Frequently asked questions

How secure are these passwords?

They're generated with crypto.getRandomValues, a cryptographically secure RNG, entirely on your device. A 16-character password with all sets enabled has ~100 bits of entropy, far beyond brute-force reach.

Is the password sent anywhere or stored?

No. It exists only on your screen and in your clipboard when you copy it. Refreshing the page destroys it.

What does 'exclude ambiguous' do?

It removes easily-confused characters like I, l, 1, O and 0, useful for passwords someone might read aloud or retype.

What length should I use?

16+ characters for important accounts. Length matters more than complexity. Every extra character multiplies the search space.
