The fastest way to find your Xfinity WiFi password

Your Xfinity WiFi password is printed on the sticker attached to your modem or gateway device — look on the back or bottom for a label that says "WiFi Password," "Network Key," or "Security Key." The password is usually an 8 to 12 character mix of letters and numbers. If you cannot find the sticker or it is worn away, you can reset the password through the Xfinity My Account app or website in about two minutes.

The sticker method works when ready and requires no login. If you have already lost or damaged the sticker, resetting through your account is the next fastest option and does not require calling customer service.

Key Takeaways

  • Your WiFi password is printed on a sticker on the back or bottom of your Xfinity modem or gateway device.
  • You can reset your password through the Xfinity My Account app or website without calling customer service.
  • After you change the password, all devices will disconnect and you will need to reconnect them using the new password.
  • If you do not have access to your account, you can reset the modem itself using the physical reset button, which restores the original factory password from the sticker.

Finding the password on the device itself

The easiest place to look is the physical sticker on your modem or gateway. Xfinity attaches a label to the back or bottom of the device that lists the network name (SSID) and the WiFi password. The label may say "WiFi Password," "Network Key," "Security Key," or "Passphrase" — all of these terms mean the same thing.

The password is usually printed in a larger font than other information on the sticker. Write it down exactly as it appears, including capital letters and numbers, because WiFi passwords are case-sensitive. If the sticker is faded or peeling, try wiping it gently with a dry cloth to make the text more readable.

Resetting your password through the Xfinity app or website

If the sticker is missing or unreadable, you can change your WiFi password through your Xfinity account. Open the Xfinity My Account app on your phone or go to xfinity.com and sign in with your account username and password. Once you are logged in, look for "Internet" or "WiFi" in the main menu.

Select "WiFi Settings" or "Manage WiFi," then choose your network name from the list. You will see an option to change the password. Create a new password that is at least 8 characters long and includes a mix of uppercase letters, lowercase letters, and numbers. Write down the new password before you confirm the change, because you will need it to reconnect your devices.

After you save the new password, your modem will restart and all connected devices will disconnect. You will need to reconnect each device (phone, laptop, tablet, smart TV) by selecting the network name and entering the new password. This process usually takes 5 to 10 minutes.

What to do if you cannot access your Xfinity account

If you do not remember your account password or cannot log into Xfinity My Account, you can reset your WiFi password by resetting the modem itself. This restores the device to its factory settings, which means the WiFi password returns to the original one printed on the sticker. You will lose any custom settings you made (like a personalized network name), but your internet connection will work again.

To reset the modem, locate the small reset button on the back or bottom of the device. Use a paperclip or the tip of a pen to press and hold the button for 10 to 15 seconds until the lights on the front of the modem turn off. Wait 2 to 3 minutes for the modem to restart and the lights to come back on. Once the restart is complete, the WiFi password will be the original one from the sticker.

Recovering your Xfinity account password

If you need to change your WiFi password but cannot remember your Xfinity account password, you can reset your account password first. Go to xfinity.com and click "Forgot Username or Password" on the login page. Enter your account phone number or email address, and Xfinity will send you a link to reset your password.

Once you have reset your account password and can log back in, follow the steps in the "Resetting your password through the Xfinity app or website" section above. This route is faster than resetting the modem because you keep your custom network settings.

Why your password might not work after you find it

If you found the password on the sticker but it is not working, the most common reason is that someone has already changed it since the modem was installed. Check whether you are typing it correctly — WiFi passwords are case-sensitive, so "MyPassword123" is different from "mypassword123." Also make sure you are not accidentally including spaces before or after the password.

If you are certain you are typing it correctly, the password has likely been changed. In that case, reset the modem using the physical reset button (which restores the factory password) or reset your account password and change the WiFi password through the Xfinity app.

Changing your password regularly for security

Once you have found or reset your WiFi password, you can change it whenever you want through the Xfinity My Account app or website. There is no limit to how many times you can change it. If you suspect someone has connected to your network without permission, changing the password will disconnect them and prevent them from reconnecting.

When you create a new password, use a combination of uppercase and lowercase letters, numbers, and symbols (like ! or #) to make it harder to guess. Avoid using personal information like your name, address, or birthdate. A strong password is at least 12 characters long, but Xfinity requires a minimum of 8 characters.

Frequently Asked Questions

Where exactly is the WiFi password sticker on my modem?

The sticker is usually on the back of the modem or gateway device, but some models have it on the bottom. Look for a white or gray label with the network name (SSID) and password printed on it. If you cannot find it, check the documentation that came with your modem or contact Xfinity customer service with your account number.

Can I see my WiFi password if I am already connected to the network?

On a Windows computer, go to Settings, then Network & Internet, then WiFi, then Manage Known Networks, select your Xfinity network, and click Properties. Scroll down to find "Security Type" and "Network Security Key" — the key is your password. On a Mac, open Keychain Access, search for your network name, double-click it, check "Show Password," and enter your computer password when prompted.

What happens to my devices when I change my WiFi password?

All devices currently connected to your network will disconnect when ready. You will need to reconnect each device by selecting the network name and entering the new password. Devices that were previously connected will not automatically reconnect — you must enter the new password manually on each one.

Can I reset my WiFi password without resetting the entire modem?

Yes. If you can access your Xfinity account, you can change only the WiFi password through the Xfinity My Account app or website. The modem itself and all your other settings stay the same. You only need to reset the entire modem if you cannot access your account or if you want to restore the original factory password.

How long does it take for the new WiFi password to work after I change it?

The modem usually restarts within 1 to 2 minutes after you save a new password. Wait until all the lights on the front of the modem are back on and stable before you try to reconnect your devices. The entire process from changing the password to having all devices reconnected typically takes 5 to 10 minutes.
