Change Your WiFi Password Through the Xfinity App or Website

You can change your Xfinity WiFi password in about five minutes using either the Xfinity My Account app or the website. The process is the same on both — you log in with your Xfinity account credentials, find your gateway (the modem and router combined), and set a new password. The new password takes effect when ready, and all devices will disconnect and need to reconnect using the new one.

The fastest route is the mobile app if you have it installed. Open the Xfinity My Account app, tap the menu icon (three horizontal lines) in the bottom right, select Internet, then tap your gateway. Look for the WiFi settings or WiFi password option — the exact wording varies by app version — and select Change WiFi Password. Type your new password, confirm it, and tap save.

If you prefer the website, go to xfinity.com, sign in to your account, click Internet in the left menu, select your gateway from the list, and look for WiFi settings. The layout is similar to the app, and you will see the option to change the password in the same place.

Key Takeaways

  • You change your WiFi password through the Xfinity My Account app or website, not by pressing buttons on the gateway itself.
  • The new password takes effect when ready, and every device connected to your WiFi will disconnect and need the new password to reconnect.
  • Your WiFi password is separate from your Xfinity account password — changing one does not change the other.
  • If you forget the new password you just set, you can view it again in the same WiFi settings menu where you changed it.

What Happens When You Change the Password

When you save a new WiFi password, your gateway broadcasts it when ready. Every device currently connected — phones, laptops, tablets, smart TVs, smart home devices — will lose the WiFi connection within seconds. You will see a "no internet" message or a disconnected WiFi symbol on each device.

To reconnect, open the WiFi settings on each device, find your network name (also called the SSID), and enter the new password. The network name itself does not change unless you deliberately renamed it — only the password changes. Most devices will reconnect within a minute or two once you enter the correct password.

Smart home devices like thermostats, doorbell cameras, or smart speakers may take longer to reconnect or may require you to remove them from their app and add them back. If a device does not reconnect after five minutes, restart it by unplugging it for 30 seconds, plugging it back in, and trying again.

Choosing a Strong WiFi Password

Xfinity does not enforce a specific password format, but a strong password is at least 12 characters long and includes uppercase letters, lowercase letters, numbers, and symbols. Avoid dictionary words, your name, your address, or anything someone could guess from your social media. A random mix like Kp7$mW2nQx9! is stronger than something like MyDogSpot2024.

Write down your new password somewhere find — a password manager, a locked drawer, or a note on your phone — before you change it. If you forget it, you can view it again in the WiFi settings menu, but having it written down saves you a step if a guest asks for it or you need to reconnect a device weeks later.

If You Cannot Access the Xfinity App or Website

If you do not have internet access (because your gateway is offline or not working), you cannot change the password through the app or website. In this case, you will need to restart your gateway first. Unplug the power cable from the back of the gateway, wait 30 seconds, and plug it back in. The lights will blink for two to three minutes while it restarts.

Once the lights stabilize and you have internet again, you can proceed with changing the password through the app or website. If the gateway does not come back online after restarting, contact Xfinity support — the issue is likely a service outage or a hardware problem, not a password issue.

Resetting Your WiFi Password to the Default

If you change your password and then forget it, you do not need to reset the gateway. straightforward log back into your Xfinity account through the app or website, go to your WiFi settings, and view the current password — it will be displayed in plain text. Write it down or copy it before you close the menu.

If you want to reset the password to the one printed on the back or bottom of your gateway (the default password), you can do that through the same WiFi settings menu. Look for an option like Reset WiFi Password or Use Default Password. This is rarely necessary unless you are troubleshooting a connection problem or preparing to give the gateway to someone else.

Changing the WiFi Network Name (SSID)

The WiFi network name — the one you see when you search for available networks — is separate from the password. If you want to change it from the default XFINITY or XFINITY-5G to something custom, that option is also in the WiFi settings menu. Look for WiFi Network Name or SSID.

Changing the network name does not require a password change, but many people do both at the same time. If you change the network name, devices will see it as a new network and will need to be told to forget the old one and connect to the new one. This process takes a few extra minutes but works the same way as reconnecting after a password change.

Frequently Asked Questions

Will changing my WiFi password affect my Xfinity email or TV service?

No. Your WiFi password is only for connecting devices to the internet wirelessly. Your Xfinity email account, TV service, and account password are separate and will not be affected. Devices that use your WiFi to stream TV or access email will need the new password to reconnect, but the services themselves continue working.

Can I change my WiFi password from my phone if I am away from home?

Yes. As long as you are connected to your Xfinity WiFi or any other internet connection, you can open the Xfinity My Account app or website and change the password remotely. The change takes effect when ready on your gateway at home, and all devices there will disconnect.

How often should I change my WiFi password?

There is no set schedule. Change it if you suspect someone unauthorized is using your network, if you have guests who no longer need access, or if you straightforward want to refresh it. Many people change it once or twice a year as a precaution, but it is not required.

What if my device keeps asking for the password even though I entered it correctly?

Make sure you are typing the exact password — capitals and symbols matter. If you are still stuck, forget the network on that device (go to WiFi settings, find your network, and select "Forget"), then search for it again and re-enter the password. Restarting the device also helps if it is caching an old password.

Can I set different passwords for the 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 allow you to split them into separate networks with different passwords in the advanced WiFi settings, but this is optional. Check your WiFi settings menu to see if this option is available on your gateway.
