Thanks for your reply. As I just purchased your product which is mainly for my android, I am evaluating whether it is safe if I store one Enpass copy in my notebook which I will also bring along outside. I find out that there is 3rd party win apps on market for resetting a PC password or to unlock a windows PC. Then I think after the notebook being gained control by the one who got this notebook, he could gain full admin right to change the password and also the win Hello authority, say adding his own biometrics. In that case, could he directly gain access to open the Enpass content by biometrics without a need to use a master password to unlock the Enpass.
