# MFAOptionType


 *This data type is no longer supported.* Applies only to SMS multi-factor authentication (MFA) configurations. Does not apply to time-based one-time password (TOTP) software token MFA configurations.

To set either type of MFA configuration, use the [AdminSetUserMFAPreference](API_AdminSetUserMFAPreference.md) or [SetUserMFAPreference](API_SetUserMFAPreference.md) actions.

To look up information about either type of MFA configuration, use the [AdminGetUser:UserMFASettingList](API_AdminGetUser.md#CognitoUserPools-AdminGetUser-response-UserMFASettingList) or [GetUser:UserMFASettingList](API_GetUser.md#CognitoUserPools-GetUser-response-UserMFASettingList) responses.
