Change your WiFi password through the Xfinity app or website

You can change your Xfinity WiFi network password by logging into your Xfinity account online or through the Xfinity mobile app. The process takes about five minutes and applies to the password people use to connect their devices to your home WiFi — not the password you use to log into your Xfinity account itself.

The easiest route is the Xfinity app if you have it installed. Open the app, tap the menu icon (three horizontal lines), select Internet, then tap WiFi Settings. You will see your network name and an option to change the password. Enter a new password of at least 8 characters, then confirm it. The change takes effect when ready, and all devices will need to reconnect using the new password.

If you prefer the website, go to xfinity.com, sign in with your Xfinity username and password, click Internet in the top menu, then select WiFi Settings. The steps are the same: enter your new password and confirm it. You will see a confirmation message when the change is saved.

Key Takeaways

  • You can change your WiFi password through the Xfinity app or at xfinity.com by navigating to WiFi Settings under your Internet account.
  • Your new password must be at least 8 characters long and takes effect when ready after you save it.
  • All devices connected to your WiFi will disconnect and will need to reconnect using the new password.
  • Changing your WiFi password does not affect your Xfinity account login password or any other services.
  • If you cannot access the app or website, you can reset your WiFi password using the reset button on your Xfinity modem or gateway.

What happens to devices when you change the password

When you save a new WiFi password, your modem or gateway broadcasts the change, and all connected devices lose their connection. You will see a "no internet" or "cannot connect" message on phones, laptops, tablets, and smart home devices. This is normal and expected.

To reconnect each device, open its WiFi settings, select your Xfinity network name, and enter the new password. Devices will then reconnect one by one. Smart devices like security cameras, doorbells, or thermostats may take a minute or two to reconnect, so wait a few moments before assuming something is wrong.

Reset your WiFi password using the modem button

If you cannot access the Xfinity app or website, or if you have forgotten your Xfinity account password, you can reset your WiFi password directly on your modem or gateway. Look for a small Reset button on the back or bottom of the device. Press and hold it for 10 to 15 seconds until the lights on the front begin to flash.

The modem will restart and reset to its factory default WiFi password. You can find this default password on a sticker attached to the modem itself — it usually appears as "xfinity" followed by a series of numbers and letters. Once the modem finishes restarting (about two to three minutes), reconnect your devices using this default password, then log into the Xfinity app or website and set a new password of your choice.

Resetting the modem also resets other settings, so you may need to reconfigure port forwarding or other advanced network settings if you had customized them.

Choose a strong WiFi password

A strong WiFi password prevents unauthorized people from connecting to your network and using your internet. Xfinity requires at least 8 characters, but longer passwords are harder to guess. A good approach is to use a mix of uppercase letters, lowercase letters, numbers, and symbols — for example, "BlueSky#2024Home" or "Coffee47!Garden".

Avoid using your name, address, phone number, or other personal information that someone could learn from social media or public records. Also avoid straightforward patterns like "12345678" or "qwerty". If you have a password manager (like Bitwarden, 1Password, or the password manager built into your phone), you can generate and store a random password there so you do not have to remember it.

Troubleshoot if the password change does not work

If you enter a new password but devices still cannot connect, or if you see an error message, first check that you typed the password correctly — passwords are case-sensitive, so "BlueSky" is different from "bluesky". Log out of the Xfinity app or website and log back in, then try changing the password again.

If the change still does not save, restart your modem by unplugging it for 30 seconds, then plugging it back in. Wait for all the lights to stabilize (usually two to three minutes), then try changing the password again through the app or website. If you continue to see an error, contact Xfinity support — there may be a temporary issue with your account or device.

Difference between WiFi password and Xfinity account password

Your WiFi password is what you give to guests or use to connect your phone, laptop, and smart devices to your home internet. Your Xfinity account password is what you use to log into xfinity.com or the Xfinity app to manage your bill, services, and settings. Changing one does not change the other.

If you need to change your Xfinity account password instead, go to xfinity.com, click your account name in the top right, select Account Settings, then choose Change Password. That process is separate from changing your WiFi password and requires you to verify your identity with a security code sent to your email or phone.

Frequently Asked Questions

Do I need to restart my modem after changing the WiFi password?

No, the password change takes effect when ready without a restart. However, if the change does not seem to work, restarting the modem can help. Unplug it for 30 seconds, plug it back in, and wait for the lights to stabilize before reconnecting devices.

What is the default WiFi password if I reset my modem?

The default password is printed on a sticker on your modem or gateway — usually "xfinity" followed by numbers and letters. You can also find it in the Xfinity app under WiFi Settings if you log in with your account credentials.

Can I change my WiFi password from my phone?

Yes, the Xfinity app works on phones and tablets. Open the app, go to Internet, select WiFi Settings, and change the password the same way you would on a computer. The app is available for both iOS and Android.

Will changing my WiFi password affect my internet speed or service?

No, changing the password does not affect your internet speed or service quality. It only changes what password people need to connect to your network. Your modem and service plan remain unchanged.

What if I forgot the new password I just set?

You can view your current WiFi password in the Xfinity app or website by logging into your account and going to WiFi Settings. If you cannot remember your Xfinity account password, use the "Forgot Password" link on the login page to reset it.
