Windows 10: My welcome page is now showing two accounts

My "welcome page" when i first turn on the laptop shows my name Anaya P, and says "The username or password is incorrect. Try again." When I hit "ok" it shows two accounts, with the same name. Apparently they have different passwords. To my knowledge, I never set up a second account. When I look at settings/accounts it doesn't show two accounts, just one. How do I get rid of the second one on the welcome page/starting page - whatever it's called - AND how to stop requiring password signin altogether? This is my laptop, I live alone, and I never take it anywhere, so there is no need for a pas
