Unable  to receive my email. It keeps asking for a password for imap!  What is this? Please help!

If you are using Comcast's servers (connect.xfinity.com, mail.comcast.net, imap.comcast.net, and smtp.comcast.net), the email (IMAP) password is the same as the password you use to log in to a Comcast/Xfinity web page or app. There is no separate "IMAP password". If you need to reset it, see https://www.xfinity.com/support/articles/changing-or-resetting-your-password. If you change it you'll also have to update it on any devices, apps, and programs (email, Xfinity app. etc.) that use it.
