Change your WiFi password through the Xfinity app or website in under five minutes

You can change your Xfinity WiFi password by logging into your Xfinity account online, opening the Gateway settings, and entering a new password. The fastest route is the Xfinity My Account app on your phone. You can also do it from a web browser at xfinity.com. The change takes effect when ready on new devices trying to connect; devices already connected stay online until you restart the gateway or they disconnect on their own.

Your WiFi password is separate from your Xfinity account password. Changing one does not change the other. If you have forgotten your current WiFi password, you can see it in the same place you change it — you do not need to reset the gateway or call support.

Key Takeaways

  • Log into your Xfinity account at xfinity.com or use the Xfinity My Account app, then find Gateway Settings to change your WiFi password.
  • Your WiFi password and your Xfinity account password are two different things; changing one does not affect the other.
  • The new password takes effect right away for new connections, but devices already connected will stay online until they disconnect or you restart the gateway.
  • If you have forgotten your WiFi password, you can view it in the same Gateway Settings menu without resetting anything.

Using the Xfinity My Account app on your phone

Open the Xfinity My Account app and sign in with your Xfinity username and password. Tap the menu icon (three horizontal lines) in the bottom right corner, then select "Services." Find your gateway or modem in the list and tap on it.

Look for "WiFi Settings" or "WiFi Password" and tap it. You will see your current network name and password. Tap "Change WiFi Password" and enter a new one. The app will ask you to confirm the new password by typing it again. Tap "Save" or "Confirm," and the change is live.

Using the Xfinity website on a computer or tablet

Go to xfinity.com and sign in with your username and password. Click on "Services" or "Internet" in the menu. Find your gateway or modem and click on it to open its settings page.

Look for "WiFi Settings" or "Gateway Settings." Click on the WiFi network name (SSID) or the option to change your password. Enter your new password in the field provided, confirm it by typing it again, and click "Save" or "explore." The change takes effect within a few seconds.

What happens to devices already connected to your WiFi

Devices that are already connected to your WiFi will not be kicked off when ready when you change the password. They will stay online until they disconnect, go to sleep, or you manually restart the gateway. However, if a device disconnects for any reason — moving out of range, going into airplane mode, or a network hiccup — it will need the new password to reconnect.

If you want all devices to use the new password right away, restart your Xfinity gateway. Unplug it for 30 seconds, then plug it back in. Wait about two minutes for it to fully restart. All devices will disconnect and will need the new password to reconnect.

Password requirements and best practices

Xfinity requires WiFi passwords to be at least 8 characters long. You can use uppercase letters, lowercase letters, numbers, and some special characters like hyphens and underscores. Avoid spaces in your password, as some devices have trouble connecting with them.

Choose a password you can remember but that is not straightforward to guess. Avoid using your name, address, or birthdate. A mix of letters and numbers works well. If you write it down, keep the paper in a safe place — not on a sticky note on your router.

If you cannot find the WiFi settings in your account

Make sure you are signed into the account that owns the gateway. If you share an Xfinity account with a family member, only the primary account holder can change WiFi settings. If you are not the primary account holder, ask the person who is to make the change.

If you are the primary account holder and still cannot find the WiFi settings, your gateway may be too old to support remote password changes through the app or website. In that case, you can change the password directly on the gateway itself using a computer or phone connected to your WiFi. Open a web browser and go to 10.0.0.1, then sign in with "admin" as the username and your gateway's default password (usually printed on the back of the device). Look for WiFi settings and change the password there.

Your WiFi password versus your Xfinity account password

These are two separate passwords and serve different purposes. Your Xfinity account password is what you use to sign into xfinity.com or the Xfinity app to manage your bill, view your account, and change settings. Your WiFi password is what guests and devices use to connect to your home network.

If you change your WiFi password, your Xfinity account password stays the same. If you change your Xfinity account password, your WiFi password is not affected. If you have forgotten your Xfinity account password, you can reset it on the Xfinity sign-in page by clicking "Forgot username or password?" That is a separate process from changing your WiFi password.

Frequently Asked Questions

Can I see my current WiFi password if I forgot it?

Yes. Log into your Xfinity account and go to Gateway Settings or WiFi Settings. Your current password will be displayed there. You do not need to reset the gateway or call support. If you cannot see it in the app or website, use the method described above to access the gateway directly at 10.0.0.1.

How long does it take for the new password to work?

The new password takes effect within seconds. Devices already connected stay online until they disconnect. New devices trying to connect will need the new password right away. If a device is having trouble connecting with the new password, restart the device or "forget" the WiFi network and reconnect manually.

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

No, you do not need to restart it. The change is live when ready. You only need to restart the gateway if you want to force all currently connected devices to disconnect and reconnect with the new password.

What if I change my password and a device still will not connect?

Go to your device's WiFi settings, find your network name, and select "Forget this network." Then reconnect and enter the new password. If that does not work, restart the device. If the problem continues, restart your gateway by unplugging it for 30 seconds.

Can someone else change my WiFi password if they know my Xfinity account password?

Yes, anyone with access to your Xfinity account can change your WiFi password through the app or website. Keep your Xfinity account password private. If you share a device with someone, sign out of your Xfinity account when you are done, or use a separate account on that device.
