The fastest way to find your Xfinity WiFi password

Your Xfinity WiFi password is stored in your Xfinity account online, and you can retrieve it in about two minutes without calling support. Log into your Xfinity account at xfinity.com, go to the Internet section, find your gateway or modem listed under "My Devices," and select it to view the WiFi name and password. If you do not remember your Xfinity account password, you will need to reset that first before you can see your WiFi password.

The password you see online is the one you set up when your service was installed, or the one Comcast assigned if you never changed it. This is the same password you use to connect phones, laptops, and other devices to your home WiFi network.

Key Takeaways

  • Your WiFi password appears in your Xfinity account under Internet settings, in the device details for your modem or gateway.
  • If you cannot remember your Xfinity account password, use the "Forgot Password" link on xfinity.com to reset it before you can view your WiFi password.
  • The password label on the back or bottom of your physical modem or gateway shows the default WiFi name and password if you have never changed them.
  • If you changed your WiFi password and cannot find it in your account, you can reset your modem to factory settings, which restores the default password printed on the device.

Steps to find your password through your Xfinity account

Start by opening a web browser and going to xfinity.com. Click "Sign In" in the top right corner and enter the email address or username and password for your Xfinity account. If you do not remember your account password, click "Forgot Password" and follow the steps to reset it using your email address or phone number.

Once you are signed in, look for the Internet section or "Services" menu. Click on it and find the device listed under "My Devices" or "Connected Devices" — this will be your modem or gateway, usually labeled with a model number like "xB3" or "xB7." Click on that device to open its details page. Your WiFi network name (SSID) and password will appear on this page, often under a section called "WiFi Details" or "Network Information."

Write down the password exactly as it appears, including capital letters, numbers, and special characters. WiFi passwords are case-sensitive, so "MyPassword123" is different from "mypassword123."

Finding the password on your physical modem or gateway

If you cannot access your Xfinity account or prefer not to, the default WiFi password is printed on a label attached to your modem or gateway. Look on the back or bottom of the device for a white or silver label with information like "WiFi Name" and "WiFi Password" or "SSID" and "Password." The password listed there is what Comcast set when your service was installed.

This method only works if you have never changed your WiFi password since installation. If you changed it at some point, the label will show the old default password, not your current one. In that case, you will need to check your Xfinity account online or reset your modem to restore the default.

What to do if you changed your password and cannot find it

If you changed your WiFi password and did not write it down, you have two options: reset your modem to factory settings, or set a new password through your Xfinity account.

To set a new password through your account, log in at xfinity.com, go to Internet, select your device, and look for an option to "Change WiFi Password" or "Edit Network." Enter a new password and save the changes. This takes effect within a few minutes.

To reset your modem to factory settings instead, locate the small reset button on the back of the device (usually recessed so you need a paperclip or pen to press it). Hold it down for 10 to 15 seconds while the modem is powered on. The modem will restart and return to its default settings, including the WiFi password printed on the label. This will disconnect all your devices, and you will need to reconnect them using the default password. After reconnecting, you can set a new custom password through your Xfinity account if you want.

Resetting your Xfinity account password if you are locked out

If you cannot remember your Xfinity account password and cannot sign in to view your WiFi password, go to xfinity.com and click "Sign In." On the sign-in page, click "Forgot Password" or "Forgot Username." You will be asked to verify your identity using your email address, phone number, or the account number on your Comcast bill.

Comcast will send a password reset link to your email or a code to your phone. Follow the link or enter the code to create a new account password. Once you have reset your account password, sign back in and follow the steps above to find your WiFi password in the Internet section.

Why your password might not appear where you expect

If you log into your Xfinity account and do not see your WiFi password listed, a few things could be happening. Your account may not have Internet service active, or the device may not be registered to your account. Check that you are looking at the correct service address if you have multiple Xfinity accounts.

If your modem or gateway is very old or was purchased from a third party rather than rented from Comcast, it may not appear in your account's device list. In that case, check the label on the device itself for the default password, or contact Comcast support at 1-800-934-6489 to confirm your device is compatible and registered.

Frequently Asked Questions

Can I see my WiFi password on my phone or tablet?

Yes. Open a web browser on your phone, go to xfinity.com, sign in to your account, and navigate to Internet and your device details the same way you would on a computer. The WiFi password will display on your phone screen.

What if I never set up an Xfinity account password?

When Comcast installs your service, they create an account and send you login information by mail or email. If you cannot find that information, go to xfinity.com and click "Forgot Password" to reset it using your email address or phone number associated with the account.

Is it safe to write down my WiFi password?

Writing down your password and keeping it in a safe place at home is fine. Do not share photos of it online or text it to people you do not trust. If you are worried about someone else knowing your password, you can change it anytime through your Xfinity account.

Will resetting my modem delete my internet service?

No. Resetting the modem to factory settings restores the default WiFi password and network settings, but your internet service remains active. You will need to reconnect your devices to WiFi after the reset, and you can set a new custom password through your account afterward.

What if I share my WiFi with roommates and want to change the password?

You can change your WiFi password anytime through your Xfinity account without affecting your internet service. Log in, go to Internet, select your device, and choose the option to change the WiFi password. Let your roommates know the new password so they can reconnect their devices.
