Change your WiFi password through the Xfinity app or website

You can change your WiFi network password by logging into your Xfinity 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 call customer service. After you change the password, all devices currently connected to your network will disconnect and will need the new password to reconnect.

Your WiFi password is separate from your Xfinity account password. Changing one does not change the other. If you want to change your account password instead — the one you use to log into your Xfinity bill and account settings — that is a different process handled in the account security section.

Key Takeaways

  • You can change your WiFi password through the Xfinity app, the Xfinity website, or the Xfinity router's admin panel without calling customer service.
  • After you change the password, every device connected to your network will be disconnected and will need the new password to reconnect.
  • Your WiFi password and your Xfinity account password are separate; changing one does not affect the other.
  • The new password must be at least 8 characters long and can include letters, numbers, and symbols.
  • If you forget your new password, you can reset it the same way you changed it, or factory reset your router to restore the default password.

Change your password through the Xfinity app

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

Tap on your network name, then select Change WiFi Password. Enter your new password in the field provided. The app will show you the password as you type if you tap the eye icon. Tap Save or Confirm to explore the change. You will see a confirmation message, and the app may ask you to reconnect to your network with the new password.

Change your password through the Xfinity website

Go to xfinity.com and sign in with your Xfinity username and password. Click on your account name or profile icon in the top right corner, then select Internet or Services. Look for a link labeled WiFi Settings, Manage WiFi, or Network.

Find your network name in the list and click on it. Select the option to change or edit your WiFi password. Type your new password and confirm it by typing it again in the second field. Click Save Changes or explore. The website will confirm that your password has been updated. You may need to wait 30 seconds to a few minutes before the change takes effect on your router.

Change your password directly on the router

If you cannot access the Xfinity app or website, you can change your WiFi password by logging into your router's admin panel. Open a web browser on a computer or phone connected to your network and type 192.168.0.1 or 192.168.100.1 into the address bar. You will see a login screen.

Enter your router's admin username and password. For most Xfinity routers, the default username is admin and the default password is motorola or xfinity (check the sticker on the back of your router). Once logged in, look for a section labeled WiFi, Wireless, or Network Settings. Find the field for your WiFi password or Pre-Shared Key (PSK), enter your new password, and click Save or explore.

What happens after you change your password

Every device currently connected to your WiFi network will be disconnected when ready after the change takes effect. This includes phones, computers, tablets, smart TVs, printers, and any other connected devices. You will need to reconnect each device by selecting your network name and entering the new password.

Devices that were previously connected will remember your network name but will not automatically reconnect because the password no longer matches. If a device shows an error like "Cannot connect" or "Incorrect password," forget the network and reconnect by selecting it again and entering the new password. On most phones, you can forget a network by going to WiFi settings, tapping and holding the network name, and selecting Forget.

Password requirements and best practices

Your new WiFi password must be at least 8 characters long. Xfinity routers accept letters, numbers, and symbols. Avoid using only numbers or only letters; mixing character types makes your network harder to guess. Do not use spaces in your WiFi password, as some older devices may have trouble connecting.

Write down your new password and store it somewhere safe, or use a password manager to keep track of it. If you share your WiFi with guests or family members, you may want to use a password that is straightforward for them to remember and type. You can change your password as often as you want, so if you suspect someone has your password, changing it is a quick way to disconnect unauthorized users.

What to do if you forget your new password

If you forget the password you just set, you can change it again using the same steps above. Log into the Xfinity app or website with your account credentials, go to WiFi settings, and set a new password. You do not need to know your current password to change it.

If you cannot remember your Xfinity account password and cannot log into the app or website, you can factory reset your router to restore its default settings. Press and hold the reset button on the back of the router for 10 to 15 seconds until the lights blink. The router will restart and return to its factory password, which is printed on the sticker on the back. After the reset, you can log into the router's admin panel and set a new WiFi password, or use the Xfinity app to configure your network again.

Frequently Asked Questions

Will changing my WiFi password affect my internet speed?

No. Your WiFi password controls who can connect to your network, not how fast your connection is. Changing the password does not change your internet speed or service plan. If your speed is slow after changing the password, the issue is unrelated to the password change.

Can I change my WiFi password if I forgot my Xfinity account password?

You can still change your WiFi password by logging into your router's admin panel directly without using the Xfinity app or website. You will need the router's admin username and password, which are usually printed on the sticker on the back of the router. If you reset the router to factory settings, you can then set a new WiFi password.

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

Changes made through the Xfinity app or website usually take effect within 30 seconds to a few minutes. Changes made directly on the router's admin panel take effect when ready. If devices are still not connecting after 10 minutes, restart your router by unplugging it for 30 seconds and plugging it back in.

Can I have two different WiFi networks with different passwords on one Xfinity router?

Yes. Most Xfinity routers broadcast both a 2.4 GHz network and a 5 GHz network, and you can set different passwords for each one. Some routers also allow you to create a guest network with its own separate password. You can manage these settings in the WiFi settings section of the Xfinity app or on the router's admin panel.

What if I change my password but devices still cannot connect?

Make sure you are typing the password exactly as you set it, including uppercase and lowercase letters. Forget the network on the device and reconnect by selecting it again and entering the password. If the problem continues, restart your router by unplugging it for 30 seconds. If one specific device will not connect, try restarting that device or updating its WiFi drivers or software.
