Change Your WiFi Password Through the Xfinity App or Website

You can change your Xfinity WiFi password by logging into your account on the Xfinity website or through the Xfinity My Account mobile app. The process takes about five minutes and your new password takes effect within a few minutes on all your devices.

On the website, go to xfinity.com, sign in with your Xfinity username and password, then look for "Internet" or "WiFi Settings" in the menu. On the mobile app, tap the menu icon, select "Internet," then find "WiFi Settings" or "Change WiFi Password." Both routes lead to the same screen where you enter your new password and confirm it.

Your new password must be at least 8 characters long. Xfinity recommends mixing uppercase letters, lowercase letters, numbers, and symbols — something like BlueSky#2024 is stronger than password123. Write down your new password somewhere safe before you confirm the change, because you will need it to reconnect your devices.

Key Takeaways

What Happens to Your Devices After You Change the Password

When you change your WiFi password, every device currently connected to your network will disconnect within a few minutes. Your phone, laptop, tablet, smart TV, and any other connected device will show that the network is available but will not be able to join it until you enter the new password.

You will need to go to each device's WiFi settings, select your Xfinity network name, and type in the new password. On most phones and computers, this takes about 30 seconds per device. Smart home devices like Alexa speakers or Ring doorbells may take longer to reconnect — sometimes up to five minutes — and some may need to be unplugged and plugged back in if they do not reconnect on their own.

Devices that are turned off when you change the password will straightforward prompt you for the new password the next time you turn them on and try to connect. There is no rush to reconnect everything at once.

Reconnecting Your Devices to the New Network

Start with the devices you use most often — your phone and computer. Open WiFi settings, find your Xfinity network name (the same name it had before), tap or click it, and enter your new password exactly as you wrote it. Passwords are case-sensitive, so BlueSky#2024 is different from bluesky#2024.

For smart home devices, check the device's app or manual for reconnection steps. Many smart speakers and cameras have a button you hold down to put them in pairing mode, then you select the network and enter the password through the device's app on your phone. If a device will not reconnect after two attempts, unplug it for 30 seconds, plug it back in, and try again.

Printers and other devices that do not have a screen usually have a settings menu you access through a web browser. Type the printer's IP address into your browser (often printed on a label on the device), find the WiFi settings, and enter your new password there. If you do not know the IP address, check the printer's manual or contact the manufacturer.

If You Forget Your New Password

You can reset your WiFi password through the same Xfinity website or app where you changed it. Log in, go to WiFi Settings, and create a new password. You do not need to remember the old one — Xfinity only requires your account login credentials.

If you cannot remember your Xfinity account password, you can reset that too. On the Xfinity login page, click "Forgot username or password?" and follow the prompts to verify your identity using your phone number, email, or account number. Xfinity will send you a link to create a new account password.

If you are locked out of your account or the online tools are not working, call Xfinity customer service at 1-800-934-6489. They can verify your identity over the phone and reset your WiFi password for you without you needing to log in yourself.

Why You Might Want to Change Your Password Regularly

Changing your WiFi password is a good security practice if you have shared it with guests or contractors who no longer need access, or if you suspect someone outside your household is using your network. A password change when ready disconnects anyone who was using the old password.

You do not need to change your password on any set schedule — once or twice a year is reasonable for most households. If you live alone and have never shared your password, changing it is less urgent. If you run a small business from home or have many guests, changing it once or twice a year makes sense.

Changing your password is also useful if your WiFi is running slowly. Sometimes a neighbor's network or an old device you forgot about can use up your bandwidth. A new password forces every device to reconnect, which can help you spot devices that should not be there.

Changing Your Password on the Xfinity Gateway Device Itself

Most people change their WiFi password through the website or app, but you can also do it directly on your Xfinity gateway (the router box itself). Look for a small button or menu on the device, or open a web browser and type 10.0.0.1 into the address bar, then log in with your gateway username and password.

This method is less common because it requires you to know your gateway's login credentials, which are different from your Xfinity account login. The username and password are usually printed on a sticker on the back or bottom of the gateway. If you cannot find them, the website or app method is simpler.

Changing the password through the gateway itself works the same way as changing it through the website — your new password takes effect within a few minutes and all devices disconnect. There is no advantage to doing it this way unless the website or app is not working.

Frequently Asked Questions

Can I change my WiFi password without logging into my Xfinity account?

No, you need to log in with your Xfinity account username and password to change your WiFi password through the website or app. If you cannot remember your account password, you can reset it on the login page. If you want to avoid logging in, you can change it directly on the gateway device itself, but that requires knowing the gateway's separate login credentials.

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

The password takes effect on Xfinity's servers within a few minutes, but each device needs time to reconnect. Most phones and computers reconnect within 30 seconds to a minute. Smart home devices can take up to five minutes. If a device does not reconnect after five minutes, try unplugging it and plugging it back in.

Will changing my WiFi password affect my internet speed?

No, changing your password does not affect your internet speed. Your speed is determined by your Xfinity plan and the quality of your connection to Xfinity's network, not by your WiFi password. If your speed is slow before the change, it will be slow after the change.

What if my Xfinity gateway has a WPS button — can I use that to change the password?

The WPS button on your gateway is for pairing devices, not for changing your password. Pressing it puts the gateway into pairing mode so devices can connect without entering a password, but it does not change your actual WiFi password. Use the website, app, or gateway settings menu to change your password.

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

Yes, you can change it from anywhere using the Xfinity My Account app or the website on your phone's browser. You do not need to be connected to your home WiFi to make the change — it works over any internet connection. The new password will take effect at your home within a few minutes.
