Where to find your Comcast WiFi password

Your Comcast WiFi password is printed on a sticker attached to your modem or gateway device. Look on the back or bottom of the box — the password appears next to "WiFi Password," "Network Key," or "Security Key." The sticker also shows your network name (SSID), which you need to connect.

If the sticker is missing, faded, or you cannot locate your device, you can reset the password through the Xfinity My Account app or website. This is the fastest route when the physical sticker is not readable.

Key Takeaways

  • Your WiFi password is on a sticker on the back or bottom of your Comcast modem or gateway — look for "WiFi Password" or "Network Key."
  • You can change your password anytime through the Xfinity My Account app or at xfinity.com by signing in with your account username and password.
  • If you forget your Xfinity account password, use the "Forgot username or password" link on the Xfinity sign-in page to reset it.
  • A factory reset of your modem will restore the original password on the sticker, but will disconnect all devices and take several minutes to reconnect.

Using the Xfinity My Account app or website

Sign in to your Xfinity account at xfinity.com or open the Xfinity My Account app on your phone. Go to the Internet section and select your gateway or modem. You will see your current WiFi network name and password displayed on the screen.

From this same page, you can change your password to something easier to remember. Click "Change WiFi Password" or "Edit," enter a new password (at least 8 characters, with uppercase, lowercase, numbers, and symbols recommended), and save. The change takes effect when ready, and all connected devices will disconnect and need to reconnect with the new password.

Resetting your Xfinity account password

If you cannot sign in to your Xfinity account, go to xfinity.com and click "Forgot username or password?" on the sign-in page. Enter your phone number, email address, or account number. Comcast will send a reset link to your email or phone.

Click the link and create a new password. Once you have reset your account password, you can sign back in and view or change your WiFi password through My Account. This step is separate from your WiFi password — resetting your account password does not change your WiFi password unless you manually do so.

What to do if you cannot find the sticker

If the sticker on your modem is missing or unreadable, the My Account app is your fastest option. You do not need the sticker to see your password — you only need your Xfinity account login.

If you also do not remember your Xfinity account password, reset it first using the "Forgot username or password?" link, then sign in to My Account to view your WiFi password. This two-step process takes about 10 minutes total.

Performing a factory reset as a last resort

If you cannot access My Account and cannot read the sticker, you can perform a factory reset on your modem. Locate the small reset button (usually recessed) on the back of the device. Use a paperclip or pen to press and hold it for 10 to 15 seconds until the lights on the front blink or turn off.

The modem will restart and restore its original settings, including the default WiFi password printed on the sticker. This process takes 5 to 10 minutes. All devices currently connected will disconnect and will need to reconnect using the original password. You will lose any custom WiFi settings you had configured. Only use this method if you cannot access My Account through any other route.

Connecting devices after you have your password

Once you have your WiFi password, go to your device's WiFi settings. Select your Comcast network name (the SSID from the sticker or from My Account) and enter the password exactly as it appears — passwords are case-sensitive, so uppercase and lowercase letters matter.

If a device will not connect after you enter the correct password, restart the device and try again. If multiple devices fail to connect, restart your modem by unplugging it for 30 seconds, plugging it back in, and waiting for the lights to stabilize (usually 2 to 3 minutes).

Frequently Asked Questions

Can I change my WiFi password without signing into My Account?

No. You must sign in to your Xfinity account through the app or website to change your WiFi password. If you do not remember your account password, reset it first using the "Forgot username or password?" link, then proceed to change your WiFi password.

Is my WiFi password the same as my Xfinity account password?

No. Your WiFi password is what you use to connect devices to your internet. Your Xfinity account password is what you use to sign in to manage your account online. They are separate and can be changed independently.

What if I changed my WiFi password and now cannot remember it?

Sign in to your Xfinity account through My Account and view your current WiFi password on the Internet section. You can also change it to a new password from the same page. There is no way to recover a forgotten password — you can only view or change it through your account.

Does changing my WiFi password disconnect my devices?

Yes. When you change your WiFi password, all connected devices will disconnect when ready. You will need to reconnect each device using the new password. This usually takes a few seconds per device.

What should I do if the factory reset did not work?

Contact Comcast customer service at 1-800-934-6489. They can verify your account, help you reset the modem remotely, or send a technician if the device is not responding. Have your account number ready when you call.
