FAQ
Is the password stored anywhere?
No. It’s generated on this device with the browser’s cryptographic random number generator (crypto.getRandomValues) and only shown on screen. Only your settings, like length and character types, are remembered in this browser. Reloading gives you a new password, so copy it into your password manager right away.
How long should my password be?
Strength is based on the “about N bits” estimate: under 40 bits is Weak, under 64 is Fair, under 90 is Strong, and 90 or more is Very strong. The default (16 characters, all four types, look-alikes skipped) is about 101 bits, which is Very strong. You can choose anywhere from 4 to 64 characters.
Will every selected character type actually appear?
Yes. One character from each selected type is placed first, the rest are filled in, and then everything is shuffled. That way the password passes rules like “must include a number and a symbol.”
The site doesn’t accept some symbols.
Symbols are picked from !@#$%^&*()-_=+[]{};:,.?/ and you can’t choose a custom set. If a symbol isn’t allowed, press Regenerate, or turn off Symbols and increase the length to keep it strong.
What does “Skip look-alike characters” do?
It leaves out capital I, lowercase l, the digit 1, the pipe |, capital O, the digit 0, and lowercase o. That helps when you need to read a password aloud or type it from paper. Because fewer characters are available, strength drops slightly.
