Replace a Multi-factor Authentication Device

A Multi-factor Authentication (MFA) device can be replaced in two ways, depending on whether the previous mobile device is still available and working:

  1. The mobile device is still available and working - The user logs in with MFA and replaces the device in My Account. See My Account - Register New Device.
  2. The mobile device is not available or not functional - The user contacts the CSX administrator outside the CSX system, such as via email or an internal ticketing system, to remove the existing mobile device from the user account. After the administrator has removed the device, the user can register a new mobile device as part of the login process.
