About Password Generator
The Password Generator creates cryptographically secure passwords using your browser's Web Crypto API. Configure length and character types to meet any security policy or website requirement.
Each generated password is built to include at least one character from every selected set (uppercase/lowercase/number/symbol), then shuffled for stronger composition.
Need passwords in bulk? Set the count to generate up to 50 unique passwords at once — each with its own strength indicator. Perfect for provisioning accounts, resetting credentials, or generating tokens.
Strong, unique passwords are the first line of defense for your online accounts. This tool helps you create unpredictable passwords that resist brute-force and dictionary attacks. Everything runs locally — no passwords are ever transmitted or stored.
Frequently Asked Questions
Are the passwords truly random?
Yes. Passwords are generated using the Web Crypto API (crypto.getRandomValues), which provides cryptographically secure random values — far stronger than Math.random() and suitable for security-sensitive applications.
What is a good password length?
Security experts recommend at least 12–16 characters for standard accounts. For high-value accounts (banking, email, work), use 20+ characters with all character types enabled. Longer passwords exponentially increase the time required to crack them by brute force.
How can I remember a complex randomly generated password?
You should not try to memorize randomly generated passwords — use a password manager (Bitwarden, 1Password, LastPass) to store them securely. The manager generates and fills passwords for you, so you only need to remember one master password.
Can I generate a password that meets specific site requirements?
Yes. Toggle the character sets to match the site's requirements. If a site requires at least one uppercase, one lowercase, one number, and one symbol, enable all four sets. Adjust the length slider to meet the minimum and maximum requirements.
Should I use a different password for every account?
Absolutely. If one site is breached and you reuse passwords, attackers use credential stuffing to access your other accounts. Use this generator to create a unique password for each service and store them all in a password manager.
What does the strength meter measure?
The strength meter estimates strength based on length and character-set diversity (how many different types — uppercase, lowercase, numbers, symbols — are included). It is a practical indicator of complexity, not a formal crack-time guarantee.
Are generated passwords stored anywhere?
No. Passwords are generated entirely in your browser and never transmitted to any server. Once you navigate away or refresh the page, they are gone permanently.
