Fun fact: password controls like this have been obsolete since 2020. Standards that guide password management now focus on password length and external security features (like 2FA and robust password encryption for storage) rather than on individual characters in passwords.
Since 2017 at least; and IIRC years before that; that's just the earliest NIST publication on the subject I could find with a trivial Web search.
https://pages.nist.gov/800-63-3/sp800-63b.html
"Memorized secrets" means classic passwords, i.e. a one-factor authentication through a shared secret presumed to be known to only the right person.
I wouldn’t say obsolete because that implies it’s not really used anymore. Most websites and apps still use validation not too dissimilar from the OP, even if it goes against the latest best practices.
Yeah, the most recent one for me was creating a password at lemmy.world
I'm not sure where you heard someone use the word "obsolete" that way, but I assure you that there are thousands if not millions of examples of obsolete technologies in constant and everyday use.

Yeah i agree. The best example of this is Linux. To anyone who disagrees, why does a modern operating system require you to use a terminal, or edit config files instead of changing settings in a gui?
Its THE example of ancient software being pushed on to niave techies that would rather have an insecure open source project than a safe, walled garden like Microsoft Windows 11.
Although Windows 11 does have its problems. The chief of which is bogging down the streamlined simplicity with things a normal user wont need like a package manager.
Ouch... so, you might want to learn more about technology before commenting in a Technology community...
Because a terminal is one of the most powerful modes of interaction ever invented. It can serve as a relatively low-tech UI, but it is also simple enough to be used as a machine interface. It is lightweight, works even when other protocols and interfaces are thwarted by infrastructure issues, because it is simple text, but also meant to be read by a human, it can make for a great interface for logging, you don't have to guess at which obscure standard (if any) to use to talk to it, compliance with relevant standards is baked into nearly every language ever written, etc.
Try building a system like Kubernetes on graphical UIs... I dare you.
What industry are you working in?! AWS is nearly all Linux. Google Cloud is nearly all Linux. Android is Linux. Hell, even Microsoft finally relented and is now strongly supporting their Windows Subsystem for Linux (WSL) because it's necessary for supporting modern cloud applications.
Okay, this has to be a troll... right? This is a troll? Please tell me you can't be serious.
I know it can be hard to have your ideas quedtioned, but at least try to be civil. I never questioned your intentions, yet youre acting like im crazy. A walled garden is obviously more secure than an open source project because nobody can even see the code to find vulnerabilities in it. There is a reason why Android is moving further and further away from open sores code.
I understand that you like horses. You ride one every day, and you might have evwn named your horse. The fact is that its time to buy a car. Notice i said buy. Quality software costs money, and always will. Its time to move into the future with the rest of us.
Yes i agree. Throwing rocks is also simpler than firing a gun, yet modern militaries arent training slingers anymore. Ive developed games using Windows exclusivley (for a lot of money i asure you) and ive never once had to use a terminal ever. I literally just have to email my source code to my boss, and he compiles it. I have no need to know how, because its not my problem. Theres no need to use a terminal when i have Visual Studio and Outlook. If you want to be a cool hackerman you can, but id rather use something thats intuitive and works.
I think anyone who uses Linux is stuck in the past. Communism doesnt work either, bucko.
I think that's all you. I have never suggested that you are crazy. I suggested that calling Microsoft software "safe" as opposed to Linux which is, "insecure," sounds like trolling. But that's because it sounds like trolling. No crazy stated or implied.
You should learn more about the world of software. Seriously. Security experts have been reasonably unanimous in their support of the "Many Eyes Make All Bugs Shallow" approach to software security for decades, even while they have criticized it as a mantra that ignores the flaws in a presumption of open source software security.
But just to put it in a simple logically sealed box: Microsoft's source code has been leaked several times, and of course, bad actors probably have gained access to it throughout the years without such public knowledge. This means that the fundamental difference between Microsoft's proprietary codebase and open source codebases is not, cannot be the availability of source code. Rather, it is the ability for independent groups to review the code on an ongoing basis.
When the only difference is independent review, the only possible result is higher security.
None of this constitutes a logical refutation to the examples I provided, which are critical components of modern software development and deployment.

For starters, this is unfounded cargo culting. There is no evidence for this at all. I can point to dozens of very expensive piles of crufty old software that no one should ever go near, and also to some free software that is literally foundational to the modern software world.
Money has nothing to do with the quality of software, but you're also mistaken if you think open source software is free. You can pay IBM millions of dollars for a suite of enterprise-ready open source software. Most of the cost in such software is rarely the software itself. It's services, support, training and customization.
But they are succeeding wildly by using largely open source software running on open hardware for drones, networking, battlefield analysis, logistics, etc.
For today's 10,000 who have never seen it, https://xkcd.com/936/ succinctly explains why the whole mixed character types thing isn't favoured.
I'm still waiting on an XKCD that references #936 with the fact that we soon as we have reliable, functional quantum computing, all of the passwords from before that point in time will be completely and utterly broken. That the only way to make a password that a quantum computer would have a tough time breaking is if it was made by another quantum computer. Unless of course the comic has already been made and I just missed it, which is a complete possibility because this year for me has been utterly crap.
Some of them are broken by quantum computers, but not all of them. For example, SHA256. You can use Grover's algorithm to take sqrt(n) steps to check n possible passwords, which on the one hand means it can be billions of times faster, but on the other hand, you just need to double the length of the password to get the same security vs quantum computers. Also, this is the first I've heard of a hash that uses a quantum computer. Do you have a source? Hashes need to be deterministic, and quantum computers aren't, so that doesn't seem like it would work very well.
Maybe you're getting mixed up with using quantum encryption to get around quantum computers breaking common encryption algorithms?
Except you can run a dictionary attack on that and suddenly it's only 4 variables that are cracked way faster than the first password.

Yeah! And nowadays the industry is pushing towards password less authentication. Github just started rolling it out to beta users
People should be made aware of all the tools available to properly manage tons of passwords. Not even going too deep into "passkey" stuff or any modern shenanigans, but a password manager used to generate random passwords for each separate sites is such a simple step.
