Using
macOS 10.13 High Sierra:
I would have sworn that for the last few years (not days or months, but years!) my log in screen had only one choice; my login name, picture and a single password entry field. OK, there was also a "Restart" and "Shutdown" button.
However, for the past 10+ days, I now see an "Other..." choice. I have tried every combination of Login Options available and cannot get rid of that extra choice in any satisfactory way.
I can get rid of all pictures and names by setting the Prefs to "Name and Password" regardless of the remaining options. However, that now requires two text fields, with the accompanying extra keystrokes.
By using the "List of users" method, I can have only the Password field show. But now, I have to press either the "left" or "up" arrow key to select which user I want (No one at our house is named "Other", so I always want me...
). That is only one extra keystroke, but it's just not what I've had to do until recently! Who changed that?
Please tell me that I am not losing my mind and that you have exactly the same display in High Sierra.
The only thing that seems related is the now
constant nagging from iCloud to set up two-factor authentication. That happened not long ago... It also seems to force System Prefs to always open with iCloud prefs.
