comcast password changes
I have both icloud and comcast email accounts on my iMac and iPad2.
I use my Apple ID as password for the iCloud mail accounts on the iMac, iPad, and iCloud Web accounts (Chrome).
I would like to update the password for my Comcast account. Must I change the individual passwords on the iMac Mail, iPad, and the Comcast/Xfinity Web accounts, or can I update just one? Or can they have different passwords?
