Ok for day to day... but remember to DISABLE IT BEFORE YOU MOVE DEVICE. I Lost all my android settings after the last android update as it reset my device. No way of getting the codes to log in. Can only verify by text when skipping the initial login  but then settings don't sync ie ringtones  alarms  backgrounds all gone. Also all third party authenticator accounts need to be recreated when you move device.
