RESET_PASSWORD
We log this when the admin forces a new password for the
device or the managed profile.
There is no log data (only the event).

RESET_PASSWORD_WITH_TOKEN
We log this when the admin forces a new password for the
device or the managed profile. The admin can change the
password even before the device is unlocked, as long as the
password reset token was previously provisioned.
