As far as I recall the device needs to already have your fingerprint scanned and authenticated. So if the device is passed to someone else he'll need to go into settings and update the list of fingerprints. If your OK with any user as long as he's authenticated you can just approve everyone who has a fingerprint on the device. Since the device is already secured by password/fingerprint this should work.
