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. 

GMail 2-step Verification - using with SyncBack

To use a Gmail account with SyncBack, where 2-step verification has been inaugurated, you simply need to create and use an application-specific password. To do this, log into your Gmail account using a web browser, then visit the following page for details on how to create an application specific password:

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.

If not using 2-step Verification

You need to configure Gmail to allow access to it from SyncBack:

  • Login to your Gmail account
  • Go to the settings in Gmail (click the gear icon at the top-right and click Settings from the menu)
  • Go to the Forwarding and POP/IMAP settings tab
  • Make sure Enable POP for all mail and Enable IMAP are enabled. Save the changes.
  • You also need to allow access via less secure apps. To do this visit
