I sort of agree with you, but not in the way I think you meant it.

Vista’s problem was that it’s hardware requirements were too high for it’s time. Operating systems have very long project development lifecycle and at a point early on they did a forward looking estimate of where the PC market would be by the time Vista released, and they overshot. When it was almost ready to release it to the world Microsoft put out the initial minimum and recommended specs and PC sellers (Dell, HP, Gateway) lobbied them to lower the numbers; the cost of a PC that met the recommended specs was just too high for the existing PC market and it would kill their sales numbers if they started selling PCs that met those figures. Microsoft complied and lowered the specs, but didn’t actually change the operating system in any meaningful way - they just changed a few numbers on a piece of paper and added some configurations that let you disable some of the more hardware intensive bits. The result was that most Vista users were running it on hardware that wasn’t actually able to run it properly, which lead to horrible user experiences. Anyone that bought a high end PC or built one themselves and ran Vista on that, however, seemed quite happy with the operating system.

Why is Zoidberg alone on Xmas? What happened to Marianne?

That is the specific app the person I replied to was asking about, so yea. Would have been a little weird if I was talking about some other app.

Mostly. The 6 digit standard ones that you see almost everywhere are standard TOTP codes and most apps work for them. There are some proprietary things out there too but you typically see those with a matching app from the same company. Those are far less common though so for practical reasons you can assume they are all interchangeable.

Those values are computed separately what the app is really storing is just the input values which are then combines with the current time to create the 6 digit code. That means that keeping that input value (seed) safe is a big deal, and how and where that is done is one of the major differentiators between the various options.

Google Auth works just fine. The standard for app generated 2FA is, well, standard. They’re only listing a non-complete list of options for people that don’t know what an authenticator app is and need to get one for the first time.

Too many people were making poor choices. When there’s an incident of an account that should have been secured but wasn’t getting compromised, that’s bad for the platform, ecosystem, and community. This is just another level beyond not allowing you to set a password of “password”
