Frequently asked questions

Is my password sent to the server?
No. Password analysis happens entirely in your browser using JavaScript. Your password never leaves your device.
What makes a password strong?
Length is the most important factor. A 16+ character password is extremely strong. Add mixed case, numbers and symbols to further increase entropy. Avoid words, names, dates or patterns.
