Change your WiFi password through the Xfinity app or website

You can change your Xfinity WiFi password without calling customer service. The fastest route is the Xfinity My Account app on your phone, which takes about three minutes. If you prefer a computer, log into your account at xfinity.com, go to the Internet section, and find your gateway settings. Both paths let you set a new password when ready — you do not have to wait for a technician or restart your modem.

The password you change here is the one your devices use to connect to your home WiFi network. It is different from your Xfinity account password (the one you use to log into xfinity.com). Changing your WiFi password does not affect your account login, your billing, or your internet speed.

Key Takeaways

  • The Xfinity My Account app is the fastest way to change your WiFi password — it takes about three minutes and the change takes effect when ready.
  • You can also change it on a computer by logging into xfinity.com, selecting Internet, and finding your gateway settings.
  • Your WiFi password is separate from your Xfinity account password and changing one does not affect the other.
  • After you set a new password, your devices will disconnect and you will need to reconnect them using the new password.
  • If you forget your new password, you can reset it the same way you changed it — through the app or website.

Steps to change your password on the Xfinity app

Open the Xfinity My Account app and sign in with your Xfinity username and password. Tap the menu icon (three horizontal lines) in the bottom right corner, then select "Internet." Look for "WiFi Settings" or "Gateway Settings" — the exact wording varies by app version, but it will be in the Internet section.

Tap into WiFi Settings and look for your network name (SSID). You will see a field labeled "WiFi Password" or "Network Password." Tap that field, delete the current password, and type your new one. Xfinity requires at least 8 characters. After you enter it, tap "Save" or "Confirm." The app will show a confirmation message, and your new password takes effect within seconds.

Once the password changes, all your connected devices (phones, laptops, tablets, smart TVs) will disconnect from your WiFi. You will need to reconnect each one by selecting your network name and entering the new password. This usually takes less than a minute per device.

Steps to change your password on a computer

Go to xfinity.com in your web browser and sign in with your Xfinity username and password. Click on "Internet" in the top menu or in the account dashboard. Look for a link or button labeled "Gateway Settings," "WiFi Settings," or "Manage My WiFi" — it is usually near the top of the Internet section.

Click that link and you will see your gateway information. Find the field for your WiFi password (sometimes labeled "Network Password" or "Passphrase"). Click in that field, clear the old password, and type your new one. Remember that Xfinity requires at least 8 characters. Click "Save" or "explore," and the website will confirm the change. Like the app, your new password takes effect within seconds.

After you save, your devices will lose their WiFi connection. Go to each device's WiFi settings, select your network name, and enter the new password to reconnect.

What to do if you cannot find your gateway settings

If you log into xfinity.com and do not see an Internet section or WiFi Settings option, check that you are signed in to the right account. Some accounts are business accounts or have different permission levels that hide these settings. Sign out completely, then sign back in and look again.

If you still cannot find the settings, your account may not have the permissions to change the password online. In that case, you can call Xfinity customer service at 1-800-934-6489 and ask them to change it for you. Have your account number ready. They will set a temporary password and send it to your email, and you can change it again through the app or website once you reconnect.

Why you might want to change your WiFi password

The most common reason is security. If you have shared your WiFi password with someone who no longer lives with you or whom you no longer trust, changing it locks them out. If you suspect someone has been using your WiFi without permission, a new password stops that access when ready.

Another reason is if you have forgotten your current password and cannot find it written down anywhere. Rather than trying to recover the old one, it is faster to set a new one through the app or website. You can also change your password if it is weak or straightforward to guess — Xfinity's default passwords are often straightforward, and setting a longer, more random one makes your network harder to crack.

What happens to your devices after you change the password

Every device connected to your WiFi will disconnect the moment you save your new password. This includes phones, laptops, tablets, smart TVs, smart speakers, security cameras, thermostats, and any other WiFi-connected device in your home. The disconnection is automatic and when ready — you do not have to do anything to trigger it.

After the disconnection, each device will show an error message saying it cannot connect to your network. To reconnect, go to that device's WiFi settings, find your network name in the list of available networks, select it, and enter your new password. Most devices will then stay connected and remember the password for future use. If a device asks for a password every time you turn it on, check that you typed the password correctly — even one wrong character will cause it to fail.

Frequently Asked Questions

Can I change my WiFi password if I do not remember my Xfinity account password?

No, you need to sign into your Xfinity account to change the WiFi password. If you have forgotten your account password, go to xfinity.com and click "Forgot Username or Password?" You will be asked to verify your identity using your phone number, email, or account number. Once you reset your account password, you can then change your WiFi password through the app or website.

How long does it take for the new password to work on all my devices?

The password takes effect on Xfinity's end within seconds of you saving it. However, each device needs time to reconnect individually. Reconnecting usually takes 30 seconds to two minutes per device, depending on how fast your device processes the new password and how busy your network is. Start with the devices you use most often.

What if I change my password and then forget the new one?

You can change it again using the same steps — log into the Xfinity app or xfinity.com, go to WiFi Settings, and set a new password. You do not need to remember the old password to create a new one. If you want to avoid this in the future, write down your new password or store it in a password manager.

Does changing my WiFi password affect my internet speed or service?

No. Changing your WiFi password only changes the security credential that devices use to connect. It does not touch your modem settings, your service plan, or your internet speed. Your connection speed remains the same before and after the password change.

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

Yes. As long as you are signed into your Xfinity account in the app, you can change your WiFi password from anywhere. The change takes effect when ready at your home gateway, even though you are not physically there. This is useful if you want to lock someone out of your network while you are traveling.
