Unable to send through smtp.comcast.net due to Comcast.net email no longer working

I have a few scripts that need to send out emails and historically I used smtp.comcast.net:25.  I don't recall ever needing to authenticate to it, but now I do.  I have a @comcast.net account (not my Business portal account) that I used "xfinitywifi" hotspots for.  When I try to log in, it tells me "You'll need to connect to your home WiFi, then navigate to xfinity.com/password to complete a password reset. If you still need help, give us a call at 833-520-0211".  I am on my Comcast internet..  I contacted that phone number and was unable to get support.

So I guess I have two questions, how do I send SMTP emails from comcast business, and two, what happened to my @comcast.net account?
