I changed my Windows signin to a 4 digit login, which works fine....

today i I noticed there were two signin options for my user account , exactly the same name, plus one other I have for a family member.
i chose one of ' my' accounts and it asked for a password, I tried the one I previously I used which was rejected....I then chose to reset my password...eneyer ed my four digit pin, then my Windows email password, then got a phone call with a verification number to enter, then was presented with a screen to create a new password, only problem was it also asked for my old one, which I didn't know, which was the whole reason I went through the procedure....

i then hen chose the ' other' signin and was able to enter my four digit number.....

so so all is ' sort of' OK but can't see this 2nd account of mine in control panel users.....so want to just have one the one requiring the four digit number...

any help please

thanks
