Change your WiFi password through the Xfinity app or website

You can change your Xfinity WiFi password by logging into your account on the Xfinity website or through the Xfinity My Account mobile app. The process takes about five minutes and does not require calling customer service. After you change it, all devices will disconnect and need the new password to reconnect.

The steps are the same whether you use a computer, phone, or tablet. You will need your Xfinity username and password — the same login you use to pay your bill. If you have forgotten that password, you can reset it on the Xfinity sign-in page before you start.

Key Takeaways

  • Log into your Xfinity account on xfinity.com or the My Account app, then go to Internet settings to find your WiFi name and password options.
  • Your new password must be at least 8 characters long and can include letters, numbers, and symbols — avoid spaces and special characters like @ or &.
  • All devices connected to your WiFi will disconnect when ready after you save the new password and will need the new password to reconnect.
  • If you change your password and then cannot reconnect, restart your modem by unplugging it for 30 seconds, then plugging it back in.
  • You can change your WiFi name (SSID) at the same time you change the password if you want a different network name.

Steps to change your password on the Xfinity website

Go to xfinity.com and sign in with your Xfinity username and password. Click on the profile icon in the top right corner, then select "Internet" from the menu. Look for "WiFi Settings" or "WiFi Network Name and Password" — the exact wording varies depending on your modem model.

Click on the option to edit your WiFi password. You will see a field with your current password already filled in. Delete it and type your new password. Make sure it is at least 8 characters long. You can use uppercase letters, lowercase letters, numbers, and symbols like hyphens or underscores, but avoid spaces and special characters that might cause connection problems.

Click "Save" or "explore Changes" at the bottom of the page. Xfinity will ask you to confirm the change. After you confirm, your modem will restart — this usually takes two to three minutes. During this time, your WiFi will be unavailable. Once the restart is complete, you can reconnect using your new password.

Steps to change your password in the Xfinity My Account app

Open the Xfinity My Account app on your phone or tablet and sign in. Tap the menu icon (three horizontal lines) in the bottom right corner. Select "Internet" and then look for "WiFi Settings" or "Manage WiFi."

Tap the option to change your WiFi password. You will see your current password displayed. Tap in the password field and replace it with your new password. Remember that it must be at least 8 characters long. Avoid spaces and special characters that your devices might not recognize.

Tap "Save" or "Done." The app will confirm the change, and your modem will restart. Wait two to three minutes for the restart to finish before you try to reconnect any devices.

What happens to your devices after you change the password

Every device currently connected to your WiFi — phones, tablets, laptops, smart TVs, printers, and anything else — will disconnect when ready when you save the new password. They will not reconnect automatically, even if they remember your old password. You will need to manually reconnect each one.

To reconnect a device, open its WiFi settings, find your Xfinity network name in the list of available networks, select it, and enter your new password. If a device asks whether to forget the old network, select yes. This prevents it from trying to use the old password in the future.

Devices that are turned off or out of range when you change the password will not disconnect. They will straightforward fail to connect the next time you turn them on or bring them back into range. You will need to enter the new password at that point.

Troubleshooting if you cannot reconnect after changing the password

If you changed your password but devices cannot connect, the most common cause is that your modem is still restarting. Wait a full three minutes after you saved the change, then try again. You should see your WiFi network name appear in the available networks list once the restart is complete.

If your network name does not appear after three minutes, restart your modem manually. Unplug the power cable from the back of the modem, wait 30 seconds, and plug it back in. The lights on the front will flash while it restarts — this takes about two to three minutes. Once the lights stop flashing and return to normal, try connecting again with your new password.

If you still cannot connect, double-check that you are typing the new password correctly. Passwords are case-sensitive, meaning uppercase and lowercase letters are different. If you are not sure whether you typed it correctly, go back into your Xfinity account and look at the password field to confirm what you set it to. You can also change it again if you think you made a mistake.

How to change your WiFi network name at the same time

While you are in the WiFi settings, you can also change your network name (called the SSID) if you want something different. This is the name that appears in the list of available networks on your devices. Some people change it to something more descriptive or personal.

In the same WiFi settings screen where you change the password, look for a field labeled "Network Name," "SSID," or "WiFi Name." Click or tap on it and type a new name. Your network name can be up to 32 characters long and can include letters, numbers, spaces, and most symbols. After you change it, save the changes the same way you would for the password.

Your modem will restart again, and all devices will disconnect. When you reconnect, you will see the new network name in your list of available networks instead of the old one.

When to contact Xfinity support

If you cannot log into your Xfinity account on the website or app, you will not be able to change your password yourself. In this case, you can call Xfinity customer service at 1-800-934-6489 and ask them to change your WiFi password for you. Have your account number or the phone number associated with your account ready.

If your modem does not restart after you change the password, or if it restarts but your devices still cannot connect even after you enter the new password correctly, contact Xfinity support. There may be an issue with your modem or account that requires their help to fix.

Frequently Asked Questions

Can I change my WiFi password without restarting my modem?

No. Your modem must restart for the new password to take effect. The restart is automatic and takes two to three minutes. You cannot skip it or delay it.

What if I forget my new WiFi password right after I change it?

Log back into your Xfinity account on xfinity.com or the My Account app and go to WiFi settings. Your current password will be displayed there. You can view it or change it again if you want something easier to remember.

Do I need to change my Xfinity bill payment password when I change my WiFi password?

No. Your WiFi password and your Xfinity account password are separate. Changing one does not affect the other. You only need to change your account password if you want to find your billing information.

Can I change my WiFi password from my phone while I am away from home?

Yes. As long as you have internet access (on cellular data or another WiFi network), you can log into your Xfinity account and change your password from anywhere. You do not need to be connected to your Xfinity WiFi to make the change.

What characters should I avoid in my new WiFi password?

Avoid spaces, quotation marks, and special characters like @, &, %, and $. Stick to letters, numbers, and straightforward symbols like hyphens (-) or underscores (_). Some older devices may have trouble connecting if you use characters they do not recognize.
