Frequently asked questions

Is the generated password sent or stored anywhere?

No. It comes from your browser's cryptographically secure random generator and exists only on your screen until you copy it. Nothing is logged — there is no server.

How long should a password be?

Aim for at least 80 bits of entropy — the meter shows the math live. With letters, digits, and symbols, 14+ characters gets you there; longer is always better.

What does "exclude ambiguous" do?

It removes lookalike characters (0/O, 1/l/I, |) so the password survives being read aloud or retyped from paper.
