I just switched to Authenticator Pro from Authy and I've been very pleased. It took some time to get my codes transferred over, but now I have android wear support, night mode, and my codes aren't held hostage by Twilio!
We are talking about MOST time, not never. So it is valid argument. It can happen but I would not protect from this, too small chance. But 2FA thing is always useful, so Keepass 2FA is way better solution than do not have it at all 🙂
