Can't log into Spectrum's outside WiFi? - Time Warner Internet

This question is about "Can't log into Spectrum's outside WiFi?", with Time Warner Cable internet and apps. Yesterday while waiting for my dentist appointment, I noticed a Spectrum's WiFi near by. So I decided to try it, but couldn't log in with my account as shown in my uploaded iPhone 4S' screen capture/shot. Shouldn't the old TWC->Spectrum account still work? I remember TWC's wifi worked many months ago (last year?) without having to log in too. Did Charter change that?
