Like many others I deleated all my TWC apps and wherever I go I get bothered by the screen "Incorrect Wi-Fi Password.... Enter the password for"TWCWiFi-Passpoint." Even if I try to connect by entering my password it fails. And If I do not want to connect and select "Cancel" the screen returnes constantly until I leave the area. While driving and using navigation this screen pops up. I have turened off "Ask to Join" in my WiFi settings, deleated TWC apps but all attempts failed to solve the problem.
I remembered some time ago being asked by one screen or another about using the TWC free Wifi HotSpots but could not remember if it was on the phone or on the computer. So here is what I hope is my fix for my iPhone 6s. This will hopefully prevent any auto login attempts by TWC WiFi, you will have to search for those connections.
go to:
SETTINGS
GENERAL
PROFILE (at the bottom below VPN)
TWCWiFi-Passpoint Profile (select this)
Delete Profile (yes, select delete the profile)
Hopefully this will solve the problem
