Thank you for contacting us. In order to change the main computer setting, you have to open mSecure's Sync Settings on a desktop computer, and check the Main Computer box on Mac or turn on the Main Computer toggle on a PC. After you do that, your other devices will start syncing to the mSecure app on that device.
My data is set to back up via wifi to a computer that has died so I no longer have access to it. I have restored the data to a different computer from an automatic back up but I need to change the main computer to another device. How do I do this?
