 TWO_STEP_VERIFICATION_NOT_ENROLLED 

Environment

Connector: Google Ads

Answer

This blog says:

If 2-Step Verification is required for a particular Google Ads account, then 2-Step Verification also needs to be set up for the Google account used to generate the OAuth2 refresh token accessing the Google Ads account. Follow this link to opt in to 2-Step Verification. Failing to do so will result in the AuthorizationError.TWO_STEP_VERIFICATION_NOT_ENROLLED error when you try to access the Google Ads account.

You have to set up 2-step verification for the account with which you are trying to authorize the connector.

Cause

Due to a policy set on administrative users by Google.
