Xfinity 2-factor Authentication is DEAD!

I'm trying to update my billing method and from a browser when I:

1) Go to Billing and Pay from the main menu

2) Click Manage Payment Methods

3) Click Add Payment Method

4) Click New Credit/Debit Card

5) A Verify your identity web page is displayed

6) When I select Text Message to mobile phone or when I select email the code, the server returns with the Verify your Mobile Number or Verify your Email with the server message (in all red): "Failed to generate verification code" (without the quotes

There is NOTHING I can do at this point and if my payment was due, I would be considered late because the xfinity/comcast servers {Edited: Language]!

Why does this keep happening to Xfinity/Comcast? Do you not want our money?  Does management know how pathetic your IT group is if they can't get a simple server app to work to generate a code?

Come on guys!

@user_xaqlgu Thank you for letting us know. By any chance on your web browser did you try to clear your cache and cookies just to see if that made any difference? We appreciate you reaching out today with your concern.

Again, this has nothing to do with it.  The same error shown on three different computers (one Mac, two Linux) and on two devices (iPhone and iPad).  The cache has nothing to do with it (sorry, but I'm a retired Professor of computer science and I know a lot, with all humility, about this stuff)

The authentication server seems to be up now (8 hours later).  I was able to update my billing information.

Someone in IT needs to figure out why this keeps happening. I saw posts as old as three years ago complaining about this.  Isn't Comcast/XFinity a technology company?

user_xaqlgu There was a known issue reported after we spoke last. It is not an ongoing issue. There was a temporary issue with an update that our engineering team had to roll back and correct. Thank you for the update, and I am glad you were able to authenticate your account.

I did this, and NOTHING worked. I even used the app. I still get this error message. I don't know why my saved payment methods are no longer saved but now I can't pay my bill and can't log in due to the failed verification code generator to add a payment method back in.

Mouser12 thank you for using the Xfinity Community Forums page to reach out today. Just to confirm are you trying to update your billing information as well or just use the saved information? Are you receiving the same error code that the original posted indicated they saw on their end?

@XfinityMarcus​ I was trying to update billing information and got the exact same error as OP. It is fixed now though so not sure if it was fixed (I didn't do anything on my end, or if support texted me a code and it allowed me in) but I did not receive an error message this time when trying to log in and get a verification code texted to me.

Mouser12 thank you for that additional information, I do know that we replied to your direct message from earlier and tried sending over a code to complete verification on our end. That may have been what you received.
