I cannot set up my Comcast email account on my iPhone. It keeps telling me my password is missing but it is not missing

Hello cookess,

If you're having an issue adding your email account on your device, please be sure to review all of the information outlined in the link you came from, to ensure the correct process is being used to add the account, so we can make sure that's not part of the issue: Add an email account to your iPhone, iPad, or iPod touch

Enter account settings manually 

If Mail can't find your email settings, then you need to enter them manually. Tap Next, then follow these steps:

1. Choose IMAP or POP for your new account. If you aren’t sure which one to choose, contact your email provider.

2. Enter the information for Incoming Mail Server and Outgoing Mail Server. Then tap Next. If you don't have this information, try to look it up.

3. If your email settings are correct, tap Save to finish. If the email settings are incorrect, you'll be asked to edit them. 

If you still can't set up your email account or save your email settings, contact your email provider.

If the above process has been completed, and you continue to experience an issue, please contact Apple Support for additional assistance. You might be able to reach them here: Contact Apple Support

Thanks!
