New account with yahoo

They sent me a email with a link twice.  Click on it and it just logs me in . Never see any terms

Thank you for choosing Xfinity !

Starting now, customers that are yet to update their account will no longer be able to log in via their email addresses due to recent security upgrades. unverified emails will be listed as dormant emails.

Thanks for sharing information about the email you received. That doesn't appear to be an official email from Xfinity. You can confirm this by checking the email address the message was sent from. As that looks to be a phishing attempt, I would advise that you not click on the link or provide any login information, and if you already have, you may want to reset your password.
