication.
How long should my password be? +
For most accounts, 16 characters minimum is recommended. For high-security accounts (banking, email, password managers), use 20-24+ characters. Each additional character exponentially increases the time needed to crack the password through brute force.
Should I use a password manager? +
Absolutely. Password managers let you use unique, strong passwords for every account without memorizing them. Generate a strong password here, then store it in a reputable password manager like Bitwarden, 1Password, or KeePass. Use a memorable but strong master password for the manager itself.
