I had to reset my computer, and all of my saved passwords were deleted. No problem, I remembered most of them, and also had them written down. So I go to this site, and the drop down comes in the upper right, something about password, and I look at it, and the password disappears in a half second.
What was that? I didn't know. Probably nothing.
The next time I come here, my password doesn't work. Why? Because that thing that dropped down was the Microsoft Strong Password Generator. It doesn't generate PassWORDS. It generates PassGIBBERISH like "QrDXV737Lgh3$g&cs@jk." So my new password it gave me for here was now like that, and I didn't even know it.
It seems that a reset causes the SPG to default to making a mess of user's passwords. I bet many people are now locked out of many of their favorite sites by it having changed their password without their permission. I don't need a strong password, I need a password that I can remember. Generally, I will think of a phrase in 日本語 (Japanese) and then spell it in Romaji (phonetic English characters.)
It took me two hours to analyze the problem and solve it by turning off the SPG. A big part of the problem was that Microsoft Support is useless. Nothing about it on YouTube. Finally the big breakthrough came when I was able to follow the Settings and More> prompt by finding it off the bottom of the screen, needing to be scrolled down to.
