aqtinstall VS IdentityServer

I've used aqt[1] before but it doesn't look like it's seeing 5.15.11 yet, just 5.15.2.

Don't use the Qt installer. It sucks. It's only reason is to annoy people and collect your data. Use aqt: https://github.com/miurahr/aqtinstall

I mostly disagree. Like you said, Qt is the best native GUI toolkit available today. And that is a hard achievement. There are many tradeoffs (some you pointed out) but the open source community seems to find a way around those limitations. There are thousands of open source libraries you can plug-in into your Qt app to overcome many of its limitations (although some remain, like how can't we still not easily change caret/cursor color of QTextEdit??).

Unlike you, I like the direction where Qt is taking. I think QML and Qt Quick are great. I just implemented a feature in my note-taking app that turns Markdown text into Kanban board using QML and the experience has been great (https://github.com/nuttyartist/notes/pull/574). I'm planning to continue transition from QWidgets to QML/Qt Quick.

I do worry of the continuous friction with open source development and hate the online installers as well. I can recommend this useful tool https://github.com/miurahr/aqtinstall that allows you to easily download prebuilt Qt binaries. I hope they can revert their approach on that.

Install the qt binaries from the command line https://github.com/miurahr/aqtinstall

https://github.com/miurahr/aqtinstall will help you with that.

you can install it from vcpkg or conan (or https://github.com/miurahr/aqtinstall if you really want the official Qt binaries) and it'll be much less

Is there any particular reason why you want to build Qt yourself? This is usually quite painful and requires a lot of extra stuff (see https://wiki.qt.io/Building\_Qt\_6\_from\_Git) . If you just want to avoid the (horrible) official installer and a Qt account, you can use aqtinstaller to fetch everything you need: https://github.com/miurahr/aqtinstall

Just recently, I had to recompile a (singleplayer) save game editor. So basically a GUI that does some clever hex editing.

It was written in C++ using Qt.

Have you ever tried compiling a Qt program on Windows? It involves signing up for an official Qt developer account to even install qmake.

To the point I had to use an unofficial Qt installer CLI app (aqtinstall) [0] to even install the toolchain to build this little shitty app... which still relied on having several Qt .dll files in the same directory as the .exe to work.

Have you clicked on [0] yet? Well, then guess what programming language aqtinstall uses.

Its deprecated in favor of Duende Identityserver which introduced a license model.

Tokens usually have a lifetime and they are separate from the user's authentication principals like username and password. Unless you are rolling your own form of token provider (not something that would be recommended) the token creation is handled for you. Take a look at https://identityserver4.readthedocs.io/en/latest/ or if your organization makes under 1M in income a year the free version of what Identity Server progressed into https://duendesoftware.com/products/identityserver

I think Duende (Identity Server) handled the situation pretty well.

> Standard License Pricing

Thanks for your message. No, the idea was not to re-implement OAuth nor OpenID stuff. What I had in mind for the authentication thingy was something like this: https://laravel.com/docs/9.x/sanctum. If we want to go the OAuth/OpenID way, in .NET we have this one: https://github.com/DuendeSoftware/IdentityServer.

> As you said, there are plenty of local options that you only need to run.

I think managed databases are a good analogy here. While I might run my own PostgreSQL/MariaDB instance, many out there won't be overjoyed at the idea of actually needing to run and manage the damned thing, as well as set up some kind of alerting and handling the need to eventually scale it up.

> It also has the largest risk of compromise and data leaking from any service you may use...

PII is definitely a big concern, even if something like password hashes aren't too useful on their own (provided that they're salted), though in cases like that it might actually make a lot of sense to utilize a widely used and tested solution that's specialized for this particular use case.

In many cases, thousands of people across the globe will be able to develop something and squash any bugs in it better than you might be able to do individually or with your own team, though there might be a few exceptions out there. Auth is probably not one of the cases where you want to write code without a lot of eyes on it.

> ...the largest amount of potential lock-in...

This is debatable: standards like OAuth2 and OIDC technically make many of the solutions and libraries way more pluggable and make it easier to choose between various implementations, depending on your needs.

Of course, something like Keycloak also has its own API (as do many of the cloud offerings) so if you build too much automation around a particular implementation, then that advantage partially goes out the window.

> ...and the least need for integration.

I'm not sure about this, it probably depends on your architecture. If you have a monolithic web app, then you probably don't need a separate turnkey/SaaS solution, whereas if you have an ever growing number of services, whilst you want to manage authentication and accounts against all of them centrally, then something like Keycloak (or one of the cloud alternatives) become way more lucrative.

That said, I'd still opt for self-hostable options whenever possible, albeit I also don't trust cloud based password managers and such, preferring something like KeePass instead. I've probably just come to a different conclusion in regards to usability/responsibility/features/security than some other people.

Sadly, there aren't that many good options out there at the moment, apart from Keycloak. For example, IdentityServer is promising, but went in a commercial direction: https://duendesoftware.com/products/identityserver#pricing

He's referring to IdentityServer 3/4, which was open sourced, and was not owned by Microsoft. That 3rd party is commercializing their work (and to be fair, it's a lot of work) as https://duendesoftware.com/products/identityserver , and has a different commercial licensing model.

https://github.com/DuendeSoftware/IdentityServer/blob/main/L... does not seem to square with any definition of "open source" I'm familiar with, and that goes double for having an in-repo file that just says "read this unversioned pdf on some other site"

I would not recommend it. There is a server named Duende identity server which you can host locally.
