Where to change your Xfinity WiFi password

You change your Xfinity WiFi password through the Xfinity My Account app or website, not through your router itself. Log in with your Xfinity username and password, navigate to the Internet section, find your gateway (the device that broadcasts your WiFi), and change the WiFi name and password from there. The change takes effect within a few minutes on all your devices.

You can also call Xfinity customer service at 1-800-934-6489 and ask them to reset your WiFi password over the phone. They will send you a temporary password by text or email, which you can then change to something you prefer through the My Account app.

Key Takeaways

  • The Xfinity My Account app or website is the fastest way to change your WiFi password yourself without calling customer service.
  • Your WiFi password is separate from your Xfinity account password — changing one does not change the other.
  • After you change your password, all devices connected to your WiFi will disconnect and will need the new password to reconnect.
  • If you forget your new password, you can reset it again through My Account or call Xfinity to have them send you a temporary one.

Step-by-step: changing your password through the Xfinity app

Open the Xfinity My Account app on your phone or tablet. If you do not have it, download it from the Apple App Store or Google Play Store. Log in with your Xfinity username and password.

Tap the Internet icon at the bottom of the screen. You will see your gateway listed — this is your WiFi router. Tap on it. Select "WiFi Settings" or "Change WiFi Password." Enter your new password (at least 8 characters, with a mix of uppercase, lowercase, numbers, and symbols for security). Tap "Save" or "Confirm." The app will show a confirmation message within a few seconds.

Your new password is now active. Any device currently connected to your WiFi will disconnect within one to two minutes. When you try to use WiFi on your phone, laptop, or other device, you will be prompted to enter the new password.

Step-by-step: changing your password through the Xfinity website

Go to xfinity.com and log in with your username and password. Click on "Internet" in the top menu. Under "Your Services," find your gateway and click on it. Select "WiFi Settings" or "Manage WiFi."

You will see your current WiFi network name (SSID). Click "Change WiFi Password" next to it. Type your new password in the box. Xfinity will show you password requirements — most commonly 8 characters minimum, with uppercase and lowercase letters. Click "Save Changes."

The website will confirm the change. Your WiFi password is now updated, and devices will need to reconnect using the new password within a few minutes.

What happens to your devices after you change the password

When you change your WiFi password, every device currently connected to your network — phones, laptops, tablets, smart TVs, printers, smart home devices — will lose connection. This usually happens within one to three minutes of the change taking effect.

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 home devices and older devices may take longer to reconnect or may require you to manually re-enter the password in their settings app.

If a device does not reconnect after you enter the correct password, restart it (turn it off and back on). If it still will not connect, forget the network from that device's WiFi settings and reconnect from scratch.

Resetting your password if you forget it

If you change your WiFi password and then forget it, you can reset it the same way you changed it — through the Xfinity My Account app or website. Log in, go to Internet, select your gateway, and view or change your WiFi password again.

If you forget your Xfinity account password (which is different from your WiFi password), you will not be able to log into My Account. Go to xfinity.com, click "Sign In," and select "Forgot Username or Password?" Xfinity will send you a reset link by email or text. After you reset your account password, you can then log in and change your WiFi password.

Difference between your Xfinity account password and WiFi password

Your Xfinity account password is what you use to log into xfinity.com or the My Account app. Your WiFi password is what your guests and devices use to connect to your home network. They are completely separate. Changing one does not change the other.

If someone knows your WiFi password, they can connect to your network but cannot access your Xfinity account or billing information. If someone knows your Xfinity account password, they can log into your account and change your services or billing, but they cannot connect to your WiFi unless you also give them the WiFi password.

Frequently Asked Questions

Can I change my WiFi password from my router directly?

You can, but Xfinity recommends using the My Account app or website instead. If you change it directly on the router, the change may not sync with Xfinity's system, and you could have trouble later. Stick with My Account for the smoothest experience.

How often should I change my WiFi password?

There is no set rule. Change it if you think someone has learned it, if you have had guests over and no longer want them on your network, or if you want to update it for security reasons. Many people change it once or twice a year as a routine precaution.

What if I cannot log into my Xfinity account to change the password?

Call Xfinity customer service at 1-800-934-6489. They can verify your identity and reset your WiFi password for you over the phone. They will send you a temporary password by text or email, which you can then change to something you prefer once you regain access to your account.

Will changing my WiFi password affect my internet speed?

No. Your WiFi password only controls who can connect to your network. Changing it does not change your internet speed or service. If your internet feels slower after a password change, the two events are unrelated — restart your gateway to see if that helps.

Can I have different passwords for 2.4 GHz and 5 GHz networks?

Most Xfinity gateways broadcast both frequencies under the same network name and password by default. Some newer models let you split them into separate networks with different passwords through advanced WiFi settings in My Account. Check your gateway model in My Account to see if this option is available to you.
