How does Rohos Logon Key work?
Rohos Logon Key replaces regular password based logon by USB flash drive (or other removable USB media). The user connects his hardware key to the computer and he/she is logged into Windows without having to type in his/her username or password. It’s just like carrying a key for your house. Imagine that the USB Key is a key to your house, and the computer is your house. In order to get in you have to use the key, otherwise no one can get in unless they forcefully break in.
