Change your Xfinity WiFi password through the Xfinity My Account app or website

You can change your WiFi password in about five minutes using either your phone or computer. The fastest way is through the Xfinity My Account app if you already have it installed. If you don't have the app, you can log into your account at xfinity.com instead. Both routes take you to the same settings page where you create a new password and push it to your router.

You'll need your Xfinity username and password to log in. If you've forgotten your Xfinity account password (not your WiFi password), you can reset it on the Xfinity login page before you start. Once you change your WiFi password, all your devices will disconnect from the network — you'll need to reconnect them using the new password.

Key Takeaways

  • Log into your Xfinity account through the My Account app or xfinity.com using your Xfinity username and password, not your WiFi password.
  • Navigate to the WiFi settings section and select your network name, then choose the option to change or edit your WiFi password.
  • Your new password must be at least 8 characters long and can include numbers, letters, and symbols.
  • After you save the new password, all devices connected to your WiFi will disconnect and must reconnect using the new credentials.
  • Changes take effect immediately, but it may take a few minutes for your router to broadcast the new network name if you changed that too.

Change your password using the Xfinity My Account app

Open the Xfinity My Account app on your phone or tablet. If you don't have it, download it from the Apple App Store or Google Play Store. Tap the menu icon (three horizontal lines) in the bottom right corner, then tap Internet.

Tap WiFi Settings, then tap the network name you want to change — this is usually "XFINITY" followed by numbers, or a custom name you set up before. Tap Change WiFi Password or Edit (the exact wording depends on your app version). Type your new password in the field that appears. Your password must be at least 8 characters long. Tap Save or Confirm. The app will show a confirmation message when the change is complete.

Change your password using the Xfinity website

Go to xfinity.com and click Sign In in the top right corner. Enter your Xfinity username and password, then click Sign In. You may be asked to verify your identity with a code sent to your phone or email — enter that code if prompted.

Once you're logged in, look for Internet or My Services in the main menu. Click WiFi Settings or Manage WiFi. Find your network name in the list and click Change Password, Edit, or the pencil icon next to it. Type your new password — it must be at least 8 characters. Click Save or Apply. You'll see a confirmation that the change was saved.

What to do after you change your password

Your devices will lose connection to your WiFi network within a few minutes of the change. This is normal. Go to each device's WiFi settings, find your Xfinity network name in the available networks list, and tap or click it. When prompted, enter your new password and select Connect or OK.

Start with devices you use most often — your phone, laptop, or tablet. Smart home devices like security cameras, doorbells, or speakers may take longer to reconnect and may need you to re-enter the password through their own apps. If a device won't reconnect after you've entered the correct password, restart it by unplugging it for 30 seconds, then plugging it back in.

Create a strong password you can remember

Your WiFi password should be different from your Xfinity account password. Use a mix of uppercase letters, lowercase letters, numbers, and symbols (like ! or @) to make it harder to guess. Avoid using your name, address, or birthdate. A good approach is to use a phrase you'll remember — for example, "MyDog!Runs2Fast" — and write it down somewhere safe in case you need it later.

If you share your WiFi with guests or family, you can change your password without affecting your internet service. Your modem and router will keep working normally. Only the WiFi connection requires the new password — devices connected by ethernet cable won't be affected at all.

Troubleshoot if the change doesn't go through

If you see an error message when you try to save your new password, check that it's at least 8 characters long and doesn't contain only numbers or only letters. Some systems require a mix of character types. If the error persists, sign out of your Xfinity account completely, wait 30 seconds, and sign back in. Then try changing the password again.

If the change appears to save but your devices still won't connect with the new password, restart your router by unplugging it for 30 seconds. This forces it to broadcast the updated WiFi settings. If you still can't connect after restarting, log back into your Xfinity account and verify that the password change actually saved — sometimes the page shows a success message even if the change didn't complete.

Frequently Asked Questions

What's the difference between my Xfinity password and my WiFi password?

Your Xfinity password is what you use to log into your account at xfinity.com or the My Account app. Your WiFi password is what you use to connect devices to your home network. They are completely separate. You can change one without affecting the other.

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 exactly the same. The modem itself continues working normally.

Can I change my WiFi password from my router directly instead of through Xfinity?

Yes, you can access your router's settings by typing 192.168.0.1 into a web browser, but using the Xfinity app or website is simpler and recommended. If you change the password through your router's settings page instead, the change may not sync with your Xfinity account, which can cause confusion later.

How often should I change my WiFi password?

There's no set rule, but changing it once or twice a year is reasonable if you want to keep your network secure. Change it immediately if you think someone has your password or if you've shared it with someone who no longer needs access.

What if I forgot my new WiFi password after I changed it?

Log back into your Xfinity account through the app or website, go to WiFi Settings, and look at your network details. Your current password should be visible there. You can change it again if you want to set something easier to remember.
