Login Issues

Like many here, I have had my comcast email since the 1990's.  Sometimes lately I have been able to get into my mail if I do it on a daily basis. 

But I can't always do that so when I skip a few days I have to fight to get back in.  It takes at least 3-4 times when they send a code to my phone. but tonight it did not work after 4 times.  It is very discouraging to try and get to my email.  And one problem I have is that I don't have the skills to be able to fix my email problems without help.  SCamp
