One of my friends does this with his long-term girlfriend. I think they're at something like a 3 year streak at this point. They've exchanged username/password credentials to keep the streak alive in the event one of them forgets or my friend messes up his phone so badly he can't get it to boot. He's very enthusiastic about custom ROMs on Android so bricking his phone is not out of the ordinary.

edit: he says they've done that at least twice
