A common cause of this error is using an incorrect username when attempting to log into the app. We also notice this error when a customer has signed up for Xfinity Home security with a non @comcast.net username.
I have private messaged you.
Hi denrue & mcroxton3 -
We experienced an issue beginning yesterday that led to increased 43401 errors for users. We are actively working on a resolution & I will provide updates on the issue as they are available.
I have added your accounts to the list of forums users that are posting & will continue to track this for you both.

Currently we are experiencing a larger issue that is causing 43401 errors for users even when they are inputting the correct log in information. We are actively working on a resolution & will provide updates on the issue as they are available.

Hi lindmahill -
I pulled up your account info & see that you are attempting to log in with multiple @comcast.net email addresses. At this time, we only support signing in with the username/email that was provisioned when you signed up for service. I have private messaged you with the primary username/email address to confirm you have the correct address to use going forward.
Please let me know if you have any further issues.
At this time, we only support signing in with the username/email that was provisioned when your Xfinity Home service was activated. During the Xfinity Home security activation (Tech install), the email address that is used to log in becomes the primary email address associated with the account.
