Change your Xfinity WiFi password through the Xfinity My Account app or website

You can change your Xfinity WiFi password in about five minutes using either your phone or computer. The fastest way is through the Xfinity My Account app if you already have it installed. If you do not have the app, you can log into your account at xfinity.com on any web browser. Both methods take you to the same place and work the same way — you will need your Xfinity username and password to get your free guide.

Changing your password does not affect your internet connection or any other Xfinity services. Your devices will simply need to reconnect to the WiFi network using the new password once you have made the change. This is a good time to change your password if you have shared it with people who no longer need access, or if you want to strengthen your network security.

Key Takeaways

  • You can change your WiFi password through the Xfinity My Account app or at xfinity.com using your Xfinity username and password.
  • The change takes effect immediately, and all your devices will need to reconnect using the new password.
  • Your new password must be at least 8 characters long and can include letters, numbers, and special characters.
  • If you forget your new password, you can view it again in the My Account app under WiFi settings at any time.

Change your password using the Xfinity My Account app

Open the Xfinity My Account app on your phone and sign in with your Xfinity username and password. Tap the menu icon (three horizontal lines) in the bottom right corner, then select Internet. Look for the option labeled WiFi Settings or Manage WiFi — the exact wording depends on your app version.

Tap on your network name (SSID), then select Change WiFi Password. Enter your new password in the field provided. Xfinity requires passwords to be at least 8 characters long, but longer passwords are stronger. You can use uppercase letters, lowercase letters, numbers, and special characters like exclamation marks or hyphens. Tap Save or Confirm to apply the change.

Your new password is now active. Any device currently connected to your WiFi will stay connected, but the next time it disconnects or you restart it, you will need to enter the new password to reconnect. Devices that were previously connected but are not currently online will also need the new password when they next try to join the network.

Change your password through the Xfinity website

Go to xfinity.com and sign in with your Xfinity username and password. Once you are logged in, look for the Internet section or a menu option labeled Services. Click on WiFi Settings or Manage WiFi. You may need to click on your gateway or modem model name to see the WiFi options.

Find your network name (SSID) in the list and click on it. Select the option to change or edit your WiFi password. Enter your new password — remember that it must be at least 8 characters long. Click Save or Apply to confirm the change. The website will show a confirmation message when the change has been saved.

What to do if you cannot find the WiFi settings

If you are logged into your Xfinity account but cannot locate the WiFi settings, check that you are in the right section. On the website, make sure you have selected Internet from the main menu, not TV or Voice. In the app, tap the menu icon and confirm you have selected Internet before looking for WiFi Settings.

If you still cannot find it, your account may not have the permissions needed to change WiFi settings. This sometimes happens if the account is managed by someone else or if there is a restriction on the account. Contact Xfinity support at 1-800-934-6489 to confirm that your account can change the password, or ask them to make the change for you.

Reconnect your devices after changing the password

After you change your WiFi password, your devices will not automatically know the new one. Go to each device's WiFi settings, find your Xfinity network name, and select it. When prompted, enter your new password. The device will then reconnect and stay connected as long as the password is correct.

If a device says the password is incorrect even though you entered it correctly, double-check that you are typing it exactly as you set it — passwords are case-sensitive, meaning uppercase and lowercase letters are different. If you are still having trouble, you can view your password again in the My Account app to confirm what you set it to.

Create a strong password you can remember

A strong WiFi password makes it harder for someone to guess or crack your network. Avoid using simple patterns like "12345678" or common words like your street name or pet's name. Instead, mix uppercase and lowercase letters with numbers and special characters — for example, "BlueSky#2024Home" is stronger than "bluesky2024".

Write your new password down and store it somewhere safe, like a password manager or a locked drawer. This way you will have it if you need to reconnect a device later or give access to a guest. Do not share your password through email or text message — if someone needs to connect, tell them the password in person or over the phone.

Frequently Asked Questions

Will changing my WiFi password disconnect me from the internet?

No. Your internet connection itself will not be affected. You will stay online on whatever device you are using to make the change. Other devices will stay connected until they disconnect or restart, at which point they will need the new password to reconnect.

What if I forget my new WiFi password?

You can view your current WiFi password at any time by going back into the My Account app or website and looking at your WiFi settings. The password will be displayed there, usually with an option to show or hide it. You do not have to reset it if you simply forgot what you set it to.

Can I change the WiFi network name (SSID) at the same time?

Yes. In the WiFi settings, you will usually see an option to edit both the network name and the password. Changing the network name is optional, but some people do it to make their network easier to identify or to hide it from appearing in the available networks list.

How long does it take for the password change to take effect?

The change is immediate. As soon as you save it in the app or website, the new password is active. Devices that are currently connected will stay connected, but any device that disconnects will need the new password to rejoin.

Do I need to restart my modem or router after changing the password?

No. You do not need to restart anything. The password change happens on Xfinity's servers and takes effect right away without any restart required on your end.
