I am using the Google Admin SDK APIs to manage users (create/update) in our organization's Google apps account. We allow users to optionally use the 2-factor authentication feature and I'd like to be able to determine if an account has it enabled or not when one of our internal support reps looks up their account. Looking over the docs at https://developers.google.com/admin-sdk/directory/v1/reference/users, I do not see any attributes that would indicate this setting.
Is there another way for me to check if it is enabled via an API?
