Change your WiFi password through the Xfinity app or website

You can change your Xfinity WiFi password by logging into your Xfinity account on the web or through the Xfinity My Account app. The process takes about five minutes and doesn't require you to restart your router or call customer support. You'll need your Xfinity username and password to start.

The password you change here is the one your devices use to connect to your home WiFi network — not your Xfinity account password itself. Changing it regularly is a good security practice, especially if you've shared it with guests or if you suspect someone has been using your network without permission.

Key Takeaways

  • Log into your Xfinity account at xfinity.com or through the Xfinity My Account app to reach the WiFi settings.
  • Your WiFi password is separate from your Xfinity account password, and changing one does not affect the other.
  • After you change your password, all your devices will disconnect and you'll need to reconnect them using the new password.
  • If you forget the new password you just set, you can view it again in the same Xfinity account settings where you changed it.
  • Changing your WiFi password does not require a technician visit or a router restart.

Steps to change your password on the Xfinity website

Go to xfinity.com and sign in with your Xfinity username and password. Once you're logged in, look for "Internet" or "WiFi" in the main menu — the exact wording varies depending on your account type, but it's usually near the top of the page.

Click on that section, then look for a link that says "WiFi Settings," "Manage WiFi," or "WiFi Password." Select it. You should see your current network name (SSID) and a field to enter a new password. Type your new password — Xfinity requires at least 8 characters, and it's stronger if you mix uppercase letters, lowercase letters, numbers, and symbols. Click "Save" or "Update" when you're done.

The change takes effect when ready. Every device currently connected to your WiFi will disconnect within a few seconds. You'll need to reconnect each one by selecting your network name and entering the new password.

Steps to change your password in the Xfinity My Account app

Open the Xfinity My Account app on your phone or tablet and sign in. Tap the menu icon (usually three horizontal lines) in the top left or bottom right, depending on your device. Look for "Internet," "WiFi," or "Services" in the menu.

Tap on that section, then find "WiFi Settings" or "Manage WiFi." You'll see your network name and a button to change your password. Tap it, enter your new password (8 characters minimum), and confirm. The app will show you a confirmation message when the change is saved.

Just as with the website, your devices will disconnect and need to reconnect with the new password. This usually happens within 30 seconds to a minute.

What happens to your devices after you change the password

When you save a new WiFi password, Xfinity sends the update to your router. Your router then broadcasts the change to all connected devices. Phones, laptops, tablets, smart TVs, and any other WiFi-connected devices will lose their connection and show an error message saying the password is incorrect or the network is unavailable.

You don't need to do anything to your router itself — no unplugging, no reset button. Just go to each device, select your network name, and enter the new password. Most devices will remember the new password after you enter it once, so you won't have to type it again the next time you connect.

If you have a device that you can't easily access (like a smart home device mounted on a wall or a printer in another room), you can reconnect it later. There's no time limit — the device will keep trying to connect with the old password until you update it.

If you forget the password you just set

You can view your current WiFi password anytime by going back into your Xfinity account settings through the website or app. Follow the same steps you used to change it, and instead of entering a new password, look for an option to "View Password" or "Show Password." Xfinity will display your current WiFi password on the screen.

You don't need to call support or reset anything to retrieve it. If you want to change it again because you're concerned about security, you can do that when ready.

Security reasons to change your WiFi password

Your WiFi password is the main barrier between your home network and anyone nearby who wants to connect to it. If you've given the password to guests, contractors, or family members who no longer live with you, changing it is a straightforward way to remove their access. You won't hurt their feelings or create awkwardness — they straightforward won't be able to reconnect.

If you suspect someone is using your WiFi without permission, a password change will disconnect them when ready. You can also check which devices are currently connected to your network through the Xfinity app — look for a "Connected Devices" or "WiFi Devices" section — to see if anything looks unfamiliar.

Changing your password every few months is a reasonable practice if you live in a dense apartment building or a neighborhood where many people live close together. It doesn't prevent sophisticated attacks, but it does prevent casual unauthorized use.

Frequently Asked Questions

Will changing my WiFi password affect my Xfinity account password?

No. Your WiFi password and your Xfinity account password are completely separate. Changing one has no effect on the other. Your account password is what you use to log into xfinity.com or the app. Your WiFi password is what your devices use to connect to your home network.

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

No. The change takes effect automatically on your router. You don't need to unplug it, press any buttons, or do anything physical to the device. Just change the password in your account settings and reconnect your devices.

What if I can't log into my Xfinity account to change the password?

If you've forgotten your Xfinity account password, you can reset it at xfinity.com by clicking "Forgot Username or Password" on the login page. If you're having trouble logging in for another reason, Xfinity customer support can help you regain access to your account.

Can I change my WiFi password from my phone if I'm away from home?

Yes. As long as you have internet access on your phone (through cellular data or another WiFi network), you can log into your Xfinity account and change your home WiFi password from anywhere. The change will take effect on your home router when ready, even though you're not there.

How strong should my new WiFi password be?

Xfinity requires at least 8 characters. A stronger password includes a mix of uppercase letters, lowercase letters, numbers, and symbols — for example, "BlueSky#2024Home" is stronger than "password123." Avoid using your name, address, or birthdate. You don't need to memorize it; you can view it anytime in your Xfinity account settings.
