In our product, the term "traditional login account" means login handling by our application rather than the typical web app "login" or Windows login. Our users are operating a commercial ink-jet printer, and no one wants to stop printing just because of a shift change. We've had to create our own user management scheme with user rights, passwords, etc.
For those of you shrieking in horror at the idea of a roll-your-own user system, it works well enough.
We distinguish users through the position of the device on the aircraft they are working on.
E.g. if device is in 'pilot' slot, you get pilot view. If device is in co-pilot slot, co-pilot application will be launched instead. So each device has to have all the applications for all the positions of the aircraft loaded.
