Version 7 has a profile feature that allows multiple local sets of RoboForm data on the same machine (found by clicking the RoboForm icon >> Tools >> Profiles). Any authorized user of the computer can switch between profiles. However, the Master Password must be entered to view the contents of protected files and use them to fill forms or log in to sites.
Version 8 substitutes multiple RoboForm profiles with multiple RoboForm accounts. Switching between RoboForm accounts requires logging in and out with the corresponding account.
