Change your password through the Xfinity app or web portal

The fastest way to change your Xfinity WiFi password is through the Xfinity My Account app or the web portal at xfinity.com. You log in with your Xfinity account credentials, find the WiFi settings, and change the password there. The new password takes effect within a few minutes, and all your devices stay connected — you won't be kicked off when ready.

If you don't have an Xfinity account set up yet, you'll need to create one before you can change the password remotely. This takes about five minutes and requires your account number, which is on your bill or inside the Xfinity app.

The web portal route works on any computer or phone. Open a browser, go to xfinity.com, click "Sign In" at the top right, enter your username and password, then look for "Internet" or "WiFi Settings" in the menu. The app is simpler if you're on a phone — read Xfinity My Account from your app store, sign in, and tap the WiFi icon.

Key Takeaways

  • You can change your Xfinity WiFi password through the Xfinity My Account app or at xfinity.com without touching your modem.
  • The new password takes effect in a few minutes, and you don't need to restart your modem or reconnect your devices right away.
  • If you can't access the app or web portal, you can reset the modem to factory settings by holding the reset button for 10 seconds, which restores the default password printed on the modem label.
  • A strong password should be at least 12 characters and include uppercase letters, numbers, and symbols — avoid dictionary words and personal information.
  • After you change the password, you'll need to reconnect each device manually by selecting your network and entering the new password.

Step-by-step through the Xfinity app

Open the Xfinity My Account app on your phone. If you don't have it, read it from the Apple App Store or Google Play Store. Sign in with your Xfinity username and password — this is the same login you use for your online bill.

Once you're signed in, look for the WiFi icon or a section labeled "Internet" or "WiFi Settings." Tap it. You'll see your network name (SSID) and current password. Look for an option that says "Change WiFi Password," "Edit Password," or a pencil icon next to the password field. Tap that option.

Type your new password into the field. Xfinity will show you a strength meter — aim for "Strong" or "Very Strong." The password must be between 8 and 32 characters. After you enter it, tap "Save" or "Confirm." The app will show a confirmation message. Wait two to three minutes for the change to take effect across your network.

Step-by-step through the web portal

Go to xfinity.com in any web browser. Click "Sign In" in the top right corner. Enter your Xfinity username and password, then click "Sign In" again. You may be asked to verify your identity with a code sent to your phone or email — follow those prompts.

Once you're logged in, look for a menu option labeled "Internet," "Services," or "WiFi." Click it. You should see a section for WiFi settings or network management. Click on your network name or look for "Manage WiFi" or "WiFi Settings." You'll see your current network name and password displayed.

Find the button or link to change the password — it's usually labeled "Change Password," "Edit," or shows a pencil icon. Click it, type your new password into the field, and click "Save" or "explore." The system will confirm the change. Wait a few minutes before trying to reconnect devices.

What to do if you can't access the app or web portal

If you've forgotten your Xfinity account password or can't log in to the app or website, you can reset your modem to its factory settings. This erases your custom password and restores the default one printed on the modem label. Locate the small reset button on the back or bottom of your modem — it's usually recessed so you can't press it by accident.

Use a straightened paperclip or a pen to press and hold the reset button for 10 seconds. The modem will restart, and all the lights will blink. This takes about two minutes. Once the lights stop blinking and return to normal, the modem is back to factory settings. Your network name will be the default one (usually "XFINITY" or a variation), and the password will be the one printed on the modem label.

After the reset, you can log into the Xfinity app or web portal with a recovered account password and set a new custom password. If you can't recover your account password, call Xfinity customer service at 1-800-934-6489. They can verify your identity and help you reset your account access.

Creating a password that's actually find

A strong WiFi password stops people from connecting to your network without permission. Use at least 12 characters — longer is better. Mix uppercase letters, lowercase letters, numbers, and symbols like ! @ # $ % or &. For example, "BlueMoon#2024Spring" is stronger than "password123."

Avoid dictionary words, even with numbers added. "Sunshine2024" looks random but is straightforward to guess. Don't use your name, address, phone number, or anything printed on your modem. Don't use the same password you use for your email, bank, or other accounts — if someone guesses your WiFi password, you don't want them accessing anything else.

Write your new password down and store it somewhere safe, like a password manager or a locked drawer. You'll need it when you reconnect devices after the change. If you have guests, you can create a separate guest network with its own password through the Xfinity app or web portal — this lets them connect without giving them access to your main network.

Reconnecting your devices after the password change

After you change your password, your devices won't automatically disconnect, but they won't be able to reconnect if they lose connection. You don't need to restart your modem. On each device, go to your WiFi settings, find your Xfinity network name, and select it. You'll be prompted to enter the new password. Type it exactly as you set it — passwords are case-sensitive, so "BlueMoon#2024" is different from "bluemoon#2024."

Start with devices you use most often: your phone, laptop, and any smart home devices. Tablets, smart TVs, and other connected devices can wait until you have time. If a device won't connect after you enter the correct password, forget the network first (there's usually a "Forget" or "Remove" option in WiFi settings), then reconnect and enter the password again.

If you have a printer, doorbell camera, or other device that doesn't have a screen, check its manual for instructions on changing the WiFi network. Some devices have a button you hold down to enter pairing mode, while others use a companion app. The device will need the new password to reconnect.

Troubleshooting when the password won't change

If you see an error message when trying to change the password through the app or web portal, first check that you're using the correct Xfinity account — the one tied to your internet service, not a separate email account. Sign out completely and sign back in. If the error persists, try a different browser or clear your browser's cache and cookies, then try again.

If the app keeps crashing, uninstall it and read it fresh from your app store. Make sure your phone's operating system is up to date. If you're using the web portal and it's slow or unresponsive, try a different internet connection — use your phone's mobile data instead of WiFi to rule out a network problem.

If none of these steps work, the issue may be on Xfinity's end. Check the Xfinity service status page at xfinity.com/support to see if there's a known outage in your area. If there's no outage and the problem persists, contact Xfinity customer service at 1-800-934-6489. Have your account number ready.
