In the future, you can also revoke other trusted devices from any trusted device.
removeTrustedDevicein the view controller will make a request to remove the current device as a trusted device. If the request is successful, no error will exist, and a text label will be populated to let the user know whether the removal succeeded or failed. Otherwise, if desired, the user can also perform a segue to another view controller (on success or failure) in the callback function as well.
You cannot remove the last Trusted Device. You will need to have 1 remaining Trusted Device.
