The ID card also has this amazing function where you can log in to sites using the card without revealing your identity, and even merging the databases from two sites does not allow two users to be identified as the same natural person: https://www.personalausweisportal.de/Webs/PA/EN/business/tec...

I have never seen a website offering login using this function, though ;-)
