Change your WiFi password through the Xfinity app or website

You can change your Xfinity WiFi network password by logging into your account on the Xfinity website or using the Xfinity My Account mobile app. The process takes about five minutes and does not require you to restart your modem or router. Once you save the new password, all devices currently connected will stay connected — they will not be kicked off automatically.

The new password takes effect when ready for any new devices trying to join your network. Devices already connected will continue working until you manually disconnect them or they lose connection and try to reconnect.

Key Takeaways

  • Log into your Xfinity account on xfinity.com or the Xfinity My Account app to reach the WiFi settings.
  • Your WiFi password is separate from your Xfinity account password — changing one does not change the other.
  • The new WiFi password must be at least 8 characters long and can include letters, numbers, and symbols.
  • Devices already connected to your network will stay connected after you change the password, but new devices will need the new password to join.
  • If you forget the new password, you can view it again in your account settings without changing it a second time.

Steps to change your password on the Xfinity website

Go to xfinity.com and sign in with your Xfinity username and password. Click on the "Internet" or "Services" section, then look for "WiFi" or "Network Settings." The exact wording varies depending on your account type, but it will be grouped with your internet service options.

Find the section labeled "WiFi Network Name" or "WiFi Settings." You should see your current network name (SSID) listed. Next to it or below it, you will see an option to change your WiFi password. Click "Change Password" or "Edit." Enter your new password — it must be at least 8 characters long. You can use uppercase letters, lowercase letters, numbers, and symbols like ! @ # $ % ^ &. Click "Save" or "Confirm."

The system will show a confirmation message. Your new password is now active. You do not need to restart your modem or router.

Steps to change your password in the Xfinity My Account app

Open the Xfinity My Account app on your phone or tablet and sign in. Tap the menu icon (three horizontal lines) in the bottom right corner. Select "Internet" or "Services," then tap "WiFi Settings" or "Network."

Look for your WiFi network name and tap the option to change the password. Enter your new password — remember it must be at least 8 characters. Tap "Save" or "Confirm." The app will show a confirmation, and your new password is active when ready.

What happens to devices already connected to your network

Devices that are currently connected to your WiFi will remain connected after you change the password. They do not automatically disconnect or need to reconnect. This means your phone, laptop, smart TV, and other devices will keep working without interruption.

However, if a connected device loses its WiFi connection — for example, if you restart your router or the device goes out of range and comes back — it will need the new password to reconnect. At that point, you will need to enter the new password on that device.

How to reconnect devices after changing your password

When a device tries to connect to your WiFi after you have changed the password, it will show your network name but will not automatically connect. On the device, go to your WiFi settings and select your Xfinity network name. When prompted for the password, enter your new password exactly as you created it — passwords are case-sensitive, so "MyPassword" is different from "mypassword."

If a device keeps rejecting the password, make sure you are typing it correctly. Common mistakes include forgetting capital letters, mixing up similar-looking characters (like the number 1 and the letter l), or accidentally including a space at the beginning or end. If you are unsure, go back to your Xfinity account and view the password again to double-check.

Difference between your WiFi password and your Xfinity account password

Your WiFi password and your Xfinity account password are two separate things. Your account password is what you use to log into xfinity.com or the Xfinity app. Your WiFi password is what devices use to connect to your home network. Changing one does not change the other.

If you change your Xfinity account password, your WiFi password stays the same and your devices remain connected. If you change your WiFi password, your Xfinity account password is unaffected. This separation means you can update your WiFi security without having to update your login credentials.

Why you might want to change your WiFi password

Change your WiFi password if you think someone outside your household has connected to your network without permission. A crowded network can slow down your internet speed, and unauthorized users can see your browsing activity or access shared files on your devices.

You might also change your password if you recently had a guest or service technician in your home and want to cut off their access. If you have not changed your password since you first set up your internet service, changing it is a good security practice — the default password that came with your router is easier to guess than a custom one you create.

Frequently Asked Questions

Can I see my current WiFi password if I forget it?

Yes. Log into your Xfinity account on xfinity.com or the app, go to WiFi Settings, and you will see your current password displayed. You can view it without changing it. If you need to see it on your computer or phone, you can also check your device's saved WiFi networks — most devices store the password in their settings.

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

No. The new password takes effect when ready without a restart. Your modem and router will continue running normally. Devices already connected will stay connected.

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

You can view your current password anytime by logging into your Xfinity account and checking your WiFi settings. If you want to change it again, follow the same steps. There is no limit to how many times you can change your password.

Will changing my WiFi password affect my internet speed?

No. Your internet speed depends on your service plan and connection quality, not your password. Changing the password does not affect how fast your internet runs.

Can I change my WiFi network name at the same time?

Yes. In your WiFi settings, you will usually see options to change both your network name (SSID) and your password. You can update either one or both together. If you change your network name, devices will see it as a new network and will need to reconnect with the new name and password.
