How do I recover my backup password for Note 4?

[AC Question]

I do not know what my backup password is or how to retrieve it. I have tried android device manager and when I try lock screen, it says there is already one. Samsung tells me to call sprint and sprint tells me to call Samsung.

You can't - if you could, anyone could, right? Then your phone wouldn't really be password protected, the password would just be a minor annoyance.
