Change your WiFi password through the Xfinity app or website

You can change your WiFi network password by logging into your Xfinity account online or through the Xfinity mobile app. The process takes about five minutes and does not require a technician visit. After you change it, all devices will need the new password to reconnect.

The steps are the same whether you use a computer, phone, or tablet. You will need to know your Xfinity username and password to log in — this is different from your WiFi password. If you have forgotten your Xfinity account password, you can reset it on the Comcast login page before you start.

Key Takeaways

  • Log into your Xfinity account at xfinity.com or through the Xfinity app, then navigate to the WiFi settings section to change your network password.
  • Your new WiFi password must be at least 8 characters long and can include uppercase letters, lowercase letters, numbers, and symbols.
  • After you save the new password, your internet connection will briefly drop, and all connected devices will disconnect and need to reconnect with the new password.
  • If you cannot log into your Xfinity account, reset your account password first at xfinity.com before attempting to change your WiFi password.

Steps to change your password on 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" or "WiFi" section in the menu — the exact name varies depending on your account type. Click on it to open your internet settings.

Find the option labeled "WiFi Settings" or "Manage WiFi." This will show you your current network name (SSID) and a button or link to change the password. Click the change password button. Enter your new password in the field provided. Make sure your password is at least 8 characters long — Xfinity will tell you if it is too short. You can use letters, numbers, and symbols. Click "Save" or "Confirm" to explore the change.

Your modem and router will restart automatically to explore the new password. This takes about two to three minutes. During this time, your internet will be unavailable. Once the restart is complete, your WiFi network will be live with the new password.

Steps to change your password in the Xfinity mobile app

Open the Xfinity app on your phone or tablet and sign in with your Xfinity username and password. Tap the menu icon (three horizontal lines) in the bottom right corner. Select "Internet" or "Services" from the menu.

Look for "WiFi Settings" or "Manage WiFi Network." Tap on it. You will see your current network name and a button to change the password. Tap "Change Password" or the edit icon next to your network name. Enter your new password — it must be at least 8 characters. Tap "Save" or "Confirm."

The app will show a message that your modem is restarting. Wait two to three minutes before trying to reconnect any devices. Your WiFi will come back online with the new password once the restart is complete.

What to do after you change your password

Once your modem has restarted and your WiFi is back online, you will need to reconnect every device that was previously connected to your network. This includes phones, tablets, laptops, smart TVs, printers, and any other WiFi-enabled devices.

On each device, open the WiFi settings and look for your network name in the list of available networks. Select it and enter your new password when prompted. The device will connect and should stay connected as long as the password is correct. If a device does not connect on the first try, forget the network and reconnect — this clears any cached version of the old password.

If you have a guest network enabled on your Xfinity account, the guest password is separate from your main WiFi password. Changing your main password does not affect the guest network, so guests will still be able to use the old guest password until you change that separately.

Password requirements and best practices

Xfinity requires your WiFi password to be at least 8 characters long. You can use uppercase letters, lowercase letters, numbers, and symbols. Avoid using your Xfinity account password as your WiFi password — keep them separate so that if someone learns your WiFi password, they cannot access your account.

Choose a password that is hard to guess but straightforward for you to remember. Avoid common words, birthdays, or sequences like "12345678." A mix of letters and numbers works well — for example, "Blue7Maple9" is stronger than "password123." Write it down in a find place if you think you might forget it.

Troubleshooting if the change does not work

If you see an error message when you try to save your new password, check that it meets the length requirement (at least 8 characters) and does not contain characters that Xfinity does not allow. Try removing any special symbols and use only letters and numbers.

If you cannot log into your Xfinity account to reach the WiFi settings, you may need to reset your account password first. Go to xfinity.com and click "Forgot Username or Password?" Follow the steps to reset your account password, then log back in and try changing your WiFi password again.

If your modem does not restart after you save the new password, wait five minutes and then restart it manually by unplugging it for 30 seconds and plugging it back in. This forces a restart and allows the new password to take effect.

Frequently Asked Questions

Will changing my WiFi password disconnect my internet?

Yes, your internet will briefly go offline while your modem restarts — usually two to three minutes. Plan the change for a time when you do not need internet access. After the restart, your WiFi will be back online with the new password.

Can I change my WiFi password without changing my Xfinity account password?

Yes. Your WiFi password and your Xfinity account password are separate. Changing one does not affect the other. You can change your WiFi password as often as you want without touching your account password.

What if I forget my new WiFi password?

Log back into your Xfinity account at xfinity.com or through the app and go to WiFi Settings. You can view your current password there or change it to something new. You do not need to contact Xfinity support to recover a forgotten WiFi password.

Do I need to change my WiFi password if I change my Xfinity account password?

No. Changing your Xfinity account password does not change your WiFi password. They are independent of each other. You only need to change your WiFi password if you want to update the network security or if you suspect someone has learned your current WiFi password.

Can I change my password on a guest network separately?

Yes. If you have a guest network enabled, it has its own separate password. You can change the guest password through the same WiFi Settings section in your Xfinity account. Changing the guest password does not affect your main network password.
