Password Generator

Password Generator creates strong, random passwords using your browser's cryptographically secure random number generator. Choose the length and which character types to include, then copy the result straight into your password manager.

Passwords are generated entirely on your device and are never transmitted or stored, so what you generate stays private to you.

How to use Password Generator

  1. 1

    Set the length

    Drag the slider to choose a length. Longer passwords are exponentially harder to crack.

  2. 2

    Choose character types

    Toggle lowercase, uppercase, numbers and symbols to match each site's requirements.

  3. 3

    Copy and save

    Click Copy and paste the password into your password manager or the sign-up form.

What makes a password strong

Password strength comes from length and unpredictability. A 16-character password drawn from a large character set has so many possible combinations that brute-force guessing is impractical, even for powerful hardware.

Mixing uppercase, lowercase, numbers and symbols increases the pool of possible characters per position, multiplying the total number of combinations. Aim for at least 16 characters and use a unique password for every account.

Why generate passwords locally

This generator uses the Web Crypto API (crypto.getRandomValues), which produces cryptographically secure random values suitable for security purposes — unlike Math.random(), which is predictable.

Because generation runs in your browser with no network request, the password is never seen by any server. The safest place to store it afterward is a dedicated password manager.

Frequently asked questions

Are the passwords truly random?
Yes. They are generated with the Web Crypto API, which is designed for cryptographic use and avoids the bias and predictability of ordinary random functions.
Is it safe to generate passwords on a website?
This tool runs locally in your browser and makes no network calls during generation, so your password is never sent anywhere.
How long should my password be?
At least 16 characters is a strong baseline. For high-value accounts, go longer and enable all character types.
