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" or "Network Key." The password is usually an 8 to 12 character combination 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, or by calling Xfinity customer service at 1-800-934-6489.

The sticker method works when ready and requires no login. If you have lost or damaged the sticker, resetting through your account takes about five minutes and gives you a password you choose yourself.

Key Takeaways

  • The WiFi password is printed on a sticker on the back or bottom of your Xfinity modem or gateway.
  • You can reset your WiFi password through the Xfinity My Account app or website if you know your account username and password.
  • Xfinity customer service can help you reset the password over the phone if you cannot access your account online.
  • After you change your password, all devices will disconnect and you will need to reconnect using the new password.

Finding the password on your modem or gateway

Every Xfinity modem and gateway ships with a WiFi password printed on a label. This label is usually on the back of the device, but on some models it is on the bottom or side. The label shows your network name (SSID) and the password next to it.

The password may be labeled as "WiFi Password," "Network Key," "Passphrase," or "Security Key" depending on your device model. Write down the exact password as it appears — it is case-sensitive, meaning uppercase and lowercase letters matter. If the sticker is faded or missing, move to the next method.

Resetting your password through the Xfinity My Account app

Open the Xfinity My Account app on your phone or tablet and sign in with your Xfinity username and password. Tap the menu icon (three horizontal lines) and select "Internet." Then tap "WiFi" and choose "Change WiFi Password."

You will see your current network name and a field to enter a new password. Xfinity requires passwords to be at least 8 characters long and recommends mixing uppercase letters, lowercase letters, numbers, and symbols. After you enter your new password and confirm it, tap "Save." The change takes effect when ready, and all connected devices will disconnect.

Resetting your password on the Xfinity website

Go to xfinity.com and sign in with your username and password. Click on your account name in the top right corner and select "Internet." Look for the "WiFi" section and click "Change WiFi Password."

Enter your new password in the field provided. Make sure it is at least 8 characters and includes a mix of character types if possible. Click "Save Changes" when you are done. Your new password will be active within a few seconds, and you will need to reconnect all your devices.

Calling Xfinity customer service to reset your password

If you do not have access to the My Account app or website, or if you forget your Xfinity account password, call Xfinity customer service at 1-800-934-6489. A representative can reset your WiFi password over the phone and either tell you the new password or help you set one yourself.

Have your account number or the phone number associated with your account ready when you call. The representative will verify your identity before making any changes. This method works even if you cannot access your modem or the online account portal.

What to do if you cannot connect after resetting

After you change your WiFi password, your phone, laptop, tablet, and other devices will no longer be connected to the network. You will need to "forget" the old network on each device and reconnect using the new password.

On most phones and computers, go to your WiFi settings, find your Xfinity network name, and select "Forget" or "Remove." Then search for the network again, select it, and enter your new password. If a device still will not connect, restart the modem by unplugging it for 30 seconds and plugging it back in, then try connecting again.

Frequently Asked Questions

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

On Windows, go to Settings > Network & Internet > WiFi > Manage Known Networks, select your Xfinity network, and click "Properties." Scroll down to "Security" and toggle "Show" to reveal the password. On Mac, open Keychain Access, search for your network name, double-click it, check "Show password," and enter your computer password when prompted.

What if I lost the sticker and do not remember my Xfinity account password?

Call Xfinity customer service at 1-800-934-6489 and explain that you need to reset your WiFi password. The representative can verify your identity using your account number, phone number, or other information and reset the password without needing your account login.

Do I have to use the password on the sticker, or can I change it?

You can change your WiFi password anytime through the My Account app, website, or by calling customer service. Many people change it to something easier to remember. Just make sure it is at least 8 characters long.

Will changing my WiFi password affect my internet speed or service?

No. Changing your WiFi password only affects which devices can connect to your network. Your internet speed and service remain the same. You may need to restart your modem if devices have trouble reconnecting after the change.
