You know, I thought about this the other day... nothing personal, it just happened to pop in my head.
Google allows the use of the same login everywhere you go. Which I don't consider safe to start with. (Though they certainly don't have a monopoly on this.) But worse, for work we use the google cloud. Whenever I am logged in there and I go anywhere else of google's, it automatically takes my work login with it. My work login not only requires my full real name, but it also includes the domain of my work. So I go somewhere else and I'm logged in with my real name and the place where I work, and am not always thinking about it. I'm not only an extremely private person, I'm even more private on the internet and never use my real name, and also just don't think where I work is anyone's business and should not be associated with social things that I am doing.
This happened about two days ago, that I was doing some personal stuff, glanced up and noticed my work login up in the corner and had to log out of my account real quick. Which is what made me think of this...
