Change your Xfinity password through the Xfinity app or website

You can change your Xfinity WiFi password in two ways: through the Xfinity app on your phone, or through the Xfinity website on any browser. Both routes take about five minutes and don't require you to restart your modem. The app is faster if you have it installed; the website works if you don't.

Before you start, have your Xfinity username and password ready. This is the login you use to pay your bill or check your account online — not your WiFi password. If you've forgotten it, you can reset it on the Xfinity sign-in page before you begin changing your WiFi password.

Key Takeaways

  • You change your WiFi password through the Xfinity app or at xfinity.com, not through your modem settings.
  • You need your Xfinity account username and password, which is different from your WiFi password.
  • After you change the password, all devices connected to your WiFi will disconnect and need the new password to reconnect.
  • The new password takes effect when ready and does not require a modem restart.
  • If you cannot remember your Xfinity account password, reset it at xfinity.com before changing your WiFi password.

Change your password using the Xfinity app

Open the Xfinity app on your phone and sign in with your Xfinity account username and password. Tap the menu icon (three horizontal lines) at the bottom right of the screen. Select "Internet" from the menu.

Tap "WiFi Settings" or "Manage WiFi". You will see your network name and current password. Tap "Change WiFi Password" or the edit icon next to your password. Enter your new password — it must be at least 8 characters long and can include letters, numbers, and symbols. Tap "Save" or "Confirm". The app will show a confirmation message. Your new password is now active.

Change your password on the Xfinity website

Go to xfinity.com in any browser and sign in with your Xfinity account username and password. Click "Internet" or "Services" in the menu. Look for "WiFi Settings", "Manage WiFi", or "WiFi Network Name and Password".

Click the option to change your WiFi password. You will see a field for your current password and a field for your new password. Enter your new password — it must be at least 8 characters long. Click "Save" or "Update". The website will confirm the change. Your new password is now active on your network.

What happens after you change your password

All devices currently connected to your WiFi will disconnect within a few seconds. Your phone, laptop, tablet, smart TV, and any other connected devices will show that the WiFi network is no longer available. This is normal and expected.

To reconnect each device, open its WiFi settings, select your Xfinity network name, and enter your new password. Devices will reconnect one at a time. You do not need to restart your modem or do anything else — the password change takes effect when ready.

If you forgot your Xfinity account password

You cannot change your WiFi password without signing into your Xfinity account first. If you've forgotten your Xfinity username or password, go to xfinity.com and click "Forgot username or password?" on the sign-in page. Follow the prompts to reset it using your email address or phone number.

Xfinity will send you a link or code to reset your account password. Complete that process, then return to WiFi settings to change your WiFi password. This takes an extra 5 to 10 minutes but only needs to happen once.

Create a strong WiFi password

When you set your new password, use a combination of uppercase letters, lowercase letters, numbers, and symbols. Avoid using your name, address, phone number, or other personal information. A strong password is harder for someone nearby to guess or crack.

Write down your new password and store it somewhere safe — a notebook, a password manager, or a note on your phone. You will need it every time a new device connects to your WiFi, and you may forget it months or years from now. Xfinity does not send you a copy of your WiFi password by email or text, so keeping your own record is important.

Troubleshooting if the change doesn't work

If you change your password but devices still cannot connect, wait 30 seconds and try again. Sometimes the network takes a moment to update. If a device still cannot connect after 30 seconds, forget the network in that device's WiFi settings and reconnect using the new password.

If the Xfinity app or website shows an error when you try to save your new password, check that your password is at least 8 characters long and does not contain only numbers or only letters. If the error continues, sign out of the app or website, close it completely, and try again. If you still see an error, contact Xfinity support at 1-800-934-6489 or through the app's help section.

Frequently Asked Questions

Do I need to restart my modem after changing my WiFi password?

No. Your modem does not need to restart. The new password takes effect when ready. You only need to reconnect each device using the new password.

Can I change my WiFi password from my modem's settings page?

No. Xfinity WiFi passwords must be changed through the Xfinity app or website, not through your modem's admin page. If you try to change it in your modem settings, the change may not save or may not sync with your Xfinity account.

What if I change my password and then forget it?

You can change it again using the same steps. Sign into the Xfinity app or website, go to WiFi settings, and set a new password. There is no limit to how many times you can change it.

Will changing my WiFi password affect my internet speed?

No. Changing your password does not change your internet speed or service. It only changes the password people need to connect to your network.

Can I change my WiFi password on a guest network?

Yes. In WiFi settings, you will see options for your main network and any guest networks you have created. You can change the password for each one separately using the same process.
