Other's concerns were unfounded Two concerns from others turned out to be non-issues for me. 1. You do not need to install a 3rd-party barcode reader to make this app work because there is an option to confirm your device by just manually typing a code. 2. After installing this app  there are still other ways to get into your account if you lose your phone. Overall I'll agree with others that it's not a fancy app  but if you just want a basic number-generating app  then this should meet your needs.
