This is the future those who push for age verification want for us.

@Gargron In denmark, Datastyrelsen (the state office caring for data) released an "altID" app, which can be used as an ID, IRL or online. After creation, data stays on your device, and what clients get is an age or identity verification, and you get to choose what to share. They failed to make it open source, but given it does what the say it does, it at least better than scanning passports etc, I believe. It is derived from an EU model afaik. And I was able to install it on my google-free /e/os fairphone. FWIW.

In NL we have @yivi_privacybydesign, which is even on F-Droid. I've yet to encounter something that uses it (so it's not on my phone anymore), but I'm happy we have something decent ready in case age verification becomes mandatory.
@Gargron
@kainisenni @yivi_privacybydesign @Gargron Yes, yivi. In Denmark, the app is prepared for buying alcohol, tobacco and such, and can display a QR code (confirming that you are old enough) that can be scanned in stores, for example. I havent tried to use it yet, it will take some time I believe :)
