Change Your WiFi Password Through the Xfinity App or Website

The fastest way to change your Comcast Xfinity WiFi password is through the Xfinity My Account app or website. Log in with your Comcast username and password, go to the Internet section, find your gateway or modem, and look for WiFi settings or Network Name settings. From there you can change the password to anything you want — Comcast will not force you to use their default password.

The app works the same way on iPhone and Android. Open Xfinity My Account, tap Internet, select your gateway, then tap WiFi Password or WiFi Settings. Type your new password and save. The change takes effect when ready, and all your devices will disconnect and need the new password to reconnect.

If you do not have the app, go to xfinity.com, sign in, click Internet, select your gateway, and follow the same steps. You do not need to call Comcast or restart your modem to make the change stick.

Key Takeaways

  • You can change your WiFi password through the Xfinity My Account app or website without calling Comcast or restarting your modem.
  • The new password takes effect when ready, and all connected devices will disconnect and need the new password to rejoin the network.
  • Your WiFi password is separate from your Comcast account password — changing one does not change the other.
  • If you forget your new password, you can reset it to Comcast's default password through the same app or website, then change it again.
  • If the app or website will not let you change the password, restart your modem by unplugging it for 30 seconds, then try again.

What Happens When You Change Your Password

When you save a new WiFi password, your modem broadcasts the change to all devices on your network. Every phone, laptop, tablet, and smart device connected to that WiFi will lose the connection within seconds. You will see a notification that the network is no longer available.

To reconnect, open your WiFi settings on each device, select your Comcast network name (the SSID), and enter the new password. Devices will remember the new password after the first time you enter it, so you will not have to type it again unless you change it once more.

Smart home devices like thermostats, cameras, and speakers may take longer to reconnect or may need you to remove and re-add them in their own apps. Check the device manual if it does not reconnect automatically after a few minutes.

Reset to the Default Password If You Forget Your New One

If you change your password and then forget it, you can reset it back to Comcast's default password through the Xfinity app or website. Go to Internet, select your gateway, find WiFi settings, and look for a Reset or Restore Default option. This will set your password back to the one printed on the back or bottom of your modem.

Once you reset to the default, you can change it again to something you will remember. Write down your new password somewhere safe, or use a password manager to store it.

Troubleshoot If the App or Website Will Not Let You Change It

If you log in but the password change option is grayed out or does not save, restart your modem. Unplug the power cable from the back of the modem, wait 30 seconds, and plug it back in. Wait two to three minutes for the modem to fully restart, then try changing the password again through the app or website.

If the option is still not available, make sure you are logged into the Xfinity My Account app or website with the correct Comcast username and password. If you are not the account holder, you may not have permission to change WiFi settings — the account owner will need to make the change or give you permission in the app.

If you still cannot change the password after restarting the modem and confirming you are logged in as the account owner, contact Comcast support at 1-800-934-6489 or through the Xfinity app's chat feature.

Change Your Password Regularly for Security

Changing your WiFi password every few months makes it harder for someone outside your home to guess or crack it. A strong password is at least 12 characters long and includes uppercase letters, lowercase letters, numbers, and symbols — something like BlueSky#2024Home instead of password123.

Avoid using your name, address, phone number, or anything else someone could learn about you from social media. Do not use the same password as your Comcast account or any other account you use online.

Difference Between WiFi Password and Comcast Account Password

Your WiFi password is what guests and devices use to connect to your internet. Your Comcast account password is what you use to log into Xfinity My Account to pay your bill and manage your services. They are completely separate, and changing one does not change the other.

If you forget your Comcast account password, you can reset it on the Xfinity login page by clicking Forgot Username or Password. If you forget your WiFi password, you can reset it to the default through the Xfinity app or website as described above.

Frequently Asked Questions

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

No. The password change takes effect when ready without a restart. Your devices will disconnect and need the new password to reconnect, but the modem itself does not need to be restarted. Only restart if the app or website will not let you change the password in the first place.

Can I change my WiFi password on the modem itself without using the app?

Yes, but it is more complicated. You can log into your modem's admin page by typing 192.168.0.1 or 192.168.100.1 into a web browser, then entering the admin username and password (usually admin and motorola, or check the modem's label). From there you can change the WiFi password, but the app is faster and easier for most people.

What if I have two WiFi networks showing up — one with 5G in the name?

Comcast modems broadcast both a 2.4 GHz network and a 5 GHz network with similar names. You can change the password for both at once through the app, or change them separately if you want different passwords. Most devices will automatically pick the faster 5 GHz network if they are close to the modem.

Will changing my WiFi password disconnect my smart TV or security camera?

Yes, all devices will disconnect. Smart TVs and cameras will need you to enter the new password in their WiFi settings or in their apps before they reconnect. Check the device manual if you are not sure how to re-enter the password.

Can someone outside my house change my WiFi password?

No, they would need to log into your Xfinity My Account with your Comcast username and password. Protect your Comcast account password the same way you protect your email or banking passwords, and use a strong password that is not straightforward to guess.
