Change your WiFi password through the Xfinity app or website

You can change the password your devices use to connect to your Xfinity WiFi network by logging into your Xfinity account online or through the Xfinity app on your phone. The process takes about five minutes and does not require you to restart your modem. Once you change it, all your devices will need the new password the next time they try to connect.

This is different from changing your Xfinity account password (the one you use to log into your bill and account settings). Your WiFi password is what guests and your own devices type in to join your home network. You can change it as often as you want without affecting your internet service.

Key Takeaways

  • Log into your Xfinity account at xfinity.com or open the Xfinity app, then navigate to the WiFi settings section to change your network password.
  • Your new password takes effect when ready, but devices already connected will stay online until they disconnect or you restart them.
  • Write down or save your new password somewhere safe before you change it, because you will need to give it to anyone who wants to join your network.
  • If you forget your new password after changing it, you can log back into your account and view it again at any 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 profile icon or menu in the top right corner and select "Internet" or "Services." Look for a section labeled "WiFi" or "Network Settings" — the exact wording varies depending on your account type.

Find your network name (also called your SSID) in the list of networks. Next to it, you should see an option to edit or manage the network. Click that option, then look for a field that says "WiFi Password" or "Network Password." Delete the old password and type in your new one. Passwords are case-sensitive, so uppercase and lowercase letters matter. Click "Save" or "explore" when you are done.

The website will confirm that your password has been changed. You do not need to do anything else — your modem will not restart, and your internet will keep running. Devices that are already connected will stay connected until you restart them or they lose their connection.

Steps to change your password in the Xfinity app

Open the Xfinity app on your phone and sign in if you are not already logged in. Tap the menu icon (usually three horizontal lines) at the bottom or top of the screen. Select "Internet" or "Services," then tap "WiFi Settings" or "Manage WiFi."

You should see your network name listed. Tap on it or on an edit button next to it. Find the field labeled "WiFi Password" or "Network Password" and tap it to edit. Clear the old password and enter your new one. Remember that passwords are case-sensitive. Tap "Save" or "Done" when you finish.

The app will show a confirmation message. Like the website method, this change takes effect right away without restarting your modem or interrupting your service.

What happens to devices after you change your password

Devices that are currently connected to your WiFi will stay connected for a while after you change the password. They do not automatically disconnect. However, if a device loses its connection — because it goes to sleep, moves out of range, or you restart it — it will need your new password to reconnect.

If you have guests or family members on your network, tell them the new password before they try to reconnect. They will see an error message saying the password is incorrect if they try to use the old one. You can give them the new password over text, email, or by writing it down.

How to find your password if you forget it after changing it

Log back into your Xfinity account at xfinity.com or open the Xfinity app. Go to the same WiFi settings section where you changed the password. Your current password will be displayed there (usually with dots or asterisks hiding it, but you can often click an eye icon to reveal it). Write it down or take a screenshot so you have it handy.

If you have trouble finding the password in your account, you can also look for it on a sticker attached to your modem or router. However, if you changed the password through your account, the sticker will show your old password, not your new one. Always check your account settings for the most current password.

Choosing a strong WiFi password

When you create a new password, use a mix of uppercase letters, lowercase letters, numbers, and symbols (like ! or @). Avoid using words that appear in the dictionary or personal information like your name or address. A password that is at least 12 characters long is harder for someone to guess.

You do not need to change your WiFi password regularly unless you suspect someone has gained access to your network or you want to remove someone's access. If you notice unfamiliar devices connected to your WiFi or your internet speed has dropped suddenly, changing your password is a good first step to find your network.

Troubleshooting if the change does not work

If you see an error message when you try to save your new password, check that you are using allowed characters. Xfinity WiFi passwords typically accept letters, numbers, and common symbols, but some special characters may not be allowed. Try removing any unusual symbols and use only standard keyboard characters.

If the website or app does not let you access the WiFi settings at all, make sure you are signed into the correct Xfinity account — the one associated with your internet service. If you have multiple Xfinity accounts, you may be logged into the wrong one. Sign out completely and sign back in with the account that pays for your internet.

If you still cannot change your password after trying these steps, contact Xfinity customer service by phone or through the app's chat feature. They can verify your account and help you change the password manually.

Frequently Asked Questions

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

No. Your modem does not need to restart. The password change takes effect when ready in your account. Devices that are already connected will stay online, but any device that disconnects will need the new password to rejoin.

Will changing my WiFi password affect my internet speed?

No. Your internet speed depends on your service plan and connection to the modem, not on your WiFi password. Changing the password does not change how fast your internet runs.

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

Yes. As long as you have the Xfinity app installed or can access xfinity.com through your phone's browser, you can change your password from anywhere. You do not need to be connected to your home WiFi to make this change.

What if I change my password and then forget it before anyone writes it down?

Log back into your Xfinity account and view your WiFi settings again. Your current password will be displayed there. You can view it as many times as you need until everyone has written it down or saved it.

Can I set my WiFi password to be the same as my Xfinity account password?

Technically yes, but it is not recommended. Your WiFi password is shared with guests and family members, while your account password should stay private. Keep them different so that if someone learns your WiFi password, they cannot access your account or billing information.
