Windows 10: Safe mode is saying incorrect password even after I changed it

I tried turning in my pc and it said my pin was unavailable so I decided to go into safe mode and uninstall my last update. When I got into the menu I typed in my Microsoft password and it said it was wrong. I went on my phone and changed my password so I could u it all the update so I can actually use my Pc. But after I changed the password I went back on my Pc and it still said wrong password. I don’t know what to do and I can’t enter my pin to get into Windows. I’m stuck with a Pc that cannot work and I am very frustrated. If anyone knows how to make the password acceptable it would be amaz

Problems with password in Safe Mode

When I try to log on to my desktop computer in Safe Mode it tells me my current password is incorrect. If I log on to my laptop computer in Safe Mode my current password is accepted. My wife can log on to my desktop computer in Safe Mode using her current password without any problem. If I log on to my desktop computer in Safe Mode using my previous Microsoft password, however, that is accepted.

Can anyone suggest what might be the problem with my desktop Safe Mode log-on and how I can get it to accept my current password, please.

Thanks in anticipation.
