How do I turn off the security feature on Galaxy S6?

[AC Question]

I currently have a password on my phone through the settings on the phone. I downloaded a security app that does the password through there instead of the phone setting, but I am not able to choose none as the option for security through the phone.

In that case uninstall the app you downloaded

You may have an app that is requiring you to keep the samsung passcode valid.
Samsung pay comes to mind.
