When you or a BlackBerry® device user deletes all device data or turns off two-factor authentication, the BlackBerry device turns off two-factor authentication with the installed smart card and permanently deletes the binding information for the smart card from the device.

The device permanently deletes the binding information for the smart card from the NV store in application storage so that a user can authenticate with the device using a new smart card. You can permanently delete the binding information for the smart card from the device by sending the Delete all device data and remove device IT administration command to the device.
