Personally, I use andOTP because: - it's available in F-Droid - it has a PIN The first guarantees that I'll know if they try to sneak something in (they're good at labeling potentially undesirable features), and the second just makes so much sense that I don't know why Google Authenticator doesn't do it (it might now, but it didn't when I last used it). Also, I just like how andOTP looks more than Google Authenticator, but that's entirely subjective. That being said, the fact that andOTP _can_ exist really keeps other apps in line. So even if you don't use an alternative like andOTP, you still benefit from it existing.
