Win8.1 log-in/sign-in screen

Says the username or pw is incorrect.
I downloaded a scanner app from the store and had to change my PW to get into the store and now idk how to save it to auto-log-in to my laptop. (Surface Pro 3)

Sounds like a password manager, but it is unclear what you are using and what you need.
Which 'store'?
Which OS? Windows 8.1 (edition?)
What is model of laptop?
What scanner app?
Is this a password manager separate or included in OS?

Log-in/Sign-in screen for windows 8.1 on my Surface Pro 3
Start the SP3 and it pops up telling me the user/pass is incorrect before logging into windows
Windows store, for SP3 apps.
Just a basic HP OfficeJet scanning app.
