Signing in to my lap top

Three people are authorized to sign into and use MY Lap Top. My wife rarely does, thus she can't remember password. I can use "account.live.com/password/reset with my Microsoft account and sent code number to her cell phone. Question will that code be for
her or for me. Understand that.....she's not trying to change email PW, proplem is that she does not know PW to log into the lap top and will need to use my Microsoft account to do so is that possible or is there another way.
