Change Your WiFi Password Through the Xfinity App or Website

You can change your Xfinity WiFi password by logging into your account through the Xfinity My Account app or the Xfinity.com website. Both routes take about five minutes and let you set a new password when ready without calling support or waiting for a technician.

The password you change here is the one you enter on your phone, laptop, or other devices when you connect to your home WiFi network — not your Xfinity account login password. Changing it does not affect your bill, your internet speed, or any other service. All devices currently connected will stay connected, but new devices will need the new password to join the network.

Key Takeaways

  • You can change your WiFi password through the Xfinity My Account app or Xfinity.com without calling support.
  • The password change takes effect when ready, but devices already connected stay connected until they disconnect.
  • Your WiFi network name (SSID) and password are printed on the back or bottom of your Xfinity modem and router.
  • If you forget your new password, you can view it again in the My Account app or website under WiFi settings.
  • Changing your password does not reset your modem or interrupt your internet service.

Steps to Change Your Password on the Xfinity App

Open the Xfinity My Account app on your phone or tablet. If you do not have it, read it from the Apple App Store or Google Play Store. Tap the menu icon (three horizontal lines) in the bottom right corner, then select Internet.

Tap WiFi Settings, then tap Change WiFi Password. Enter your new password — it must be at least 8 characters long and can include uppercase letters, lowercase letters, numbers, and symbols. Tap Save. The app will confirm the change within a few seconds.

After you change the password, you will need to reconnect any device that was previously connected to your WiFi. Go to your device's WiFi settings, select your Xfinity network name, and enter the new password when prompted.

Steps to Change Your Password on Xfinity.com

Go to Xfinity.com and sign in with your Xfinity username and password. Click Internet in the top menu, then click WiFi Settings. Look for the option labeled Change WiFi Password or Manage WiFi.

Enter your new password in the field provided. The password must be at least 8 characters and can include letters, numbers, and symbols. Click Save or Update. You will see a confirmation message once the change is complete.

Like the app, the website change takes effect when ready. Devices that were connected before the change will lose their connection and will need to reconnect using the new password.

What Happens to Devices After You Change the Password

Devices that are currently connected to your WiFi will remain connected and will continue to work normally. They do not automatically disconnect when you change the password. However, if a device disconnects for any reason — such as going out of range or being turned off — it will not be able to reconnect without the new password.

To reconnect a device after changing your password, go to your device's WiFi settings, find your Xfinity network name, and select it. When prompted to enter the password, type your new password. The device will then connect to the network.

Finding Your WiFi Network Name and Password

Your WiFi network name (also called the SSID) and the default password are printed on a sticker attached to your Xfinity modem and router. Look on the back or bottom of the device. The sticker usually shows a network name that starts with "XFINITY" or "XFINITY-" followed by numbers or letters.

If you have changed your password before and cannot remember the new one, you can view it in the Xfinity My Account app or website under WiFi Settings. You do not need to reset your modem to see it. If you have lost access to your Xfinity account, call Xfinity customer service at 1-800-934-6489 to verify your identity and retrieve your password.

Troubleshooting Connection Problems After Changing Your Password

If a device will not connect after you enter the new password, first check that you are typing the password correctly — passwords are case-sensitive, meaning capital letters and lowercase letters are different. Verify the password by checking it again in the Xfinity My Account app or on the sticker on your modem.

If the password is correct but the device still will not connect, try "forgetting" the network on your device and reconnecting. On most phones and computers, go to WiFi settings, select your Xfinity network, and choose "Forget" or "Remove". Then select the network again and enter the new password. If the problem continues, restart your modem by unplugging it for 30 seconds, plugging it back in, and waiting two minutes for it to fully restart.

Frequently Asked Questions

Will changing my WiFi password affect my internet speed or service?

No. Changing your WiFi password only changes the password guests and devices use to connect to your network. It does not affect your internet speed, your service plan, or your bill. Your modem and router continue to work exactly as before.

Can I change my WiFi password if I do not remember my Xfinity account password?

You will need to sign into your Xfinity account to change your WiFi password through the app or website. If you have forgotten your account password, go to Xfinity.com and click "Forgot username or password?" to reset it. You can also call Xfinity customer service at 1-800-934-6489 for help.

What if I change my password and then forget it?

You can view your current WiFi password at any time by logging into the Xfinity My Account app or website and going to WiFi Settings. You do not need to reset your modem or call support. The password is also printed on the sticker on your modem if you set it back to the default.

Do I need to change my WiFi password regularly?

There is no requirement to change your password on any schedule. However, changing it occasionally is a good security practice, especially if you have shared it with guests or former household members who no longer live with you.

Can I change my WiFi password from a device that is not connected to the network?

Yes. You can change your password using the Xfinity My Account app or website on any device with internet access — it does not have to be connected to your Xfinity WiFi. You can use a phone on cellular data, a computer on a different network, or any other internet-connected device.
