Enterprise Server and the BlackBerry device).

Unbinding the smart card from the BlackBerry device

When the BlackBerry Enterprise Server administrator or the user starts a BlackBerry device wipe, causing the

BlackBerry device to erase its stored user and application data, the BlackBerry device permanently deletes the

smart card binding information from the NV store so that a user can authenticate with the BlackBerry device

using a new smart card.

The BlackBerry Enterprise Server administrator can permanently delete the smart card binding information from

the BlackBerry device manually in the following ways.

• Send the Erase Data and Disable Handheld IT administration command to the BlackBerry device to

permanently delete the binding between a user’s current smart card and the BlackBerry device.

• When the user turns off two-factor authentication, the BlackBerry device turns off two-factor authentication

with the installed smart card and permanently deletes the smart card binding information from the

BlackBerry device.
