I run all 4 of my accounts on one monitor/laptop. pass is the same for all accounts with my b.net, and dropdown window on each window has it's own account selected. I use keyclone to fire up all clients first. then type in my password which gets sent to all clients at the same time, click one window at a time and hit enter, then the next x4, then wait for the authenticator window to pop up, then type that 6 digit code in once, then use the mouse to select each window one at a time and hit enter again as before. no copy/paste, no different login codes needed unless i screw up, and no hassle.
