So far, logging in and out are a disaster. With face recognition on, when I log out, it logs me right back in. So, if I log out by putting my finger over the camera, turn off face recognition, then log my wife in, it tries to log her in with face recognition of me, even though face recognition is off in her settings, and of course gets an error message. If there are two people in the same household trying to use this app, beware.
