Please assist me in trying to link several Xfinity accounts so I don't have to remember four different sign ins and passwords. I have tried to do this unsuccessfully for the past week.
There's an article we have that describes the steps, but it needs to get updated a bit for clarity.
In a nutshell, you should choose one to be your source sign-in credentials, then you need to sign into the other accounts and invite a new user, designate them as a "manager", and invite them using the mobile phone number and email tied to your source sign in credentials.
Eg. firstname.lastname@example.org is my verified email on my source account.
Then I have the username jonathanComcast123 for another account, jonathanComcast124 for another account, and jonathanComcast125 for yet another account.
I'd sign into each of those, and I'd go under the Users tab and click "Add New User"
Then rinse and repeat for each account.
Then sign back into your source account, and you should see them all linked under https://customer.xfinity.com/#/settings/account/linked-accounts
