Change your username online through your account settings

Find the option labeled Username, Login ID, or Sign-In Name. Click on it. Xfinity will ask you to confirm your identity by sending a code to your email address or phone number on file. Enter that code when prompted. Then type your new username into the field provided. Xfinity will tell you when ready if the username is already taken or does not meet the character requirements. Once you see a confirmation message, your new username is active.

The change takes effect right away. You do not need to wait or restart anything. The next time you log out and log back in, use your new username instead of the old one.

What to do if you cannot remember your current username

If you are locked out or straightforward cannot recall your username, you can recover it without changing it first. Go to xfinity.com and look for a "Forgot username?" or "Need help signing in?" link on the login page. Click it. Xfinity will ask you to enter either your account number (found on your bill) or the phone number associated with your account.

After you provide that information, Xfinity will display your current username or send it to your email. Once you have it, you can log in normally, then follow the steps above to change it if you wish.

Change your username by phone if you cannot do it online

If you do not have access to your email or phone number on file, or if the online method is not working, call Xfinity customer service at 1-800-934-6489. Have your account number and a form of ID ready. A representative will verify your identity, confirm your new username meets Xfinity's rules, and make the change for you over the phone.

Phone support is available 24 hours a day. Wait times vary depending on call volume, but you can check current wait times on the Xfinity website before you call. Some Xfinity customers also have access to chat support through their account, which may be faster during peak hours.

Why your new username might be rejected

Xfinity rejects a new username for a few specific reasons. The most common is that someone else already has it. Usernames must be unique across all Xfinity customers. If you see a message saying the username is taken, try adding a number to the end or using a variation.

Your username also cannot contain spaces, punctuation, or special characters. Xfinity only allows letters (a–z, A–Z) and numbers (0–9). If you try to use something like "john.smith" or "john-smith", the system will reject it. Use "johnsmith" or "john123" instead. Usernames shorter than 6 characters or longer than 32 characters will also be rejected.

How long the change takes to show up everywhere

Your new username is active in your Xfinity account when ready after you confirm it. You can use it to log into xfinity.com and the Xfinity My Account app right away. However, if you use Xfinity email or have linked your Xfinity account to other services, those connections may take a few hours to update. If you see an error when trying to log in somewhere else, wait a few hours and try again.

Xfinity recommends not changing your username more than once in a 24-hour period, as the system sometimes needs time to sync the change across all its servers. If you change it twice in quick succession, you may run into temporary login problems.
