If you log into your Samsung account on the desk top> scroll over and click "devices"> then click "Find My mobile" there will be an option to unlock your device so you will be able to undo that pin you set by mistake.
If you know the PIN or password you can go into the Settings under Lock Screen and change it to Swipe only.
