Computer asking for password on start up that isnt my normal password
I left my computer in the computer room and when I came back it had a screen that was black and a blue box in the middle (see image).
It asks the enter password but it is not the password I usually use to sign in with. From what research I have done it appears I have to put in some sort of admin password (not the admin account tried that) or a password that came with the computer.
I no longer have to box or instruction manual stupidly threw it out and I appear to be lack of a serial number on the bottom of my laptop.
I have tried calling asus support but cannot get through.
I do not want to do a hard reset as I have documents I need to get to.
Also this is the actual computer I have (running windows 10) as I could not find it in the options
