What is Login Reporting?
Reporting is a tool that lets Enterprise Administrators monitor what URL's their Enterprise users are using LastPass to login to. This tool lets Administrators ensure that users are not misusing the LastPass Enterprise system for unathorized access to certain sites. There are several reporting modes from which you can choose. These range from no reporting whatsoever, to the ability to see every site to which the user has logged in, along with the time and date of the login. To view these options click on the 'What is this?' link next to REPORTING MODE.
