How this calculator works

Generates strong passwords with a configurable length and character set.

Runs entirely in-browser — nothing is transmitted or stored.

A longer password with a smaller character set is often still stronger than a short one with every character type enabled — length is generally the single biggest factor in how hard a password is to crack.

Example

Set length and toggles for uppercase, lowercase, numbers, and symbols to produce a random secure password.

Frequently asked questions

Is this safe to use?

Yes — generation happens locally with your browser's crypto random source. Nothing leaves your device.

What's a good password length?

16+ characters with mixed types is a strong baseline. Length matters more than complexity for entropy.

Should I use a password manager?

Yes — even the strongest passwords are only useful if unique per account. A manager stores them all encrypted.

Why avoid reusing the same strong password everywhere?

If one site suffers a data breach, a reused password exposes every other account using it — unique passwords per site contain the damage to just the one breached service.
