Hi Hans, If the client account enables the "2-Step verification" then the google account of the user who is accessing this account should also be setup for 2-Step verification. In this case, the user on the MCC account who is accessing the client account should have the specific google account setup for 2-Step verification. It is not required to generate a new refresh token. The error TWO_STEP_VERIFICATION_NOT_ENROLLED is expected from V201806 onward if you are using a lower version, you might see a USER_PERMISSION_DENIED error.
Let me know if you have any additional questions.
