But why actively harmful?
You're conditioning people to treat a "password" not like a secret. If you missed the sign at the entrance, you'll ask the next person for the wifi password. And, of course, they'll usually give it to you.
That's obviously not how you should treat passwords.
We call a thing a "password" if it serves a security purpose, locks access to something that's for you, not for random other people. We probably shouldn't call things "passwords" that aren't like that.
What security goal does that password serve? I'd say, there's no reasonable "threat" you're defending against.
The password is freely shared.
Yeah, you're "protecting" your Wifi from being used by a random stranger sitting somewhere close enough to use it, but not a guest of your facility/event/... - but is that really something it's worth to protect against?
Not sure if this is a hot take, but: I believe most WiFi passwords serve no meaningful purpose and are actively harmful to security.
You all know how this works. You're in a hotel, at a conference, in a restaurant, etc., you want to connect to the wifi. There's probably a sign somewhere with the password.
First of all, it's annoying that you have to figure out where to find it, ask around if anyone knows it.

Europe's🇪🇺 failure to scale Green Methanol production leads to a compounding failure to attract one of the most promising projects for a fossil-free future chemical industry🌱⚗️🏭
It all feels like what played out in the Solar☀️ industry. China invests early and big. More in my latest newsletter.
Was this real? Announcing things is cheap; building things matters🏗️
In 2025, it became clear that it is real.
4 industrial-scale Green Methanol plants are operational in China. In Europe? 1
In 2024, A.P. Møller Holding (owners of Maersk🚢) created the startup VioNeo, with plans for a fossil-free plastics plant in Antwerp🇧🇪. In 2026, they changed plans & want to build "in China near green methanol supply"
China's Green Methanol Industry is racing ahead 🇨🇳🌱⚗️🏎️
Many expect that Green Methanol is the future clean shipping fuel🚢⛽, as well as a promising feedstock for sustainable aviation fuels✈️ & fossil-free plastics🧴
In 2023, something happened in China🇨🇳.
Suddenly, announcements for Green Methanol production plants started appearing. They had one thing in common: they were huge💪. 500,000 tons here, a million tons there🏭🏭🏭

🧵
Methanol made from sustainable feedstocks is a key technology for climate-neutral shipping, aviation, and fossil-free chemicals. Chinese companies are already building industrial production facilities and surrounding infrastructure, while the rest of the world is falling behind.
The production of some nitrogen-based chemicals can cause substantial nitrous oxide emissions (N₂O), a potent greenhouse gas. Technology to stop these emissions is cheap and readily available, but it is not always applied.
And here's the good news: N2O is composed of Nitrogen and Oxygen💨, so one can turn it into Nitrogen and Oxygen. And that's really cheap💶 compared to almost anything else you could do to reduce emissions.
After having covered this already twice in my newsletter📰, I made a short video🎥 about it:
