The only place you can find the Mac Address will be on the SWRemote Login screen just above the Device Name, labeled as Code, as seen below.
You can see they match the information below this, from the Admin site
From the login screen you can also determine what your device name is. Although this field is labeled as Mac Address, in one of their previous iOS updates, Apple does not allow us to use the Mac Address anymore. In its place we are using an internal identifier, which should stay the same in most cases, outside of a factory reset.
