Any app to lock iPhon?

[Mr_AliMaMa]

I need to disable my iPhones built in pass code security feature to get some iPhone accessory to work so my iPhone has no security so is there some type of app jb or not that can replace the built in security code

I'd ont see the different having a 3rd party lock apps. It still lock and your device still not accessible.
