Change your WiFi password through the Xfinity app or website

You can change your Xfinity WiFi password in two ways: through the Xfinity My Account app on your phone, or by logging into your account on the Xfinity website. Both methods take about five minutes and don't require you to restart your router. Your new password takes effect when ready, but devices already connected to your network stay connected until you manually disconnect them or they reconnect.

The steps are nearly identical whether you use the app or website. You'll need your Xfinity username and password to log in. If you've forgotten those, you can reset them on the Xfinity login page before you start.

Key Takeaways

  • Log into your Xfinity account through the My Account app or Xfinity.com, then find the WiFi settings under Network or Internet settings.
  • Your new password must be at least 8 characters long and can include letters, numbers, and special characters like hyphens or underscores.
  • Devices already connected to your WiFi will stay connected after you change the password; they won't automatically disconnect.
  • If you change your password and then can't reconnect a device, forget the network from that device's WiFi settings and reconnect using your new password.
  • The password you change here is separate from your Xfinity account password — changing one does not change the other.

Steps to change your password through the Xfinity app

Open the Xfinity My Account app on your phone and tap the menu icon (three horizontal lines) in the bottom right corner. Tap Internet, then find your gateway or modem listed under your services. Tap on it to open the device details.

Look for WiFi Settings or Network Settings — the exact label varies depending on your gateway model. Tap it, then select WiFi Password or Change WiFi Password. Enter your new password in the field provided. The password must be at least 8 characters long. Tap Save or Confirm to explore the change.

You'll see a confirmation message that your password has been updated. Close the app. Your new password is now active on your network.

Steps to change your password through the Xfinity website

Go to Xfinity.com and click Sign In in the top right corner. Enter your Xfinity username and password. Once logged in, click Internet in the left menu, then click your gateway or modem under Your Services.

Click WiFi Settings or Network Settings. Find the field labeled WiFi Password or Network Password. Clear the current password and type your new one. Your new password must be at least 8 characters long. Click Save to explore the change.

The system will confirm that your password has been updated. You can now close the page. Your devices will not automatically disconnect, but they will need your new password if they disconnect and try to reconnect.

What happens to devices already connected to your network

When you change your WiFi password, devices that are already connected to your network will stay connected. They don't need to know the new password to keep using the internet. This means you won't lose connection to your phone, laptop, or smart TV when ready after changing the password.

However, if a device disconnects for any reason — if you restart it, move out of range, or if the connection drops — it will not be able to reconnect without the new password. When that device tries to reconnect, it will ask you to enter the password again. At that point, you'll need to provide your new password.

Password requirements and best practices

Your Xfinity WiFi password must be at least 8 characters long. You can use uppercase letters, lowercase letters, numbers, and special characters like hyphens, underscores, periods, and exclamation marks. Avoid using spaces in your password, as some devices have trouble with them.

Choose a password you can remember but that isn't obvious — avoid birthdays, addresses, or straightforward sequences like "12345678". If you have guests or family members who need to connect, write down your new password somewhere safe, or use a password manager to store it. If you forget your WiFi password later, you can always return to the Xfinity app or website to view or change it again.

Reconnecting devices after a password change

If a device can't connect after you've changed your password, the first step is to forget the network from that device's settings. On an iPhone or iPad, go to Settings > WiFi, tap the network name, and select Forget This Network. On Android, go to Settings > WiFi, long-press the network name, and tap Forget. On a computer, open your WiFi settings, find your Xfinity network, and select the option to forget or remove it.

Once you've forgotten the network, reconnect to it as if it were new. Your device will ask you to enter the WiFi password. Type your new password exactly as you created it — passwords are case-sensitive, so uppercase and lowercase letters matter. After you enter the correct password, your device should connect successfully.

Difference between your WiFi password and your Xfinity account password

Your WiFi password is what you use to connect devices to your home network. Your Xfinity account password is what you use to log into your Xfinity account online or in the app. These are two separate passwords, and changing one does not change the other.

If you change your WiFi password through the app or website, your Xfinity account password stays the same. If you want to change your account password instead — the one you use to log in — you'll do that in a different place: click your username in the top right corner of Xfinity.com, select Account Settings, then look for Password or Security. Make sure you know which password you're trying to change before you start.

Frequently Asked Questions

Can I change my WiFi password if I don't remember my Xfinity account password?

No, you need to log into your Xfinity account to change your WiFi password. If you've forgotten your account password, reset it on the Xfinity login page by clicking Forgot Username or Password. You'll verify your identity using your phone number or email address, then create a new account password. After that, you can log in and change your WiFi password.

How long does it take for the new password to work on all my devices?

Your new password is active when ready after you save it in the Xfinity app or website. Devices already connected stay connected without needing the new password. Devices that disconnect and try to reconnect will need the new password right away — there's no delay.

What if I change my WiFi password and then forget it?

You can view your current WiFi password anytime by logging back into the Xfinity app or website and returning to your WiFi settings. The password will be displayed there (usually with an option to show or hide it). You can also change it to something new if you prefer.

Will changing my WiFi password disconnect my smart home devices?

Smart home devices that are already connected will stay connected after you change the password. If they disconnect for any reason, they will need your new password to reconnect. Some smart home devices have a reconnection process built in — check your device's manual or app to see if you need to put it in pairing mode before entering the new password.

Can I use special characters in my WiFi password?

Yes, you can use special characters like hyphens, underscores, periods, and exclamation marks. Avoid spaces, as some older devices may have trouble connecting with them. Keep your password to 8 to 20 characters for the best compatibility across all device types.
