Password Generator
Generate strong, random passwords instantly. Nothing is ever stored or sent anywhere.
Why Use a Strong Password Generator?
Weak passwords are one of the most common causes of account breaches. A strong password generator removes human bias — people tend to choose predictable patterns, words, or dates. This tool uses your browser's Web Crypto API to generate cryptographically random passwords that are computationally infeasible to crack.
How Password Strength Is Calculated
Password strength depends on two factors: length and character set size. A 16-character password using uppercase, lowercase, numbers, and symbols has over 7 quadrillion possible combinations. Adding more characters multiplies this exponentially. The strength indicator above shows how your current settings stack up.
Best Practices for Password Security
Generate a unique password for every account — never reuse passwords. Store them in a trusted password manager (Bitwarden, 1Password, or your browser's built-in vault) so you only need to remember one strong master password. Enable two-factor authentication wherever available for an extra layer of protection.
Frequently Asked Questions
How long should a password be?
Security experts recommend a minimum of 12–16 characters for most accounts. For high-value accounts like banking or email, 20+ characters is ideal. Longer passwords are exponentially harder to crack via brute force, regardless of the character set used.
What makes a password strong?
A strong password is long (16+ characters), random, and uses a mix of uppercase letters, lowercase letters, numbers, and symbols. Avoid dictionary words, names, or predictable patterns like "123" or "abc". Random generation is far more effective than human-chosen passwords.
Is it safe to use an online password generator?
This generator runs entirely in your browser using the Web Crypto API — no passwords are sent to any server or stored anywhere. The generation is cryptographically secure, meaning the randomness is suitable for security-sensitive use.
Should I use a password manager?
Yes. A password manager lets you use a unique, strong password for every account without memorizing them. Generate a strong password here, then store it in Bitwarden, 1Password, or your browser's built-in vault. You only need to remember one strong master password.
