You can change your Xfinity username through your online account or by calling Xfinity customer service

Your Xfinity username is what you use to log into your account at xfinity.com or the Xfinity My Account app. If you want a different one — because you've changed your name, prefer something more private, or straightforward want something easier to remember — Xfinity lets you change it yourself without waiting on hold. The process takes about five minutes if you do it online, or longer if you call.

The online method is faster and available 24 hours. The phone method works if you're locked out of your account or prefer to speak with someone. Both routes end with the same result: a new username that takes effect when ready.

Key Takeaways

  • You can change your username online at xfinity.com by signing in, going to Account Settings, and choosing a new one that hasn't been taken.
  • Your new username must be between 6 and 32 characters, can include letters and numbers, and cannot contain spaces or special characters.
  • If you cannot sign in to your account, call Xfinity at 1-800-934-6489 and a representative can change it for you over the phone.
  • Your new username takes effect right away, but you should write it down because you'll need it the next time you log in.

Change your username online through your Xfinity account

Go to xfinity.com and sign in with your current username and password. Once you're logged in, look for "Account" or "Account Settings" — this is usually in the top right corner or in a menu labeled with your name or profile icon. Click it.

Find the section labeled "Username" or "Login Information." You should see your current username displayed. Next to it, there will be a button or link that says "Change" or "Edit." Click that button. Xfinity will ask you to confirm your password again for security.

Type your new username into the field. It must be between 6 and 32 characters long. You can use letters (uppercase and lowercase both work) and numbers, but no spaces, hyphens, underscores, or special characters like @ or #. As you type, Xfinity will tell you whether that username is already taken. If it is, try a different one. Once you find one that's available, click "Save" or "Confirm." Your new username is active when ready.

Change your username by phone if you can't access your account

If you've forgotten your password or can't sign in for another reason, call Xfinity customer service at 1-800-934-6489. Have your account number ready — you can find it on your Xfinity bill or in any email from Xfinity. You may also need to provide your service address or the phone number associated with your account so the representative can pull up your account.

Tell the representative you want to change your username. They will ask you to verify some information about your account, then they can change it for you. Write down the new username they give you or confirm it before you hang up, because you'll need it to log in next time.

What happens to your old username

Once you change your username, your old one becomes available for someone else to use. Xfinity does not hold it for you. If you change your mind within a few minutes, call back when ready and ask if they can change it back — but there's no may provide they will do this, so choose carefully before you confirm.

Any saved passwords or autofill settings on your devices will no longer work with your old username. You'll need to update them with your new username. If you use your Xfinity login to sign into other services (some apps or websites let you "sign in with Xfinity"), those will also stop working until you update them with your new username.

Rules for choosing a new username

Your username must be unique — no one else on Xfinity can have the same one. It must be between 6 and 32 characters. Letters and numbers are allowed, but spaces, hyphens, underscores, and symbols are not. Xfinity will reject usernames that contain profanity or that look like email addresses (ones with an @ symbol).

Your username is not the same as your email address. Even if your email is something like jane.smith@gmail.com, your Xfinity username could be janesmith42 or any other combination that follows the rules above. If you want to change the email address associated with your account instead, that's a separate process done in the same Account Settings area.

Troubleshooting: username won't change

If you see an error message saying the username is unavailable, it means someone else has already taken it. Try a different combination. If you keep getting an error even with a username you've never tried before, wait a few minutes and try again — sometimes Xfinity's system needs a moment to catch up.

If you're signed in but the "Change" button doesn't appear next to your username, try refreshing the page or clearing your browser's cache. If that doesn't work, try a different browser or device. If you still can't find the option, call 1-800-934-6489 and ask a representative to change it for you.

Frequently Asked Questions

Can I change my username more than once?

Yes. Xfinity does not limit how many times you can change your username. You can change it as often as you want, though each change takes effect when ready, so plan ahead if you're changing it for security reasons.

Will changing my username affect my bill or service?

No. Your username is only for logging into your account online or in the app. It has nothing to do with your service, your bill, or your account number. Changing it will not interrupt your internet, TV, or phone service.

What if I forget my new username?

Go to xfinity.com and click "Forgot username?" on the login page. Xfinity will ask for your account number or the email address on file, then send you a link to reset it. You can also call 1-800-934-6489 and a representative can tell you what your current username is.

Can I use my email address as my username?

No. Xfinity does not allow usernames that contain the @ symbol. Your username and your email address are separate. Your email is used for password resets and account notifications, while your username is what you type to log in.

Does my family member need their own username?

If you share an Xfinity account, you all use the same username to log in. If you want separate logins, you would need separate accounts. Contact Xfinity at 1-800-934-6489 to discuss setting up additional accounts on your service.
