Answer:

What is Multi-Factor Authentication?

• Multi-factor authentication (MFA) requires a user to both login with a password and verify their identity through another method. MFA is used to login to a My Sub-Zero Account and Sub-Zero Group Owner's App. A verification code is sent to the user's mobile phone number to verify their identity.
• When a user opts into MFA, they will have to login with a password as well as the code sent to their phone. They can select either an SMS text message or an automated phone call.

Is Multi-Factor Authentication Required?

• Some locations, like Australia, require MFA. For users in other areas, it is an optional layer of extra security. Users can choose to opt in or out during the account creation process.

Can I Remove Multi-Factor Authentication?

• Once MFA has been added to an account, it can only be removed after speaking to a customer care representative. Contact the Sub-Zero Customer Care Team at [email protected], or call (800) 222-7820, Monday-Friday, 7:00 a.m. - 7:00 p.m. CST for assistance.

Can I Add A New Phone Number With Multi-Factor Authentication?

• If an account uses MFA and the phone number needs to be updated, a customer care representative will need to reset it. Contact the Sub-Zero Customer Care Team at [email protected], or call (800) 222-7820, Monday-Friday, 7:00 a.m. - 7:00 p.m. CST for assistance.    

Can I Use More Than One Phone Number for Multi-Factor Authentication?

• An account can only have one phone number set up for MFA. However, this phone number can be different than the phone number on the account. Therefore, it is possible for two different accounts to use the same phone number for MFA, but a single account can only have one MFA phone number.
