Information for transferring contents of a Google Drive.
Guest Accounts will be required to enable G2SV and will need to be linked to one phone number (cell or office number) in order to initially enable. Use these instructions to enable authenticator for multiple users.
Google Takeout allows you to easily transfer Gmail and Google Drive data through an automated process. This process will transfer Gmail labels/folders and keeps Google Drive in your current folder structure.
Once G2SV is setup on a Guest Account that is accessed by multiple people, each user approved to access that account will need to setup the Google Authenticator app on their mobile device (Android or iOS).
