It's great if you plan to never use another phone again. If you do  the option to transfer your authenticator settings to your new device is not there. You have to re-enter each entry manually after you've cancelled it. Problem is many companies require long and time heavy procedures to remove the authenticator verification from your account just so you can reapply it to the authenticator on your new device. Stay away untill they fix the problem.
