Setting up Spacetop requires a Google account, but if you want to switch between Google accounts that is certainly an option.
The need to access other accounts could arise if you would like to have access to both your work and personal email, or if you have multiple people using one Spacetop.
While the main Google account must remain connected to Spacetop (disconnecting your account amounts to a factory reset), you are free to switch between Google accounts within the Gmail and Google workspace apps.
To access other accounts follow the steps below:
1) Open the Gmail app.
2) Click on the icon for your account on the upper right hand corner of the screen.
3) Click the "Add another account" button
4) Sign into your other Google account
It is important to note that each window is a unique instance that relates to a Google account. This means that changing the Google account for one window will not affect any other windows.
Now you can access your other account. It is possible to add more accounts as needed to the app.
