We have started auditing our users and deleting them if they haven't logged in for more than 2 years. However, many users are actively using their google account on their mobile devices and haven't actually logged in for an extended amount of time.
The GET user endpoint has "lastLoginTime" but that is not updated unless an actual login occurs. https://developers.google.com/admin-sdk/directory/reference/rest/v1/users/get
How can we determine if a user is still actively using their google account when they haven't logged in for an extended amount of time?
I reviewed different API endpoints and tried searching for a solution. I couldn't find anything.
