Which Xfinity ID do I use during the Yahoo switch over

@jl747 

Since I can use both comcast.net and gmail.com to log in to my Xfinity and Forum accounts.

When the time comes which Xfinity ID do I use during the Yahoo switch over?

Thanks

You will get the invite to your @comcast.net email account - so it would be whatever your email address is for @comcast.net.
