Change your username and password through the Xfinity website or app

You can change both your Xfinity username and password yourself without calling customer service. The fastest way is through your Xfinity account online — the process takes about five minutes and the changes take effect when ready. You can also make these changes in the Xfinity mobile app if you prefer to do it on your phone.

Your username is what you use to log in to your Xfinity account. Your password is separate from your WiFi password — changing your account password does not change the password people use to connect to your home WiFi network. If you need to change your WiFi password instead, that is a different process.

Key Takeaways

  • Log into your Xfinity account at xfinity.com, go to Account Settings, and select Change Username or Change Password to make either change yourself.
  • Your new username must be between 6 and 32 characters and cannot contain spaces or special characters like @, #, or &.
  • Your new password must be at least 8 characters long and should include uppercase letters, lowercase letters, numbers, and symbols for stronger security.
  • Changes take effect when ready, so you will need to use your new username or password the next time you log in.
  • If you forget your new password after changing it, use the "Forgot username or password?" link on the Xfinity login page to reset it.

Step-by-step: changing your username on xfinity.com

Go to xfinity.com and log in with your current username and password. Once you are logged in, look for your account menu — this is usually in the top right corner and may show your name or a profile icon. Click on it and select "Account Settings" or "Account" from the dropdown menu.

Find the section labeled "Username" or "Login Information." Click the "Change" or "Edit" button next to your username. Xfinity will ask you to enter your current password to confirm the change. Type in a new username that is between 6 and 32 characters long. You cannot use spaces, and special characters like @, #, $, %, &, or * are not allowed. Numbers and hyphens are fine. Click "Save" or "Confirm," and your new username is active when ready.

Step-by-step: changing your password on xfinity.com

Log into xfinity.com with your current username and password. Open your account menu in the top right corner and select "Account Settings." Look for a section called "Password" or "Security." Click "Change Password" or "Edit."

Xfinity will ask you to enter your current password first. Then type your new password twice to confirm it matches. Your password must be at least 8 characters long. Xfinity does not require special characters, but adding them — like !, @, #, or $ — makes your password stronger and harder to guess. Avoid using your username, your address, or common words. Click "Save" or "Confirm," and the change takes effect right away.

Changing your username or password in the Xfinity mobile app

Open the Xfinity app on your phone and log in if you are not already. Tap the menu icon (usually three horizontal lines) in the bottom right or top left corner, depending on whether you are on iOS or Android. Select "Account" or "My Account."

Look for "Account Settings" or "Login & Security." Tap "Change Username" or "Change Password" depending on what you want to update. Follow the same rules as the website: usernames are 6 to 32 characters with no spaces or special characters, and passwords are at least 8 characters. Confirm your current password when prompted, then save your changes. The app will log you out, and you will need to log back in with your new credentials.

What to do if you forget your new password

If you change your password and then forget it before you write it down, you can reset it without calling Xfinity. Go to xfinity.com and click "Forgot username or password?" on the login page. Xfinity will ask you to enter your username and will then send a password reset link to the email address on file with your account.

Check your email (including your spam folder) for a message from Xfinity. Click the link in the email, and you will be taken to a page where you can create a new password. This link usually works for 24 hours, so act on it the same day you receive it. If you do not see an email within a few minutes, check that you entered your username correctly and that the email address associated with your account is still active.

Why you might want to change your username or password

Change your password regularly — at least once a year — to reduce the risk that someone else has figured it out or found it in a data breach. If you use the same password across multiple websites, change your Xfinity password right away, because a breach at another site could expose your Xfinity account. If you share your login with family members and one of them moves out or you no longer trust them with access, changing your password locks them out when ready.

Change your username if it contains personal information you no longer want visible, if you want something easier to remember, or if you are concerned about privacy. Your username does not have to be an email address — it can be any combination of letters, numbers, and hyphens that meets Xfinity's length and character rules.

Frequently Asked Questions

Does changing my account password change my WiFi password?

No. Your Xfinity account password and your home WiFi password are separate. Changing one does not affect the other. If you need to change your WiFi password, that is a different process done through your router settings or the Xfinity app under WiFi settings.

Can I use an email address as my username?

No. Xfinity usernames cannot contain the @ symbol. You must use a username that is 6 to 32 characters long and contains only letters, numbers, and hyphens. If you prefer to log in with your email, some accounts allow you to use your email as an alternative login method, but your primary username still cannot be an email address.

What if I cannot log into xfinity.com to change my password?

Use the "Forgot username or password?" link on the login page to reset your password via email. If you cannot access the email address on file with your account, or if you do not receive a reset email, contact Xfinity customer service at 1-800-934-6489 and they can verify your identity and reset your password for you.

How long does it take for my new username or password to work?

Changes take effect when ready. You can log out and log back in with your new username or password right away. If you are already logged in when you make the change, you may need to log out and log back in for the new credentials to work across all Xfinity services.
