Where your Xfinity WiFi password lives

Your Xfinity WiFi password is printed on a sticker attached to your modem or router — usually on the back or bottom. Look for a label that says "WiFi Password," "Network Key," or "Passphrase." The sticker also shows your network name (SSID), which is what you see when you search for available networks on your phone or computer.

If the sticker is missing, faded, or you cannot find it, you can reset the password through the Xfinity website or the Xfinity app without calling customer service. Both routes take about five minutes.

Key Takeaways

  • Your WiFi password is on a sticker on your modem or router — check the back, bottom, or sides first.
  • You can change your password anytime through the Xfinity website or mobile app using your Xfinity account login.
  • If you do not remember your Xfinity account password, you can reset it on the Comcast login page before you change your WiFi password.
  • Changing your WiFi password will disconnect all devices currently connected — you will need to reconnect them with the new password.
  • If your modem is not responding or you cannot log into your account, contact Xfinity support by phone, chat, or through the Xfinity app.

Changing your password through the Xfinity website

Go to xfinity.comcast.net and sign in with your Xfinity username and password. If you do not remember your password, click "Forgot username or password?" on the login page and follow the steps to reset it — you will need access to the email or phone number on your account.

Once you are logged in, look for "Internet" or "WiFi" in the main menu. Select it, then find the option for "WiFi Settings" or "Manage WiFi." You should see your network name and current password. Click the option to change or reset your WiFi password. Enter a new password (Xfinity usually requires at least 8 characters), confirm it, and save. The change takes effect within a few minutes.

After you change your password, every device connected to your WiFi will be disconnected. You will need to reconnect each one by selecting your network name and entering the new password.

Changing your password through the Xfinity mobile app

Open the Xfinity app on your phone or tablet and sign in with your account credentials. Tap the menu icon (three horizontal lines) and look for "Internet" or "WiFi." Select "WiFi Settings" or "Manage WiFi."

You will see your network name and the option to change your password. Tap it, enter your new password, and confirm. The app will show you when the change is complete. Like the website method, all connected devices will disconnect and need to reconnect with the new password.

What to do if you cannot find your Xfinity account password

If you do not remember the password for your Xfinity account itself (separate from your WiFi password), go to login.xfinity.comcast.net and click "Forgot username or password?" Enter your account number, phone number, or email address associated with your account. Comcast will send a reset link to your email or phone.

Click the link, create a new account password, and then you can log in to change your WiFi password using either method above. This process usually takes a few minutes.

Resetting your modem if the sticker is completely illegible

If the sticker on your modem is too faded to read and you cannot log into your Xfinity account, you can perform a factory reset on the modem itself. This will restore the modem to its original settings, including the default WiFi password printed on a new sticker or shown in the modem's documentation.

To reset your modem, locate the small reset button (usually recessed) on the back or bottom. Use a paperclip or pen to press and hold it for 10 to 15 seconds while the modem is powered on. The lights will blink and the modem will restart. This process takes about five minutes. After the restart, your WiFi network will broadcast with the default password, which you can then change through the Xfinity website or app.

Warning: a factory reset will disconnect all your devices and may temporarily interrupt your internet service. Only do this if you cannot recover your password any other way.

Why you might not be able to log into your account

If you are locked out of your Xfinity account or the website is not accepting your password, your account may have been suspended, or there may be a temporary service issue. Check your email for any messages from Comcast about account problems or billing.

If you see no messages and your account is in good standing, try resetting your Xfinity account password again. If that does not work, contact Xfinity support through the Xfinity app (tap "Support" at the bottom), by phone at 1-800-934-6489, or through the live chat on xfinity.comcast.net. Have your account number or the phone number on your account ready.

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 network, and click "Properties." Scroll down to "Security" and toggle "Show" next to the password field. 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 change my WiFi password and then forget it?

You can change it again anytime through the Xfinity website or app using the same steps. You do not need to remember the old password to set a new one — you only need to log into your Xfinity account.

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

No. Changing your password only affects which devices can connect to your network. Your internet speed and service quality remain the same. The change takes a few minutes to take effect across your network.

Do I need to change my WiFi password regularly?

There is no requirement to change it, but many people change it if they suspect someone unauthorized has the password or if they want to disconnect a device without knowing its password. Changing it once a year is a reasonable practice if security is a concern.

What if my modem does not have a sticker with the default password?

Check the documentation that came with your modem or router — the default password is usually listed there. If you do not have the paperwork, search online for your modem model number plus "default password." If that does not work, log into your Xfinity account and change the password through the website or app, which will override the default.
