Authentication makes sure you're the only one managing your Android devices
Android Device Manager — the Android service to help find, track and wipe a missing phone or tablet — had its app updated today, and there's just one small change. You can now set things up so you'll need to supply your Google password when opening the app or switching accounts.
This seems like a minor change, and one that's hardly newsworthy, but it makes a very big difference — no longer can someone pick up your phone and erase another device on your account without knowing your Google credentials. Granted, they can still do some very ugly things with the phone in their hands, but now your tablet or back-up phone is off-limits to friends, lovers or creepy dudes at the office.
