3rd Party Emails not working after requested password update

Since updating my password per xfinity's request I can no longer access my emails on my iPad, iPhone, or Desktop.  To reduce the response time to the real issue I have done the following:

1. I did reset my passwords on all my devices.
2. I did check that third party access was checked.
3. I even unchecked it logged off and then checked the third party access back on.
4. I removed my account from various apps and restored them.

I am able to access my email via a web browser but this is incredibly inconvenient when I rely on being able to access my email quickly, especially from my phone. 

I see where others have had this problem previously.  Why does this seem to be an ongoing issue?  Any suggestions on how to get this resolved?
