Switzerland narrowly approves plan for digital ID

No, it’s not always centralized, and even when it is, it is not as centralized as it is now.
When a digital ID requires more information about you than a physical ID or a non-biometric ID, that’s more surveillance into your life.

Where does it require more information than what is already there? And what information?

No. Enlighten me.

An IDP (Identity Provider) is a service with which you can authenticate and authorize you for things.
For example one IDP would be a Domain Controller from the Microsoft ecosystem in companies. Another IDP would be Google (you know the “login with Google" button for SSO logins).
Another IDP would be Authentik/Authalia maybe a bit better known in the self-hosting community.

A IDP is a management for the IAM principal and if you look through this whole E-ID thing (Swiss, Austria, Germany, and EU [EU-ID/E-ID]).
It’s nothing more or less than a normal IDP, it just manages the Identity, Authentication, Authorization for government portals and services.

The EU has national ID cards for EU residents that they can use to travel within the EU. Most EU countries have it as an option, but some don’t.

I think we speak both about the EU-ID/E-ID. So yeah

I think @Onscreen5341 believes that most people would be comfortable sending a photo of their physical ID to a website in order to access it, and hence, to them, it’s the same with a digital ID.

Where did I say that? I said between age verification with a normal ID and a digital one are not where many differences.
I generally don’t like age verification and reject it, but if you have age verification with a normal ID or a digital one it is indifferent.

If you don’t see anything wrong with digital IDs, I check out the work of Big Brother Watch. They are a non-profit UK organization that fights for privacy, and have been at the forefront of the National/Digital ID issue.

Did you watch the video, because I highly doubt this at this point. They don’t criticize the E-ID, they criticize that it is mandatory, and the government forces them to, and they criticize that the government has no clue what they’re actually doing. And I share the same thoughts about this. The forcing on people is not good, but as long as it is optional it is a good thing.
Also, we should acknowledge that people that got interviewed thought that the government hadn’t all the information already which isn’t true for the UK, they already had the digital data.
See @qofwzndsfh his comment, about how it went.
