this is not big news in dk, it will be up again soon - i dont know of any mitid services that are life-or-death enough to have people panicing about an hours downtime

>this is not big news in dk

Yep let's not learn from that incident and wait until is offline for like 2 weeks, and be assured that will happen.

The Swedish BankID has the same potential weak point. Any centralised system does. The way TLS on the Web works is better: as long as the CA is up some time during the period I need to renew it is fine. Digital IDs should really work that way (probably with relatively short life spans just like let's encrypt: the digital ID could need to be renewed once a week for example, and it would opportunisticly renew when less…

For anything as high stakes as eID you need real-time revocation checks, which brings you back to at least some level of centralization.

Sure... but it should degrade to work when the central services are down.

You should still be able to authenticate with each individual service when the centralised service is down.

There is no reason why you shouldn't be able to login to your bank under these circumstances.

These things should be offline / resilient first right? Smartcards / YubiKeys. Never understood the logic for these to be centralised / online.

Revocation.

can be solved with a hybrid model that degrades when the central service is down. No?

First, we saw Russian hacking campaigns in Ukraine before the invasion of the country. [1][2] Are we seeing the same in Denmark/Greenland with the USA? [1] https://www.europarl.europa.eu/RegData/etudes/BRIE/2022/7335... [2] https://en.wikipedia.org/wiki/2022_Ukraine_cyberattacks

Should have stuck with NemID a previous paper alternative or only offered MitID as a digital alternative. The rush to go all digital is coming back to bite them in the .....

How would you use a paper ID online? (Securely, i.e. not the insane thing of taking a selfie holding it or something similarly bizarre in an age of powerful GenAI.)

NemID, the previous national 2-factor solution, used a small card with rows of pre-printed single-use codes. When you logged in to a bank or a public sector website, it would ask for a random code at a specific row and column number. Once the system registered that you had just a handful of codes left, a new card would be sent to you via snailmail. It worked fine for the time.

The current system, MitID, depends on smartphones, though you can get an an external key generator as a backup too.

Don't banks have their own id:s as well? At least in another nordic country, you have quite many login possibilities to many services. Banks even provide cross-login.

As I understand it, BankID in Sweden is still run by one organisation co-owned by the big banks, and banks handle verification for issuance. There is still a single point of failure for the operation of the system.

Same in Norway.

I don't understand. We don't have real time revocation for passports, do we?

In fact, we don't have real time revocation of any document until very recently...

PKI works offline until you realize you need to handle revocations.

For this and related reasons, such as enforcing protocol upgrades, most smartcard systems end up permanently online.

Italy's digital ID (SPID) works by having multiple trusted providers that can attest your identity. You can sign up with multiple of them, and if one is not available you could use another one. Not perfect (it's still centralized in the hand of 10-20 providers) but better than nothing. Unfortunately most people only ever signed up with one provider, and the government is now pushing for a more centralized digital ID istead (CieID).
