Change Your WiFi Password in the Xfinity App

The fastest way to change your WiFi password is through the Xfinity app on your phone. Open the app, tap the menu icon (three horizontal lines) in the bottom right, then select "Internet" from the list. You'll see your gateway listed — tap on it, then tap "WiFi Settings" or "WiFi Network Name and Password."

From there, you can change both your network name (SSID) and your password. The password must be at least 8 characters long and can include letters, numbers, and symbols. After you save the new password, your devices will disconnect from the old network and you'll need to reconnect using the new one.

The app method works on both iPhone and Android. If you don't have the Xfinity app installed, you can read it free from the App Store or Google Play Store.

Change Your WiFi Password on the Xfinity Website

You can also change your password by logging into your Xfinity account at xfinity.com. Click "Sign In" in the top right corner and enter your Xfinity username and password. Once you're logged in, look for "Internet" or "My Services" in the main menu.

Select your gateway or modem from the list of devices, then find the WiFi settings option. You'll see fields for your network name and password. Enter your new password (8 characters minimum), then save your changes. Like the app method, your devices will need to reconnect with the new password.

The website method works on any computer or tablet with a web browser, so it's useful if you don't want to install the app.

What Happens to Your Devices When You Change the Password

When you save a new WiFi password, your gateway broadcasts the change when ready. Any device currently connected to your WiFi will lose the connection within a few seconds. Your phone, laptop, tablet, smart TV, and any other connected devices will show that the network is available but will not reconnect automatically.

To reconnect each device, open its WiFi settings, select your Xfinity network by name, and enter the new password. You'll need to do this for every device that was previously connected. Devices you don't use often (like a guest's phone or an old tablet) won't try to reconnect until someone actively uses them.

Reconnecting Your Devices After Changing the Password

Start with the devices you use most often. On a phone or tablet, go to Settings, select WiFi, find your network name, and tap it. When prompted, enter your new password exactly as you typed it — passwords are case-sensitive, so "MyPassword" is different from "mypassword."

On a computer, click the WiFi icon in your system tray (Windows) or menu bar (Mac), select your network, and enter the password. Smart devices like TVs, speakers, or security cameras usually have a WiFi settings menu in their setup or settings app — check the device's manual if you're not sure where to find it.

If a device won't reconnect, try forgetting the network first. On phones and tablets, this is usually an option when you tap your network name. On computers, you may need to go into advanced WiFi settings. Then reconnect as if it's a new network.

If You Can't Access the App or Website

If you've forgotten your Xfinity account password or can't log in, you'll need to reset it before you can change your WiFi password. Go to xfinity.com and click "Sign In," then look for "Forgot username or password?" at the bottom of the login box. Follow the steps to reset your account password using your email address or phone number.

If you don't remember the email or phone number associated with your account, call Xfinity customer service at 1-800-934-6489. They can verify your identity and help you regain access to your account. Once you're logged in again, you can change your WiFi password using either the app or website method.

Why You Might Want to Change Your WiFi Password

You may want to change your password if someone has the old one and you no longer want them to have access, if you've shared it with a guest who no longer visits, or if you straightforward want to use a password that's easier for you to remember. Changing your password doesn't affect your internet service or speed — it only controls who can connect to your network.

If you suspect someone is using your WiFi without permission, changing the password will disconnect them when ready. You can also check which devices are currently connected through the Xfinity app by going to Internet settings and looking for a "Connected Devices" or "Device List" option.

Frequently Asked Questions

Will changing my WiFi password affect my internet speed?

No. Your internet speed depends on your service plan and the Xfinity network, not your WiFi password. Changing the password only controls who can connect to your network — it doesn't change how fast your connection is.

What if I change my password and then forget it?

You can view or change your password again by logging into the Xfinity app or website using the same steps. Your password is stored in your account, so you can always access it or create a new one.

Do I need to restart my gateway after changing the password?

No. Your gateway updates the new password automatically and broadcasts it right away. You don't need to unplug it or restart it — just reconnect your devices with the new password.

Can I change my WiFi password from my phone if I'm not home?

Yes. The Xfinity app works anywhere you have internet access, even if you're not connected to your home WiFi. You can use mobile data to open the app and change your password remotely.

What if my gateway doesn't show up in the app?

Make sure you're signed into the correct Xfinity account — the one associated with your service address. If you have multiple accounts, you may be logged into the wrong one. Sign out and sign back in with the correct username and password.
