Just to clarify, eIDAS is an EU regulation (https://en.wikipedia.org/wiki/EIDAS). Regulation means it's law in all EU member states.
Organisations can implement eIDAS-conforming technology to provide eID services if they get certified; e.g. our company provides such services (remote onboarding without video conference need + qualified electronic signature signing): https://www.zealid.com/en/
> Also judging by dealing with the average citizen on a daily basis, even securing an iOS device and remembering the iCloud password is beyond their level of care.
The EU digital ID is based on EIDAS, a technology that is already in use by banks in the entire EU. You can be sure it is safe, otherwise any bank in the EU would have been hacked already.
