How do I find out who have email addresses on my account? Have had an account for a number of years and assigned family members email addresses back in the day. Comcast mistakingly terminated my account and had to restore it. They claimed that everything was restored but I ended up with a new account number.
Sign into your primary account, and at the top of the homepage click on "My Account". It will ask you to sign in again. On the landing page click on "Users" at the top of the page. There you should be able to see any secondary accounts you may have.
