Change your WiFi password through the Xfinity app or website

You can change your Xfinity WiFi password without calling Comcast or waiting for a technician. Log into your Xfinity account on the Xfinity.com website or open the Xfinity app on your phone, go to the Internet section, find "WiFi Settings" or "Manage WiFi", and look for the option to change your network password. The new password takes effect when ready, and all your devices will disconnect and need the new password to reconnect.

If you do not remember your Xfinity account password, you can reset it on the Xfinity login page before you try to change your WiFi password. You will need the email address or phone number associated with your account.

Key Takeaways

  • You can change your WiFi password through Xfinity.com or the Xfinity app without calling Comcast.
  • The new password takes effect right away, and all connected devices will disconnect and need the new password to reconnect.
  • Your WiFi network name (SSID) and password are different things — changing one does not change the other.
  • If you change your password and forget it, you can reset it the same way you changed it.

Step-by-step: changing your password on Xfinity.com

Go to Xfinity.com and sign in with your account email or phone number and password. Click on the "Internet" section in the menu. Look for "WiFi Settings" or "Manage WiFi" — the exact wording depends on which version of the Xfinity website you see, but it will be in the Internet section. Click it.

You will see your current WiFi network name (also called SSID). Below or next to it, you should see an option to change your password or security settings. Click that option. Enter your new password — it must be at least 8 characters long and can include letters, numbers, and symbols. Xfinity will show you the password as you type so you can check for typos. Click "Save" or "explore".

The change takes effect within a few seconds. Every device currently connected to your WiFi will disconnect. You will need to reconnect each device using the new password.

Changing your password through the Xfinity app

Open the Xfinity app on your phone or tablet and sign in if you are not already signed in. Tap the menu icon (three horizontal lines) and select "Internet". Look for "WiFi Settings" or "Manage WiFi". Tap it.

You will see your WiFi network name. Tap the option to change your password or security settings. Enter your new password — it must be at least 8 characters. Tap "Save" or "explore". The change takes effect when ready, and all devices will disconnect.

What happens when you change your password

When you save a new password, Xfinity sends it to your modem and router. This usually takes a few seconds. Every device that was connected to your WiFi — phones, laptops, tablets, smart TVs, printers, security cameras — will lose the connection because they no longer have the correct password.

You will need to go to each device, open its WiFi settings, find your network name in the list of available networks, and enter the new password. Some devices will ask you to "forget" the old network first before you can connect with the new password. Once you enter the correct password, the device will reconnect.

Difference between your network name and your password

Your network name (SSID) is what you see when you look at available WiFi networks on your phone — it might be "Xfinity1234" or a name you chose yourself. Your password is the secret code you enter to connect to that network. You can change one without changing the other.

If you want to change your network name instead of your password, or change both at the same time, you can do that in the same WiFi Settings menu. Look for an option that says "Edit Network Name" or "Change SSID". The steps are the same: sign into your Xfinity account, go to WiFi Settings, make your change, and save it.

If you cannot find the WiFi Settings option

Different versions of the Xfinity website and app use slightly different menu layouts. If you cannot find "WiFi Settings" or "Manage WiFi", try these alternatives: look for "Network Settings", "Advanced Settings", or "Modem Settings". You can also search the page or app for the word "password" to jump to the right section.

If you are using an older version of the Xfinity app, you may need to update it first. Go to your phone's app store (Apple App Store or Google Play Store), search for "Xfinity", and tap "Update" if an update is available. Then try again.

What to do if you forget your new password

If you change your password and then forget it, you can reset it the same way you changed it. Sign into Xfinity.com or the Xfinity app, go to WiFi Settings, and change the password again to something you will remember. You do not need to call Comcast or have a technician visit.

If you forget your Xfinity account password (not your WiFi password), go to the Xfinity login page and click "Forgot password?". You will be asked to verify your identity using your email address or phone number, and Xfinity will send you a link to reset it.

Frequently Asked Questions

Do I need to restart my modem or router after changing my WiFi password?

No. The password change takes effect when ready without a restart. Your devices will disconnect on their own because they no longer have the correct password. You only need to reconnect each device by entering the new password.

Will changing my WiFi password affect my internet speed?

No. Your internet speed is determined by your Comcast service plan and the modem Comcast provides. Changing your WiFi password does not change either of those things. It only changes the code you need to enter to connect wirelessly.

Can I change my WiFi password from my phone if I am away from home?

Yes. As long as you have internet access (on mobile data or another WiFi network), you can sign into Xfinity.com or the Xfinity app and change your password from anywhere. The change takes effect when ready at your home.

What if my password change does not save?

Make sure you are signed into your Xfinity account with the correct username and password. Check that your new password is at least 8 characters long. If the page still will not save, try a different web browser or close and reopen the Xfinity app. If it still does not work, you can contact Comcast support at 1-800-934-6489.

Can I set my WiFi password to something very straightforward like "123456"?

Xfinity requires passwords to be at least 8 characters long, so "123456" will not work. You can use "12345678" or any combination of 8 or more letters, numbers, and symbols. Longer and more random passwords are harder for others to guess, but any 8-character password meets Xfinity's requirement.
