Can't log into my email account - Time Warner Internet

This question is about "Can't log into my email account", with Time Warner Cable internet and apps. I decided to check my spectrum emails after not checking for a while (I use yahoo for my reg/daily emails). I get to the log in screen and enter my info and they say that this info is not valid with my account. Can someone please help me with this? Please and thank you.
