The first and most obvious risk from blanket age verification is consent fatigue. The simplest way to put it is this: if you hate cookie consent pop-ups, welcome to the wonderful world of age verification pop-ups. You will be required to prove your age and identity, linked to some official form of identification or via a third party intermediary, on every site you visit and every service you use. (Once you get through that process, then you can move on to cookie consents.)
The second risk is the chilling effect that these blanket age verification processes will have on your digital rights to privacy and freedom of expression. You will no longer be able to read some websites without proving your identity. You will no longer be able to say some things without proving your identity. You will no longer be able to seek certain information without proving your identity. And in the view of some age verification proponents, the only reason you would be opposed to any of that is if you have something to hide.
The third risk comes from the age verification and assurance processes themselves. These processes may collect many different pieces of personally identifiable information in order to profile you to establish your likely age. In doing so, they will create massive privatised databases of personal Internet browsing – databases which would be very appealing to governments or hackers.
