Change your Xfinity WiFi password through the Xfinity My Account app or website, or by calling Xfinity customer service

You can change your WiFi password yourself using the Xfinity My Account app (available on iOS and Android) or the website at xfinity.com. Both routes take about five minutes and require you to sign in with your Xfinity account username and password. If you do not have access to the app or website, or if you forget your account password, you can call Xfinity customer service at 1-800-934-6489 and a representative will walk you through the change over the phone.

The method you choose depends on what is most convenient for you. The app and website are fastest if you have your account password ready. The phone option works if you prefer speaking to someone or if you cannot access the app or website for any reason.

Key Takeaways

  • The fastest way to change your WiFi password is through the Xfinity My Account app or website, which takes about five minutes and requires no phone call.
  • Your new password must be between 8 and 63 characters and can include letters, numbers, and special characters.
  • After you change the password, all devices currently connected to your WiFi will disconnect and will need the new password to reconnect.
  • If you cannot remember your Xfinity account password, you can reset it on the Xfinity login page before changing your WiFi password.

Change your password through the Xfinity My Account app

Open the Xfinity My Account app on your phone or tablet and sign in with your Xfinity username and password. Tap the menu icon (three horizontal lines) in the bottom right corner, then select "Internet" or "WiFi Settings." Look for an option labeled "Change WiFi Password" or "WiFi Settings" — the exact wording varies depending on your app version.

Tap that option and enter your new password. Xfinity will show you the password requirements: it must be between 8 and 63 characters long and can include uppercase and lowercase letters, numbers, and special characters like hyphens or underscores. After you enter your new password, tap "Save" or "Confirm." The app will show a confirmation message within a few seconds. All devices connected to your WiFi will disconnect immediately, and you will need to reconnect them using the new password.

Change your password through the Xfinity website

Go to xfinity.com and sign in with your Xfinity username and password. Once you are logged in, look for a section labeled "Internet," "WiFi," or "My Services" — the exact location depends on which version of the website you see. Click on "WiFi Settings" or "Change WiFi Password."

You will see a field showing your current WiFi network name (SSID). Below that, enter your new password. Remember that it must be 8 to 63 characters and can include letters, numbers, and special characters. Click "Save" or "Apply." The website will confirm the change, usually within seconds. Your WiFi network will restart, and all connected devices will need to reconnect with the new password.

Change your password by phone with Xfinity customer service

Call Xfinity customer service at 1-800-934-6489. A representative will ask you to verify your account by providing your account number, phone number, or the last four digits of the Social Security number on file. Once verified, tell the representative you want to change your WiFi password.

The representative will either change the password for you and read it back, or they will guide you through changing it yourself using the app or website while you are on the call. If they change it for you, write down the new password immediately. As with the other methods, all devices will disconnect and need the new password to reconnect.

What happens to your devices after you change the password

When you change your WiFi password, your Xfinity modem and router will restart. This usually takes one to three minutes. During that time, no devices will have internet access. Once the restart is complete, any device that was previously connected to your WiFi network will show that it cannot connect — it will either display an error or show the network as available but requiring a password.

To reconnect each device, open its WiFi settings, select your Xfinity network name, and enter the new password. Phones, tablets, laptops, smart TVs, and other devices will all need to do this. Some devices may have the old password saved and will try to reconnect automatically; when that fails, you will need to "forget" the network and reconnect with the new password.

If you forget your Xfinity account password

You cannot change your WiFi password without signing into your Xfinity account first. If you forget your account password, go to xfinity.com and click "Sign In" at the top of the page. Below the login fields, click "Forgot username or password?" Xfinity will ask you to enter your account number or the phone number associated with your account.

You will then be asked to verify your identity by answering security questions or receiving a code via email or text message. Once verified, you can create a new account password. After that, you can sign in and change your WiFi password using either the app or website method described above.

If you cannot access the app or website

If the Xfinity My Account app is not working or you cannot reach xfinity.com, calling customer service is your best option. Have your account number ready when you call 1-800-934-6489. A representative can change your WiFi password without requiring you to use the app or website.

You can also visit an Xfinity store in person if one is near you. A staff member can change the password on your account while you are there. To find a store location, go to xfinity.com and search for "store locator," or call the customer service number above and ask for the nearest location.

Frequently Asked Questions

Will changing my WiFi password affect my internet speed or connection quality?

No. Changing your password does not change your internet speed or the quality of your connection. It only changes the password people need to enter to connect to your network. Once devices reconnect with the new password, they will work exactly as they did before.

Can I change my WiFi password from a device that is not connected to my WiFi?

Yes. You can change your password using the Xfinity My Account app or website from any device with internet access — a phone on cellular data, a computer on a different WiFi network, or a tablet at a coffee shop. You only need to sign into your Xfinity account; you do not need to be connected to your own WiFi network.

What should I do if the app or website says my password change failed?

Wait a few minutes and try again. If the error continues, restart your modem by unplugging it for 30 seconds, then plugging it back in. Wait for it to fully restart (usually two to three minutes), then try changing the password again. If it still does not work, call Xfinity customer service at 1-800-934-6489.

Can I change my WiFi password if I do not remember my network name?

Yes. When you sign into your Xfinity account through the app or website, the system will show you your network name. You do not need to know it in advance. The network name is also printed on the label attached to your Xfinity modem and router.

How often should I change my WiFi password?

There is no required schedule. Many people change their password once or twice a year as a security practice, or whenever they suspect someone unauthorized has connected to their network. You can change it as often as you want using any of the methods described above.
