Details are really important. That doesn't mean I could possibly handle every single detail myself, I can't. We have a whole team that handles different parts of the system and they are fully qualified. In fact the engineers doing this feature did write the correct implementation. I simply made a mistake answering the question.

I think people are confusing the Authy Google Authenticator Support with the Authy product.

We do not sell Google Authenticator or aim to be a replacement for it. We simply added the possibility to add Google Authenticator tokens into the Authy App - mostly since our existing clients wanted this -.

Our Service, it's usage etc are completely separate.. If you are not using Authy you can simply use Google Authenticator App.

The only thing in common is we both use RFC 6238 which is an open standard for Time based OTP's.
