I've just signed up to the equivalent in the uk called government gateway

you have to provide information and details from two of the following: Passport, last tax submission or driving licence

the sign up to the internet healthcare system used by my doctor seemed to be run by a 3rd party (not happy) needed general information and a picture of my passport or driving license. I declined, because it's a third party and I could not be bothered reading the large list of ways they will likely sell your data and partially because I don't need my doctors info online
