Windows 10: Apparently I don't know my passwords, how can I circle this?

I was on a BSOD loop for hours until the PC could at last move past it and somehow update. Then it came to check into it, says PIN isn't working anymore for some reason. I then try logging in with the same password I had for years and says it's wrong. I reset it on my phone and try again, same problem.I contacted help center to try something new and they guided me through some command prompt tricks but no use either.What exactly is going on and how can I possibly circumvent this issue?

Don´t remember password

Is there anybody here who knows if there is a way to open the microSD card when you have forgotten the password?



Both my daughters have forgotten their passwords and can´t use their cards after their phones have been to service. Thankful for any help.
