The UK already has (various) digital IDs but this is the 'new' one https://www.gov.uk/using-your-gov-uk-one-login. So what's going to be different? Just making it mandatory?

I can see some justification (sorta) for not making it mandatory, but saying it won't improve citizens lives is complete rubbish. Having one login for all government services would massively improve the efficiency, especially if other departments can share data (with consent ala oauth) with each other. Even in the NHS itself this would be a huge boon, if you get referred to two different NHS trusts they basically cannot see any other data. If all medical records could be linked to an ID (that is more sophisticated access control wise than the NHS number) it would actually be a huge boon for privacy/audit/logging.

Government website login isn't really a 'digital ID' is it? I've never thought of it like that anyway - could be used as one, maybe, but it isn't currently. E.g. you say this would help the NHS - well gov.uk login isn't any different from NHS app login is it? So the NHS already has 'digital ID' too.

(Don't expect this to solve multi-computer-system NHS though, ha! That's been tried and failed how many times, for how many billions? At least we have the app now, such as it is, I suppose.)

Brazil has a similar system (gov.br), which provides access to almost everything you might need from the government, including notary services, public healthcare records, driver's licenses, consulate services abroad, income tax, social security, unemployment benefits, welfare benefits, and more.

I also understand the privacy argument that arises from consolidating all these systems, and I'm generally pro-privacy, including in some extreme cases. However, this service makes life so much easier across many dimensions of daily life, and I think it's worth it. I can only hope that the GOV.UK login achieves a fraction of this.

One Login is an "authentication" system, an oAuth provider with identity added on. This means you can prove your identity once (to various levels of confidence, as defined in GPG45 [1]), and use that same verification across different government services.

When people talk about a national ID system, they're often talking about some form of "authorization", i.e. proving that you are entitled to certain things.

There currently isn't a system in the UK that can definitively prove that you have access to every service. For example, even being a British citizen and having a British passport doesn't automatically entitle you to access the NHS.

I'm quite surprised that's not a thing over there

In Poland you can log in into governmental services platform by: scanning QR code with a digital id app (requires authorizing it beforehand but once it's done it works like a charm), a separated national id card app - only for newer documents with rfid chip, 3rd-party login via bank (as long you pick bank that offers it - some smaller ones don't), a qualified digital certificate within yet another app. There should be another option for EU citizens who in theory would use their national SSO platform as a provider but seems it doesn't work right now.

That digital id app will likely integrate everything else since it already provides a way to secure your national id number (a SSN equivalent) and driving license, health services (doubling the functionality) and train tickets components.

A separated health service app is also available where you can manage prescriptions for medicines, referrals for tests and vaccinations.

How would this solve the disparate NHS systems issue? The NHS id exists and is used by all of them. It's the various systems with no central data repository that is the problem. Throw in the fact that Scotland and NI have completely separate NHS's again and I don't see how another id ever solves it. The solution is bringing the NHS in all regions into the 21st century - which costs money they don't have.

The already tried one login for all government services (Government Gateway Id), but they released it when all the services had their own tech teams and it was a general disaster.

Each service would issue you a different one.

It's not so bad now, but it's extremely irritating to have a number as the user id as when you run a business or two, you end up with more, and then you have no idea which is which.
