The Password Generator creates strong, cryptographically secure passwords instantly in your browser. Using your device's built-in random number generator (crypto.getRandomValues), every password is truly random and unpredictable. Customize the length from 4 to 128 characters, choose which character types to include (uppercase, lowercase, numbers, symbols), and generate multiple passwords at once. This tool is essential for anyone creating accounts, managing credentials, or improving their online security. No passwords are stored, transmitted, or logged - everything happens locally.
Use the slider to choose your desired password length, from 4 to 128 characters. Security experts recommend at least 12 characters for strong passwords, and 16+ characters for critical accounts like banking and email. Longer passwords are exponentially harder to crack.
Toggle the character types to include: uppercase letters (A-Z), lowercase letters (a-z), numbers (0-9), and symbols (!@#$%^&*). Including all four types creates the strongest passwords. If a service doesn't allow symbols, you can uncheck that option.
Press the Generate button to create your password(s) using cryptographically secure randomness. The strength meter will show whether your password is weak, medium, or strong based on its length and character variety.
Click the copy button next to any generated password to copy it to your clipboard. If you generated multiple passwords, use the 'Copy All' button to copy them all at once, separated by line breaks. Store your passwords in a password manager for safekeeping.
This tool uses the Web Crypto API (crypto.getRandomValues), which provides cryptographically strong random numbers sourced from your device's hardware random number generator. This is fundamentally different from Math.random(), which uses a predictable algorithm. The result is passwords that are truly random and cannot be predicted or reproduced.
Yes, when the generator runs entirely in your browser like this one does. No passwords are sent to any server, stored in any database, or transmitted over the network. You can verify this by checking your browser's network tab - no requests are made when passwords are generated. For maximum security, you can even use this tool while offline.
Security experts recommend a minimum of 12 characters for everyday accounts and 16+ characters for high-security accounts (banking, email, password managers). Each additional character exponentially increases the number of possible combinations. A 16-character password with all character types has over 10^30 possible combinations, making brute-force attacks practically impossible.
Including symbols significantly strengthens your password by increasing the character pool from 62 (letters + numbers) to 95+ characters. However, some services restrict which special characters are allowed. If you encounter issues, try generating a password with only letters and numbers, which is still strong at sufficient length (16+ characters).
Modern security guidance from NIST (National Institute of Standards and Technology) recommends against routine password changes unless there's evidence of compromise. Instead, focus on using unique, strong passwords for every account and enabling two-factor authentication wherever possible. Use a password manager to store and organize your credentials securely.
