Specifics: I use a Dell core i3 laptop (10 months old). The operating system is windows 8.1. There are two users: myself being primary (admin), and my daughter being secondary. I switch the laptop on, then enter the password, what the laptop refuses to accept. Though, my daughter (as secondary user is able to log into her account). 8 hours ago everything worked fine.
If it says the password is incorrect then it is in fact incorrect. If your daughters account is an admin then you can simply reset your main account password.

does your password have a @ or a $ in it?
if so then you may have set your keyboard to a different layout and the work around would be to plug in a usb keyboard to sign in with
