I'm a little confused here from the explanation and examples - how is this anonymous exactly? The examples require that you pass their 'changefly user id' and ip address. Both of these are fairly unique identifiers (especially when combined). The mention in the developer documentation that you may prompt them for the user's changefly PIN in the case of an IP address mismatch implies that you are storing the user's IP in some form or another - so basically users are having to trust that you aren't storing information about these 'changefly connections'. This is just one further hop from having the government provide this service themselves, since if they really wanted to, what is stopping them from coming to you and saying 'I want a list of all websites that user at X ip address did age verification on'?
Hey VoidWhisperer, you've raised some excellent and valid points without knowing the underlying technology. It's understandable how the need to pass a an IP address could seem contradictory to the idea of anonymity. IP addresses are required to communicate on the internet whether at home, work, or on the go. Nobody can change that without changing the entire structure of the internet.
Your Changefly ID is anonymous and end-to-end encrypted. Changefly does not know who you are, who you are connecting with, or what your IP address is as we do not log IP addresses.
I encourage you to read more below to learn how the Changefly ID authentication process works and how Changefly is truly changing the game for privacy and security:
