Google Security restrictions
In 2019, Google implemented restrictions on 3rd party software and services accessing Gmail. Although 2BrightSparks contacted Google to not have SyncBack restricted, unfortunately we were denied. This means that in July 2019 the OAUTH2 access method (implemented in SyncBack V8) will stop working. To get around this you will need to use the application password method described below.
On 30th May 2022, Google also stopped 3rd party software and services accessing Gmail that use your login credentials. You must use the the application-specific password method described below.

You then simply use the provided application-specific password in SyncBack (instead of the password you would use to log in to Gmail) with your normal Gmail address for the account in question.
