Can’t Update Apps without Entering Apple Account password

Whenever I try and update one of my apps it asks me to enter the password for a family members apple account that I do not know. I don’t remember ever linking my phone to theirs and this is the only spot in my phone where their account comes up, everything else is mine. But I do not have the password or anyway to get it from them so I am unable to update any apps. Does anyone know if it’s possible to remove any link to their account entirely without having access to the password?
