Comcast.net Email Login. Login to your Xfinity Email or Comcast.net Email account via your PC, mobile phone or the Comcast app. Everything you need to know about the Comcast Email and Xfinity Email services. About Comcast. The Comcast.net email service is a webmail service provided by the Comcast Corporation; a telecommunications company, which is currently the largest cable internet service provider in the United States. The company itself was founded in 1968, began offering internet services in 1996 and is based in Philadelphia, Pennsylvania. In 2010, Comcast merged with NBC and began to re-brand its cable television, internet and telephone services, using the brand name Xfinity. This means that Comcast email is now technically known as Xfinity Mail. Nevertheless, under the terms of the re-branding process, customers are still able to access their old Comcast.net webmail. Xfinity Comcast Email Login. How to Log In to Your Comcast Email/Webmail Account. As previously stated, Comcast email has now been re-branded to Xfinity Mail, but existing customers are still able to access their original Comcast.net email accounts through this service. This is done through an offering known as 'My Xfinity' (http://my.xfinity.com), which is where the old Comcast.net web address now re-directs to. From there, click on the link in the top right hand corner, which is labelled 'Sign In'. On the right, you will see a login box. Enter your full Comcast email address, or your mobile phone number if it is linked to your account, then enter your password. You will also need to enter a security code, which will be displayed on screen. Then, simply click the 'Sign In' button underneath the form to gain access to your Comcast account. You can also go directly to the Comcast login page here, or navigate to https://webmail.comcast.com/, as an alternative. Please pay attention when trying to log in. Fake login pages are constantly popping up on the internet, with the aim of extracting your email credentials. The official Comcast Email login page should look like the screenshot above, and the correct url begins with https://login.comcast.net/login. Alternatively, you can login from https://webmail.comcast.com/. Common Comcast Login Problems. Occasionally, users may encounter login problems when trying to access their Comcast email account, although these usually have a simple solution. The most common explanation is that you have entered the wrong credentials, so please double check for typing errors in either your email address or password. Your mobile number will only work, if it is already linked to your account. It is important to remember that passwords on the site are case sensitive, so they must be entered exactly as they were during the sign up process. Take care when entering the password to avoid any misplaced upper case letters, and make sure that the CAPS LOCK function on your computer keyboard is turned off. You will usually be asked to enter a security code to prove you are a genuine user, rather than a bot. This code needs to be entered exactly as it appears. If you continue to see an error message, click the link marked 'Get a New Challenge' and try again when the next security code is displayed. At times, the My Xfinity service may undergo scheduled maintenance work, which can make Comcast email login difficult, or even impossible. Unfortunately, the only real solution to this is to try again later. If you continue to experience problems, you should try clearing your web browser's history, cookies and cache. You may also need to close the browser and restart it before you try again. If this still does not solve the problem, try signing in with a different web browser, or by using a different device altogether. I have forgotten my Comcast Email Password and User Id. Underneath the main Comcast email login form, you will see a piece of text saying 'Forgot Username or Password?' If you have forgotten your username, click on the word 'Username' here and you will be able to recover it. To do so, you will need to provide either your mobile phone number, your social security number, or your Xfinity account number in order to identify yourself. Follow the on-screen instructions and your username will be displayed. On the other hand, if you have forgotten your password, you should click on the word 'Password' instead. Here, you will need to provide your username and your recovery email address, which should be different from your main Comcast.net account. A password reset email will then be sent to this email address. Go to your inbox, open up the email and click on the link contained within. You will then be able to choose a new password and regain access to your account. If you cannot see the password reset email in your inbox, you may need to check your spam or junk mail folders instead, as it can sometimes be diverted there.
