My boss insists that we shouldn’t lock or password-protect a particular system because, in her words, remembering or write down a password is hard and email as a concept is confusing. I tried to explain if people who don't know what left versus right-clicking do have full admin access, it’s only a matter of time before something goes terriblely wrong. She listened but ultimately decided to keep everything open, confident that everyone would use it responsibly.
Unfortunately, that’s not what happened, it never has been and never will be. The problems started, just as I feared, and now I’m stuck cleaning up the chaos, one issue at a time. I do have a backup and automation snapshots, but things got so tangled up that it will still be a hassle.
I tried soft lock so everyone could only access the section relevant to them. The reaction was immediate—they were confused and stressed, saying they’d be unable to do anything if it stayed that way. They didn’t get the idea that keeping them from touching certain things (that they shouldn't be touching in the first place) wasn’t the same as blocking their whole work. But since they’re all my superiors, I had no choice but to remove the restrictions and leave the system wide open again.

Nothing serious came out, just really annoying because something like this happens all the time.
