Change your Xfinity password through your online account in three steps

The fastest way to change your Xfinity password is through the Xfinity website or mobile app. Go to xfinity.com, sign in with your current username and password, then look for "Account" or "My Account" in the top menu. Select "Security" or "Password" (the exact wording shifts between the website and app). Enter your current password once to verify it's you, then type your new password twice — once to create it, once to confirm. The change takes effect when ready.

Your new password must be at least 8 characters long and include at least one uppercase letter, one lowercase letter, one number, and one special character like ! or @. Xfinity will reject passwords that contain your username or parts of your email address. If you forget what you just set, you can change it again the same way — there's no waiting period between changes.

If you use the Xfinity mobile app instead of the website, the steps are identical. Open the app, tap the menu icon (three horizontal lines), go to "Account," then "Security," then "Password." The app sometimes takes a few seconds longer to process the change than the website does, but the result is the same.

Key Takeaways

  • Sign into xfinity.com or the Xfinity app, navigate to Account > Security > Password, and enter your current password followed by your new password twice.
  • Your new password must be at least 8 characters and include uppercase letters, lowercase letters, numbers, and a special character.
  • If you cannot sign in because you forgot your password, use the "Forgot username or password?" link on the Xfinity login page to reset it by email or phone number.
  • Changes take effect when ready, and you will need to sign in again on any device where you were previously logged in.
  • If you change your password and then cannot sign in, wait a few minutes — the system sometimes needs time to sync across Xfinity's servers.

Reset your password by email or phone if you cannot sign in

If you cannot remember your current password, you cannot use the method above. Instead, go to xfinity.com and click "Forgot username or password?" below the sign-in box. Xfinity will ask you to enter the email address or phone number associated with your account.

Choose whether you want a reset link sent to your email or a code sent by text message. If you choose email, check your inbox (and spam folder) for a message from Xfinity. The link in that email will take you to a page where you can create a new password. If you choose text, you will receive a six-digit code that you enter on the Xfinity website to proceed. Both methods work equally well — pick whichever you have faster access to.

The reset link or code expires after 24 hours. If you do not use it within that window, you will need to start the process again. Once you create your new password through the reset page, sign out of all your devices and sign back in with the new password.

Change your password over the phone with Xfinity customer service

If you prefer not to change your password online, you can call Xfinity customer service at 1-800-XFINITY (1-800-934-6489). Have your account number or the phone number associated with your account ready. The representative will verify your identity by asking security questions — usually the last four digits of your Social Security number, your billing address, or the answer to a security question you set up when you created your account.

Once verified, tell the representative you want to change your password. They cannot set a new password for you directly — instead, they will send a password reset link to your email or a code to your phone number on file. You will then follow the same process as the email or text reset described above. This method takes longer than changing it yourself online, but it works if you do not have access to your email or phone number.

Wait times to reach Xfinity customer service vary widely depending on the time of day and day of the week. Calling early in the morning on a weekday usually means a shorter wait than calling in the evening or on weekends.

What happens to your devices after you change your password

When you change your Xfinity password, you are not automatically signed out of devices where you were already logged in. This means your phone, tablet, computer, or streaming device will continue to work without interruption. However, the next time you try to sign in on any device — or the next time that device needs to re-authenticate, which can happen weeks or months later — you will need to enter your new password.

If you want to sign out of all devices when ready after changing your password, go back to Account > Security on the Xfinity website and look for an option that says "Sign out all devices" or "Active sessions." Not all account types show this option, but if yours does, clicking it will force every device to sign out at once. You will then need to sign back in on each device with your new password.

Protect your new password from the start

Do not share your Xfinity password with anyone, including family members, roommates, or Xfinity employees. Xfinity customer service will never ask you to tell them your password over the phone or in an email. If someone claiming to be from Xfinity asks for your password, hang up or delete the message — it is a scam.

Store your password in a password manager like Bitwarden, 1Password, or the password manager built into your phone or browser. These tools remember your password for you so you do not have to write it down or reuse the same password across multiple accounts. If you use the same password for Xfinity, email, banking, and social media, changing one password does not protect you if one of those other accounts is breached.

Change your Xfinity password at least once a year, or when ready if you suspect someone else knows it. If you share your Xfinity login with a family member who no longer lives with you or who should no longer have access, change your password right away — they will be signed out the next time they try to use it.

Troubleshoot if your password change does not work

If you try to change your password on xfinity.com and get an error message, try these steps in order. First, sign out completely and wait two minutes, then sign back in and try again. Sometimes the Xfinity website gets stuck in a temporary state that a full sign-out clears.

Second, try a different web browser. If you normally use Chrome, try Firefox or Safari instead. Browser extensions or cached data can sometimes interfere with the password change page. If the change works in a different browser, clear your cache and cookies in your usual browser, then try again.

Third, if you are using the Xfinity mobile app, try the website instead, or vice versa. One sometimes works when the other does not. If neither works after waiting a few minutes, call Xfinity customer service at 1-800-XFINITY. They can check whether your account has a temporary lock or other issue preventing password changes, and they can send you a reset link as a workaround.

Frequently Asked Questions

How often should I change my Xfinity password?

Change it at least once a year as a routine practice. Change it when ready if you think someone else knows it, if you used the same password on another account that was breached, or if you shared your login with someone who should no longer have access. You can change it as often as you want — there is no limit.

Can I use the same password for Xfinity and my email?

You can, but it is not a good idea. If someone breaks into one account, they can use the same password to break into the other. Use a different password for each service. A password manager makes this easier by remembering all of them for you.

What if I change my password and then forget it right away?

Use the "Forgot username or password?" link on the Xfinity login page to reset it. You can do this as many times as you need. There is no penalty for resetting your password frequently.

Will changing my password affect my internet or TV service?

No. Changing your Xfinity account password does not affect your internet speed, TV channels, or service quality. It only affects which devices can sign into your account online.

Can I change my password if I am locked out of my account?

If your account is locked due to too many failed sign-in attempts, you will need to wait 30 minutes before trying again, or use the "Forgot username or password?" link to reset it by email or phone. If your account is locked for another reason, call Xfinity customer service to unlock it first.
