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

You can change your Xfinity WiFi password without calling support or resetting your modem. Log into your Xfinity account on the web at xfinity.com or through the My Account mobile app, go to the Internet section, find "WiFi," and select "Edit WiFi Name and Password." You'll see your current network name (SSID) and can create a new password right there. The change takes effect within a few minutes, and all your devices will need the new password to reconnect.

If you don't remember your Xfinity account password, you can reset it on the Xfinity sign-in page before you start. You'll need your account number or the phone number associated with your account, plus access to the email on file.

Key Takeaways

  • The easiest way is through My Account on xfinity.com or the mobile app — no phone call needed.
  • Your new password takes effect in a few minutes, and every device connected to your WiFi will need to enter it again.
  • You can change your network name (SSID) at the same time if you want to rename your WiFi.
  • If you forget your new password later, you can always view it again in the same WiFi settings section.

Step-by-step: using the Xfinity website

Go to xfinity.com and sign in with your account username and password. If you're not sure which email or username you use, the sign-in page has a "Trouble signing in?" link that will walk you through recovery.

Once you're logged in, look for the Internet section in the main menu. Click on "Internet" or "Services," then find the WiFi option. You should see a card or section labeled "WiFi" with your current network name displayed. Click "Edit WiFi Name and Password" or a similar button — the exact wording changes occasionally, but it will be near your network name.

A box will pop up showing your current network name and password. Change the password field to something new. Xfinity requires at least 8 characters, and it's stronger if you mix uppercase, lowercase, numbers, and symbols. You can also change your network name if you want — this is the name people see when they search for WiFi networks. Click "Save" when you're done.

Step-by-step: using the My Account mobile app

Open the My Account app on your phone and sign in. Tap the menu icon (usually three horizontal lines) and look for "Internet" or "Services." Select it, then tap "WiFi."

You'll see your current network name and an option to edit it. Tap "Edit WiFi Name and Password" or "Manage WiFi." Enter your new password in the password field — remember, at least 8 characters. You can also change your network name here if you want. Tap "Save" or "Done" to confirm.

What happens after you change your password

Your modem will explore the new password within a few minutes. During that time, your internet connection should stay on, but you won't be able to connect any new devices until the change is complete. Devices already connected will stay connected until they disconnect or lose signal.

After the change takes effect, every device that was using your old password will lose connection to the WiFi. You'll see a notification on your phone or computer saying the network password is incorrect. Go into your WiFi settings, select your Xfinity network, and enter the new password. Do this for every device you use — phones, tablets, laptops, smart TVs, printers, and anything else on your network.

If you can't access your Xfinity account online

If you've forgotten your Xfinity account password, reset it before you try to change your WiFi password. Go to xfinity.com, click "Sign In," then click "Trouble signing in?" You can reset your password using your account number, phone number, or the email on file. You'll receive a reset link by email or text.

If you don't have access to the email or phone number on your account, or if you're having trouble with the online reset, you can call Xfinity customer service at 1-800-934-6489. They can verify your identity and reset your account password over the phone, which takes about 10 minutes.

Why you might want to change your WiFi password

Change your password if you suspect someone has it but shouldn't — a houseguest who left, a neighbor, or anyone else. A strong password that only you and people living in your home know makes it harder for others to use your internet without permission. This protects both your bandwidth and your privacy, since anyone on your network can potentially see what devices are connected and what traffic is moving across it.

You might also change your password if you want to rename your network to something more recognizable to you, or if you're setting up a guest network and want a separate password for visitors.

Frequently Asked Questions

Will changing my WiFi password disconnect my internet?

No. Your internet connection stays on during the change. Devices already connected to WiFi will stay connected until they disconnect or the signal drops. Only new devices trying to connect will need the new password.

Can I change my WiFi password from my phone if I'm not home?

Yes. As long as you have internet access (cellular data or another WiFi network), you can log into your Xfinity account and change your password from anywhere. The change will take effect on your modem at home within a few minutes.

What if I change my password and then forget it?

Log back into your Xfinity account on xfinity.com or the My Account app and go to the WiFi settings. Your current password is displayed there, so you can see it or write it down. You can also change it again if you want something easier to remember.

Do I need to restart my modem after changing the password?

No. The password change takes effect automatically within a few minutes. You don't need to unplug your modem or restart anything. If a device isn't connecting after 10 minutes, try restarting that device instead.

Can I have different passwords for different devices?

No. All devices connecting to your main Xfinity WiFi network use the same password. If you want a separate password for guests, Xfinity lets you set up a guest network with its own name and password through the same WiFi settings page.
