Change your WiFi password through the Xfinity app or website
You can change your Xfinity WiFi password without calling support or resetting your modem. Log into your Xfinity account on the Xfinity My Account app or at xfinity.com, go to the Internet section, select your gateway or modem, and choose "Change WiFi Password." You'll set a new password right there — it takes about two minutes and takes effect when ready on all your devices.
The password you change here is different from your Xfinity account password. Changing your WiFi password does not affect your login to Xfinity.com or your bill. It only changes the network name and password that your phones, laptops, and other devices use to connect to the internet.
Key Takeaways
- You change your WiFi password through the Xfinity My Account app or xfinity.com, not by resetting your modem.
- The new password takes effect when ready, but devices already connected will stay connected until you restart them or manually reconnect.
- If you forget the password after you set it, you can view it again in the same place you changed it — the Internet section of your account.
- Changing your WiFi password does not affect your Xfinity account password, billing, or internet speed.
Step-by-step: using the Xfinity My Account app
Open the Xfinity My Account app on your phone or tablet. Tap the menu icon (three horizontal lines) in the bottom right corner, then tap "Internet." You'll see your gateway or modem listed — tap on it.
Tap "Change WiFi Password." You'll see two fields: one for the network name (SSID) and one for the password. The network name is what shows up when you search for WiFi networks on your phone — you can leave it as is or change it to something you'll recognize. For the password field, enter a new password that is at least 8 characters long and includes a mix of letters, numbers, and symbols (like ! or #). Tap "Save" when you're done.
Your new password is now active. Any device that was already connected will stay connected, but the next time you turn that device off or it goes out of range, you'll need to enter the new password to reconnect.
Step-by-step: using xfinity.com on a computer
Go to xfinity.com and sign in with your Xfinity username and password. Click "Internet" in the top menu, then look for your gateway or modem in the list of devices. Click on it.
Click "Change WiFi Password." You'll see the same two fields as in the app — network name and password. Enter your new password (at least 8 characters, with letters, numbers, and symbols), then click "Save."
The change takes effect within seconds. Devices that are already connected will remain connected until they restart or lose connection. When they reconnect, they'll ask for the new password.
What happens to devices after you change the password
Devices that are currently connected to your WiFi will stay connected even after you change the password. They don't automatically disconnect. However, if a device goes to sleep, restarts, or moves out of range and comes back, it will need the new password to reconnect.
This means you don't have to worry about your laptop suddenly losing internet in the middle of work. But it also means you should tell anyone else in your home about the new password before they try to connect a new device or reconnect an old one. If someone tries to connect and enters the old password, they'll see an error message saying the password is incorrect.
If you forget the password you just set
You can view your current WiFi password at any time by going back to the same place you changed it. In the Xfinity My Account app, go to Internet, select your gateway, and tap "Change WiFi Password" — your current password will be visible there (usually shown as dots or asterisks, but you can tap to reveal it). On xfinity.com, follow the same path and your password will be displayed.
You do not need to contact Xfinity support to recover a forgotten WiFi password. The password is stored in your account and you can view or reset it whenever you log in.
Difference between WiFi password and Xfinity account password
Your WiFi password is what you use to connect devices to your internet network at home. Your Xfinity account password is what you use to log into xfinity.com or the Xfinity app to manage your bill and services. They are completely separate. Changing one does not change the other.
If you want to change your Xfinity account password instead, you can do that by going to xfinity.com, signing in, clicking your profile icon, and selecting "Change Password." That change is separate from your WiFi password and will not affect your internet connection.
Why you might want to change your WiFi password
You might change your WiFi password if you suspect someone outside your home is using your network, if you've shared the old password with someone who no longer lives with you, or if you straightforward want a password that's easier for you to remember. Changing it regularly is a reasonable practice if you're concerned about security.
You do not need to change your WiFi password if you've only changed your Xfinity account password, if you've moved to a new address, or if you're troubleshooting a slow connection — those situations require different steps.
Frequently Asked Questions
Will changing my WiFi password disconnect my devices?
Devices that are currently connected will stay connected. They will only need the new password when they reconnect — either because they restart, go to sleep, or move out of range. You don't have to worry about losing internet in the middle of using your device.
Can I change my WiFi password if I don't remember my Xfinity account password?
No, you need to sign into your Xfinity account to change your WiFi password. If you've forgotten your account password, you can reset it at xfinity.com by clicking "Forgot username or password?" on the sign-in page. You'll verify your identity using your phone number or email, then set a new account password before you can access the WiFi settings.
What if the "Change WiFi Password" option doesn't appear in my account?
This usually means your modem or gateway is not showing up in your account, which can happen if it's not registered or if there's a connection issue. Try signing out and signing back in, or restart your modem by unplugging it for 30 seconds. If the option still doesn't appear, contact Xfinity support — they can check whether your device is properly registered to your account.
Can I change my WiFi password from my phone if I'm not at home?
Yes. As long as you have internet access (on mobile data or another WiFi network), you can sign into your Xfinity account from anywhere and change your WiFi password. The change takes effect when ready, even if you're miles away from your home modem.
Do I need to restart my modem after changing the WiFi password?
No. The password change takes effect when ready without restarting your modem. You only need to restart your modem if you're troubleshooting a connection problem, not for a password change.
