Generate a strong random password

Use this free online password generator to create strong, secure, truly random passwords in seconds. Pick the password length with the slider and choose exactly which character sets to include — uppercase letters, lowercase letters, digits and symbols — then optionally exclude look-alike characters for easier typing. Every password is built locally with crypto.getRandomValues, the browser's cryptographically secure random source, never the predictable Math.random. Because this random password generator runs 100% in your browser, nothing is ever uploaded and your password stays completely private. Copy your new secure password with one click and use it for any account, Wi-Fi network or app.

Frequently asked questions

Are these passwords really random and secure?

Yes. Each password is built with crypto.getRandomValues, the browser's cryptographically secure random number generator, using reject sampling to avoid bias — never the predictable Math.random — so the output is genuinely unpredictable.

Is my password uploaded or sent anywhere?

No. The generator runs 100% in your browser, so your password is created entirely on your device and never leaves it. Nothing is uploaded to any server, keeping it completely private.

How long can the password be?

You can choose any length from 4 to 64 characters using the slider. Longer passwords with more character types give you a much stronger result, as shown by the strength rating.

What characters can I include?

You can mix uppercase letters (A–Z), lowercase letters (a–z), digits (0–9) and symbols (such as !@#$%^&*). Enable at least one set to generate a password.

What does 'exclude ambiguous characters' do?

It removes easily confused look-alikes such as O, 0, l, 1, I and similar symbols, so the password is easier to read and type without meaningfully weakening it.

How is password strength calculated?

The strength rating estimates entropy in bits from the length and the size of the character pool you selected, labeling the result Weak, Fair, Strong or Very strong.
