Nice writeup. As a belgian, I do not think I know anyone or any apllication that uses you eID pin. I know you have to create one at the municipality when you collect your id card, but I doubt anyone would ever remember it. ItsMe has universally replaced all scenarios that would have needed an eID with pin, and booting the ItsMe account, while I think you in theory could do it with an eID and reader, I do not think anyone does. I know I have such a reader from a developer conference decades ago from when eID was lauched. Not sure it would even work on 2026 OS'es.
