Im A Dummy

So the other night my laptop which is an HP touchscreen 15.6 in whatever I don't know the rest of the stuff some but the internet on it stops working It wouldn't connect to Wi-Fi I decide to do a factory reset I factory reset it and it boots back up and when it does it gives me a username and a password I can't remember what I used on their what username and password I've tried all the ones that I know are familiar with and none of those work so then I take my wife's laptop with yours is pretty old or 5 or 6 years old it's a Asus or something like that an arm start to work on hers next thing I noticed that the username switched over to what I'm assuming was on the HP and and now I'm locked out of both computers I just even if I have to factory reset on another the informations on there and it's important I I have all my important paperwork or documents on my 2TB passport

If you did a factory reset you shouldn't need a user name or password. A factory reset should be the same as the day you first started the computer.
