🔑 Password Generator

Reused or predictable passwords are one of the most common ways accounts get compromised, and the fix is simple in theory but tedious in practice: a long, random, unique password for every account. This generator creates strong random passwords using a customizable length and character set — uppercase, lowercase, numbers and symbols — plus a live strength indicator so you can see how resistant the result is to guessing.

Everything happens locally in your browser using a cryptographically secure random source; generated passwords are never transmitted or stored anywhere, including by this site.

Length: 16

Lowercase (a–z)

How to use the Password Generator

Set your desired password length using the slider.
Choose which character types to include — uppercase, lowercase, numbers and symbols.
Click generate, check the strength meter, and copy the password with one click.

How password strength is estimated

Password strength here is estimated from entropy — roughly length × log2(character set size) — which measures how many random guesses an attacker would need on average to find the password by brute force. A longer password, or one drawn from a larger character set (adding symbols and mixed case), increases entropy and therefore strength exponentially rather than linearly.

Frequently asked questions

Is it safe to generate passwords online?

This generator creates passwords entirely in your browser using the Web Crypto API's cryptographically secure random number generator — nothing is sent to a server, logged, or stored anywhere, including by this website. The password only ever exists on your device unless you save or share it yourself.

How long should a strong password be?

Longer is generally better: many security guidelines now recommend at least 12–16 characters, mixing uppercase, lowercase, numbers and symbols where the account allows it. Combined with a password manager and unique passwords per site, length is one of the biggest factors in resisting brute-force attacks.

Should I reuse a strong password across multiple accounts?

No — even a very strong password should be unique per account. If one service suffers a data breach, a reused password puts every other account using it at risk too. A password manager makes it practical to keep a different strong password for every account.
