Has anybody done ID-card or Mobile-ID logins for IPB before?

In Estonia it's common that companies let you authenticate yourself with an ID-card or Mobile-ID. Then you can be certain theres a human behind every account. But it's not an add-on, every company have developed their own system. Have anybody done such system or are familiar with it? So far I have only seen platforms other than IPB using this kind of authentication. Is it hard to achieve in VS? Found some instructions here: http://id.ee/index.php?id=35748

Thanks!

I've not personally seen this done before. It seems like it would be tedious if you had to do this for each provider separately.
