Change Your WiFi Password Through the Xfinity App or Website

You can change your Xfinity WiFi password in about five minutes using either the Xfinity My Account app or the web portal at xfinity.com. The process is the same on both — you log in with your Xfinity account credentials, find your gateway or modem in the device list, and create a new password. The new password takes effect when ready, and all devices will need to reconnect using it.

The fastest route is the mobile app if you have it installed. Open the Xfinity My Account app, tap the menu icon (three horizontal lines), select "Internet," then "Manage WiFi." From there, tap "WiFi Password" and enter your new password twice to confirm it. If you prefer the website, log in at xfinity.com, go to "Internet" in the main menu, select "Manage My WiFi," and follow the same steps.

Your new password must be between 8 and 63 characters long. Xfinity does not restrict what characters you can use — letters, numbers, and symbols all work. Write down your new password somewhere safe before you change it, because you will need to enter it on every device that connects to your WiFi.

Key Takeaways

  • You change your WiFi password through the Xfinity My Account app or website, not by pressing buttons on the modem itself.
  • The new password takes effect right away, and every device on your network will disconnect and need to reconnect using the new password.
  • Your password must be 8 to 63 characters long and can include letters, numbers, and symbols.
  • If you forget your Xfinity account password, you will need to reset it at xfinity.com before you can change your WiFi password.
  • Changing your WiFi password does not affect your internet speed or your Xfinity account — it only controls who can connect to your network.

What Happens When You Change Your WiFi Password

When you save a new password, Xfinity sends it to your gateway or modem within a few seconds. Your WiFi network stays online the whole time, but any device currently connected will lose the connection and see an error message. This is normal and expected.

You will then need to reconnect each device one at a time. On phones and tablets, go to WiFi settings, select your network name, and enter the new password. On computers, do the same through your network settings. Smart home devices, printers, and streaming boxes will also need the new password — if you are not sure how to enter it on a particular device, check the device manual or the manufacturer's website.

The reconnection process usually takes less than a minute per device. If a device refuses to connect even with the correct password, try "forgetting" the network first (in WiFi settings), then reconnecting from scratch.

If You Cannot Log Into Your Xfinity Account

You need your Xfinity account username and password to change your WiFi password through the app or website. If you have forgotten your account password, you will need to reset it before you can proceed.

Go to xfinity.com and click "Sign In" in the top right corner. Then click "Forgot username or password?" and follow the prompts. Xfinity will ask you to verify your identity using your phone number, email address, or account number. Once you have reset your account password, you can log back in and change your WiFi password.

If you do not remember your account number or the phone number on file, call Xfinity customer service at 1-800-934-6489. They can verify your identity and help you reset your account password over the phone.

Changing Your Password on the Modem Itself

Your Xfinity modem or gateway has a small reset button on the back, but pressing it will erase all your settings — including your WiFi password — and return the device to factory defaults. Do not press this button unless you are trying to completely reset your modem, which is a last resort for troubleshooting.

Some older Xfinity modems have a web interface you can access by typing 192.168.0.1 into a browser address bar, but Xfinity no longer recommends this method. The My Account app and website are the official, supported way to change your password, and they are simpler to use.

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 if you think someone has written it down, changing the password will disconnect them. It also prevents neighbors or passersby from using your network without your knowledge.

Another reason is if you have forgotten your current password and need to reconnect a device. Rather than trying to find the original password (which Xfinity does not display in plain text for security reasons), it is faster to set a new one.

You might also change your password if it is too complicated to type on a new device, or if you want to use a password that is easier for family members to remember and enter.

Troubleshooting: Password Change Did Not Work

If you changed your password in the app or website but devices still will not connect, try these steps in order. First, wait 30 seconds after changing the password — sometimes it takes a moment for the modem to update. Then restart the device you are trying to connect (phone, computer, or other gadget) and try again.

If that does not work, go back to the Xfinity My Account app or website and check that your new password was actually saved. Sometimes the page does not refresh properly. Change it again if needed, and make sure you see a confirmation message.

If devices still cannot connect, restart your modem by unplugging it for 30 seconds, then plugging it back in. Wait two to three minutes for it to fully restart, then try connecting again. If the problem continues, contact Xfinity customer service at 1-800-934-6489.

Frequently Asked Questions

Can I change my WiFi password without logging into my Xfinity account?

No. You must log in with your Xfinity account username and password to change your WiFi password through the app or website. This is a security measure to prevent someone else from changing your network settings. If you have forgotten your account password, you will need to reset it first at xfinity.com.

Will changing my WiFi password affect my internet speed?

No. Your internet speed is determined by your Xfinity service plan and the modem itself, not by your WiFi password. Changing the password only controls who can connect to your network — it does not change how fast the connection is.

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

You can change it again by logging into the Xfinity My Account app or website and repeating the same steps. Xfinity does not show you your current password for security reasons, so the only way to recover it is to set a new one.

Do I need to change my WiFi password if I change my Xfinity account password?

No. Your Xfinity account password and your WiFi password are separate. Changing one does not affect the other. You only need to change your WiFi password if you want to control who can connect to your network.

Can I use the same WiFi password on multiple devices?

You have one WiFi network and one password for that network. All devices connect to the same network using the same password. If you want different passwords for different devices, you would need to set up a separate network, which requires a different modem or router.
