Italy doesn't have crypto keys (as the average person would just lose/leak them) but they offer SSO login with the ID card. Basically whenever you need to verify your identity you pick "sign in with CIEid", you get redirected to a goverment website where you can authenticate (typically by scanning a qr code + scanning your physical id card on your phone) and then you approve/deny the authentication request (you can also clearly see which data is shared (name, last name, dob, etc)). it's stupid easy to setup, the app is not overly bloated and it has different options to authenticate.
