You can use M360 on different computers, but not simultaneously. We have a fair computer switch policy that allows you to register 3 different computers, in every 3 months. There is also 48 hours waiting between switching computers. These rules are set, to simply avoid licence sharing between users.
Our policy allows you to change your computer every month in a year, but maximum 3 times in 3 months. You just have to make sure that once you logged in from a new computer, you will wait 48 hours before you try to log in from another machine.
You can monitor the computer count, the current waiting time and the attached computers from your dashboard, on the M360 website what you can access after login. You can also manually detach computers here.
