How to use the Password Generator

  1. A strong 16-character password is ready as soon as the page loads.

  4. Aim for Strong or Very strong on the meter, then click Copy and save the password in a password manager.

About this tool

Passwords are generated with the Web Crypto API, your browser's cryptographically secure random number generator, using unbiased sampling so no character is more likely than another. The strength meter measures real randomness (entropy in bits) from both the length and the size of the character pool, not just the length. Nothing is sent to any server, so we never see the passwords you create.

Why use itWeak and reused passwords cause the vast majority of account takeovers. A 16-character random password mixing letters, numbers, and symbols would take centuries to brute-force, yet it is impossible to memorize — which is why security experts recommend a unique generated password for every site, stored in a password manager. Our generator uses your browser's cryptographically secure random number generator, and nothing is ever transmitted or stored, so not even we can see the passwords you create.

Frequently asked questions

Are these passwords truly random?

Yes. We use window.crypto.getRandomValues(), the browser's cryptographically secure generator — far stronger and less predictable than the basic Math.random() used by weak generators.

Is my password sent to your server?

No. Generation happens entirely in your browser. The password is never transmitted, logged, or stored anywhere, by us or anyone else.

What makes a strong password?

Length matters most: at least 12–16 characters mixing uppercase, lowercase, numbers, and symbols — and unique for every single site you use.

Should I use the same password on multiple sites?

Never. If one site suffers a data breach, reused passwords let attackers walk straight into your email, banking, and social accounts. Generate a unique password per site and keep them in a password manager.
