It's simple  gets the job done  and I wish more services supported it  this is by far my preferred 2FA solution. In terms of gripes: I'd love for the credentials to be a bit more tightly spaced. If you have a lot of accounts  you may need to scroll. Additionally  it'd be great to have a friendlier way of displaying the codes when logging in through the mobile browser or standalone mobile app. Perhaps make it possible to show select codes on notification bar for a brief time?
