When enabled, during OAuth2 authentication, Google prompts users for 2SV before issuing a refresh token. Pre-existing refresh tokens remain valid unless 2SV is required. If 2SV is required and a pre-existing refresh token is used, the \"TWO_STEP_VERIFICATION_NOT_ENROLLED\" error occurs. The solution is to enable 2SV in the user's Google account and then repeat the OAuth2 flow to generate a new valid refresh token.\n"],null,[]]
