Change your WiFi password through the Xfinity app or website

You can change your WiFi password without calling Xfinity or resetting your modem. The fastest way is through the Xfinity My Account app on your phone or the website at xfinity.com. Both let you log in with your Xfinity username and password, then change just the WiFi password in a few steps — your internet stays on the whole time.

The process takes about five minutes. Once you save the new password, it takes effect when ready on your modem. All devices connected to your WiFi will lose connection and need the new password to reconnect.

Key Takeaways

  • You can change your WiFi password through the Xfinity app, the Xfinity website, or by logging into your modem's admin panel directly.
  • Changing your WiFi password is different from changing your Xfinity account password — one affects your internet connection, the other affects your login.
  • After you change the password, every device on your WiFi must reconnect using the new password.
  • If you forget the new password, you can change it again through the same method or reset your modem to factory settings as a last resort.

Change your password through the Xfinity app

Open the Xfinity My Account app on your phone and sign in with your Xfinity username and password. Tap the menu icon (three horizontal lines) in the bottom right corner, then select "Internet" or "Services." Look for an option labeled "WiFi" or "Network Settings" — the exact wording varies depending on your app version.

Tap "WiFi Network Name and Password" or "Change WiFi Password." You will see your current network name (SSID) and password. Tap the password field and enter your new password. Xfinity requires at least 8 characters, and recommends mixing uppercase letters, lowercase letters, numbers, and symbols for security. Tap "Save" or "Confirm." The app will show a confirmation message, and your new password takes effect within seconds.

Change your password through the Xfinity website

Go to xfinity.com and sign in with your Xfinity username and password. Click your account name or profile icon in the top right corner, then select "My Account." Look for "Internet" or "Services" in the left menu, then click "WiFi Settings" or "Network Settings."

You will see your WiFi network name and current password. Click "Edit" or "Change Password" next to the password field. Enter your new password — again, at least 8 characters — and click "Save" or "Update." The change takes effect when ready. If you do not see a WiFi settings option, your account may not have internet service linked to it, or you may need to log out and log back in.

Change your password by logging into your modem directly

If the app or website is not working, you can log into your modem's admin panel. Open a web browser on a device connected to your WiFi and type 192.168.0.1 or 192.168.100.1 into the address bar. You will see a login screen asking for a username and password.

The default username is usually "admin" and the default password is "motorola" or "xfinity" — check the sticker on the back or bottom of your modem if you are not sure. Once logged in, look for "WiFi," "Wireless," or "Network Settings" in the menu. Find the field labeled "WiFi Password," "Pre-Shared Key," or "Passphrase," enter your new password, and click "Save" or "explore." Your modem will restart, and the new password takes effect within a minute.

What to do if devices cannot reconnect after changing the password

"Forgetting" the old WiFi network on each device helps them reconnect cleanly. On phones and tablets, go to WiFi settings, find your Xfinity network name, and select "Forget This Network" or "Remove." Then reconnect by selecting the network again and entering the new password.

On computers, open WiFi settings, find your Xfinity network, and select "Forget" or "Remove." Reconnect the same way. Smart home devices like Alexa speakers or smart TVs may require you to go into their settings app and re-enter the WiFi password. If a device does not have a settings menu, unplug it for 30 seconds, plug it back in, and it will usually prompt you for the new password during startup.

The difference between your WiFi password and your Xfinity account password

Your WiFi password is what you type into your phone or laptop to connect to the internet. Changing it does not affect your Xfinity account login or billing. Your Xfinity account password is what you use to sign into xfinity.com or the Xfinity app to manage your bill and services.

If you change your WiFi password, you can still log into your Xfinity account with your old account password. If you change your Xfinity account password, your WiFi password stays the same and your devices stay connected. The two are separate, so changing one does not change the other.

What to do if you forget your new WiFi password

You can see your current WiFi password by logging back into the Xfinity app, website, or modem admin panel using the same steps above. If you cannot remember your Xfinity account password to log in, go to xfinity.com and click "Forgot Username or Password?" to reset it through your email or phone number.

If you cannot access any of those options, you can reset your modem to factory settings by holding the reset button on the back of the modem for 10 to 15 seconds. This erases your WiFi password and returns it to the default password printed on the modem's sticker. You will then need to set up your WiFi again from scratch using the Xfinity app or website.

Frequently Asked Questions

Will changing my WiFi password disconnect my internet?

No. Your internet connection stays active. Only devices that are connected to your WiFi will disconnect and need to reconnect with the new password. Your modem and the Xfinity network itself are not affected.

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

You can reset your Xfinity account password at xfinity.com by clicking "Forgot Username or Password?" and following the email or phone verification steps. Once you reset it, you can log in and change your WiFi password. Alternatively, you can log into your modem's admin panel directly using the default username and password on the modem's sticker.

How often should I change my WiFi password?

There is no set rule, but changing it once or twice a year is reasonable for most homes. If you suspect someone has accessed your WiFi without permission, change it when ready. If you have guests or contractors who no longer need access, change it to lock them out.

What makes a strong WiFi password?

Use at least 12 characters if possible, mixing uppercase and lowercase letters, numbers, and symbols like ! or #. Avoid dictionary words, birthdays, or names. A random combination like "Tr0pic@lMoon42!" is stronger than "password123" or "MyBirthday1990."

Can I change my WiFi password on my phone if I am not home?

Yes. As long as you have internet access (through cellular data or another WiFi network), you can log into the Xfinity app or website and change your password. The change takes effect on your modem at home when ready, even though you are not there.
