I do not have the computer set up to need a password. The thing about the prompt is that it does not do it every time. And it does say that the others logged will lose data.
I learned a long time ago that if I was posting something here, and I back tracked to check something, then I would not be able to get back here and then lose everything in the post and would have to start over. Now when I am typing a post like this, I will minimize it and then log on to the internet again. I would copy from that link, then maximize this link again and then paste. I thought that might be what was causing the prompt, but when I experimented with it, I did not get the prompt. I even logged on to the 'net 3 times and then shut it down with no prompt.
