Change your WiFi password through the Xfinity app or website

You can change your WiFi password by logging into your Xfinity account on the Xfinity website or mobile app, then navigating to the WiFi settings section. The process takes about five minutes and does not require calling Xfinity or restarting your router. Once you save the new password, it takes effect when ready on new devices trying to connect — devices already connected stay online until you restart them or they reconnect.

You will need your Xfinity username and password to log in. If you do not remember your Xfinity account password, you can reset it on the login page before you start. Your WiFi password is separate from your Xfinity account password, so changing one does not affect the other.

Key Takeaways

  • Log into your Xfinity account at xfinity.com or through the Xfinity app, then go to Internet settings to find your WiFi password options.
  • Your new WiFi password takes effect when ready, but devices already connected will stay online until you manually disconnect them or they reconnect.
  • WiFi passwords must be at least 8 characters long and can include letters, numbers, and symbols — avoid spaces and special characters that are hard to type on phones.
  • If you forget your new password, you can view it again in the same Xfinity settings menu without changing it again.
  • Changing your WiFi password does not affect your internet speed, billing, or Xfinity account settings.

Step-by-step: changing your password on the Xfinity website

Go to xfinity.com and click "Sign In" at the top right. Enter your Xfinity username (usually your email address) and your account password. Once you are logged in, look for "Internet" or "My Services" in the top menu and click it.

Find the section labeled "WiFi" or "WiFi Settings" — this is usually under "Internet" or "Manage My Services." Click on it. You should see your current network name (SSID) and an option to change your WiFi password. Click the button that says "Change WiFi Password" or "Edit WiFi Settings." Enter your new password in the field provided, then click "Save" or "explore." The system will confirm the change within a few seconds.

Write down your new password or save it in a password manager before you close the page. You will need it to connect new devices to your WiFi.

Step-by-step: changing your password in the Xfinity app

Open the Xfinity app on your phone or tablet and tap "Sign In" if you are not already logged in. Enter your Xfinity username and password. Once you are in, look for "Internet" at the bottom of the screen or in the main menu.

Tap "Internet" and then look for "WiFi Settings" or "Manage WiFi." You should see your network name and a button to change your password. Tap "Change WiFi Password" and enter your new password in the field. Tap "Save" or "explore" to confirm. The app will show a confirmation message when the change is complete.

What happens to devices already connected to your WiFi

Devices that are already connected to your WiFi will stay connected after you change the password — they do not need the new password to keep working. However, if a device disconnects (loses power, goes out of range, or gets restarted), it will need the new password to reconnect.

If you want to force all devices to disconnect when ready and require the new password, you can restart your Xfinity router by unplugging it for 30 seconds and plugging it back in. This is not necessary unless you are concerned about an unauthorized device on your network.

Choosing a strong WiFi password

Your WiFi password must be at least 8 characters long. You can use uppercase letters, lowercase letters, numbers, and symbols like ! @ # $ % ^ & * ( ). Avoid spaces and characters that are hard to type on a phone keyboard, such as backslash or forward slash.

A good WiFi password is something you can remember but that is not straightforward to guess — avoid birthdays, addresses, or common words. A mix of uppercase and lowercase letters with a few numbers works well. For example, "BlueSky2024!" is stronger than "password123" or "12345678."

Troubleshooting: password change did not work

If you see an error message when you try to save your new password, check that it is at least 8 characters long and does not contain spaces. If the error persists, try logging out of your Xfinity account completely and logging back in, then try again.

If the website or app is not loading the WiFi settings section, try using a different web browser or clearing your browser cache. If you are using the app, try closing it completely and reopening it. If none of these steps work, you can call Xfinity customer service at 1-800-934-6489 and ask them to change your WiFi password for you over the phone.

Finding your WiFi password if you forgot it

You can view your current WiFi password in the same Xfinity settings menu where you changed it. Log into your Xfinity account, go to Internet settings, and look for "WiFi Settings" or "WiFi Password." The password is usually hidden behind a "Show" button or eye icon — click it to reveal the password in plain text.

If you cannot access your Xfinity account, you can also find your WiFi password on the back or bottom of your Xfinity router — it is usually printed on a sticker labeled "WiFi Password" or "Network Key." This is the password that came with your router when it was installed, not any password you changed later.

Frequently Asked Questions

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

No, you do not need to restart your router. The new password takes effect when ready. You only need to restart your router if you want to force all connected devices to disconnect and require the new password to reconnect.

Will changing my WiFi password affect my internet speed?

No. Your WiFi password controls who can connect to your network, but it does not affect how fast your internet is. Your speed depends on your Xfinity plan and your router's distance from your devices.

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

Yes. As long as you have the Xfinity app installed and you know your Xfinity account password, you can change your WiFi password from anywhere. You do not need to be connected to your WiFi network to make the change.

What if I change my WiFi password and then forget it when ready?

Log back into your Xfinity account and go to the same WiFi settings menu. Your new password will be displayed there (usually behind a "Show" button). You can view it as many times as you need without changing it again.

Can I have two different WiFi passwords for 2.4 GHz and 5 GHz?

Most Xfinity routers use the same password for both bands by default. Some newer routers allow you to set separate passwords in the advanced WiFi settings, but this is not common. Check your router's settings in the Xfinity app or website to see if this option is available for your model.
