Change Your WiFi Password Through the Xfinity App or Website

You can change your Comcast Xfinity WiFi password by logging into your account on the Xfinity website or through the Xfinity app on your phone. The process takes about five minutes and does not require you to restart your router or call customer service.

Go to xfinity.com and sign in with your Comcast username and password. Once logged in, look for "Internet" or "WiFi" in the menu, then select "WiFi Settings" or "Manage WiFi". You will see your current network name (SSID) and an option to change the password. Enter your new password — it must be at least 8 characters — and save the change.

If you use the Xfinity app, tap the menu icon, select "Internet", then "WiFi Settings". The steps are the same from there. The new password takes effect within a few minutes, and all your devices will need to reconnect using the new one.

Key Takeaways

  • You change your WiFi password through xfinity.com or the Xfinity mobile app, not by pressing buttons on the router itself.
  • Your new password must be at least 8 characters long and can include letters, numbers, and symbols.
  • The change takes effect within a few minutes, and you will need to reconnect all your devices afterward.
  • If you forget your Comcast account password, you can reset it on the Xfinity login page before you can change your WiFi password.
  • Changing your WiFi password does not affect your internet speed or service — it only changes who can connect to your network.

What Happens to Your Devices After You Change the Password

Once you save the new password, your devices will lose connection to your WiFi network. You do not need to do anything to your router — the change happens on Comcast's servers, not on the device itself.

On each device, go to your WiFi settings, find your network name in the list of available networks, and select it. When prompted, enter your new password. Phones, tablets, laptops, and smart home devices like Alexa or Google Home will all need to reconnect this way. Devices that were previously connected will not automatically reconnect with the old password.

Reset Your Password if You Forget Your Comcast Account Login

If you do not remember the username and password you use to log into Xfinity.com, you cannot change your WiFi password online. You will need to reset your Comcast account password first.

Go to xfinity.com and click "Forgot username or password?" on the login page. Comcast will ask you to verify your identity using your account number, phone number, or email address associated with your account. You can find your account number on your Comcast bill. After you verify your identity, Comcast will send you a link to create a new account password. Once you have reset that password, you can log back in and change your WiFi password.

Change Your WiFi Network Name at the Same Time

While you are in your WiFi settings, you can also change your network name (SSID) — the name that shows up when you look for WiFi networks on your phone or computer. This is optional, but some people change it to something easier to remember or to hide that they use Comcast.

In the same "WiFi Settings" section where you change your password, you will see a field for your network name. You can change it to anything you want, as long as it is 32 characters or fewer. The new network name takes effect at the same time as your new password, so all your devices will need to reconnect.

What to Do if You Cannot Log Into Xfinity.com

If you are having trouble logging into your Comcast account online, try clearing your browser's cache and cookies, or try a different web browser. Sometimes an outdated browser or stored login information causes problems.

If you still cannot log in after trying a different browser, you can call Comcast customer service at 1-800-934-6489 to change your WiFi password over the phone. Have your account number ready. A representative can change the password for you without you needing to log in online, though this usually takes longer than doing it yourself.

Why You Might Want to Change Your WiFi Password

The most common reason to change your WiFi password is if you think someone outside your household has connected to your network without permission. Changing the password will disconnect them and prevent them from reconnecting unless they know the new one.

You might also change your password if you recently had a guest or contractor in your home and gave them your WiFi, or if you are selling or moving out of your house. Changing the password is a straightforward way to make sure only the people you want can use your internet connection.
