Change your WiFi password through the Xfinity app or web portal
You can change your Xfinity WiFi password in two ways: through the Xfinity app on your phone or through the web portal on any browser. Both routes take about five minutes and require your Xfinity username and password to log in. The app is faster if you have it installed; the web portal works if you do not.
The password you change is the one people use to connect to your home WiFi network — not your Xfinity account password. Changing your WiFi password does not affect your internet service or billing. Anyone already connected to your network will stay connected until they disconnect and try to rejoin; then they will need the new password.
Key Takeaways
- You can change your WiFi password through the Xfinity app or at xfinity.com by logging into your account.
- The new password takes effect when ready, but people already connected to your network can stay online until they disconnect.
- Your WiFi password must be at least 8 characters long and can include letters, numbers, and symbols.
- If you forget the new password, you can view it again in the same place you set it without resetting your modem.
- Resetting your modem to factory settings will erase your custom WiFi password and restore the default one printed on the device.
Change your password using the Xfinity app
Open the Xfinity app and tap the menu icon (three horizontal lines) in the bottom right corner. Select "Internet" and then "WiFi Settings." You will see your current network name and a button to change the password. Tap it and enter your new password — it must be at least 8 characters long.
The app will confirm the change and show your new password on screen. Write it down or take a screenshot before you leave this screen, because you will need it to reconnect any devices. The change takes effect within a few seconds.
Change your password through the Xfinity web portal
Go to xfinity.com and log in with your Xfinity username and password. Click "Internet" in the top menu, then select "WiFi Settings" or "Manage My WiFi." You will see your network name and a link to change the password. Click it and type your new password into the field.
The portal will ask you to confirm the new password by typing it again. Click "Save" and the change will take effect within seconds. You can close the browser and the new password is active — you do not need to restart your modem or do anything else.
What to do if you cannot log into Xfinity online
If you have forgotten your Xfinity account password, you will need to reset it before you can change your WiFi password through either method. Go to xfinity.com and click "Forgot username or password?" at the login screen. Follow the prompts to verify your identity using your account number, phone number, or email address.
Xfinity will send you a link to reset your account password. Once you have set a new account password, you can log back into the app or web portal and change your WiFi password as described above.
View your WiFi password without changing it
If you need to see your current WiFi password but do not want to change it, you can view it in the same WiFi Settings area where you would change it. In the Xfinity app, go to Internet > WiFi Settings and look for the password field — it may be hidden behind a "show" or eye icon. On the web portal, the password appears in the same location.
You can also find your default WiFi password on a sticker attached to your modem or gateway device. The sticker shows both the network name and the password that came with the device from the factory. If you have changed the password since then, the sticker will not show your current one.
What happens when you reset your modem to factory settings
If you reset your modem or gateway to factory settings — either by holding the reset button on the back of the device or through the Xfinity app — your custom WiFi password will be erased. The modem will revert to the default network name and password printed on the sticker attached to the device.
Resetting the modem should be a last resort for troubleshooting internet connection problems, not for changing your WiFi password. If you accidentally reset your modem, you can change the password back to what you want by following the steps in the sections above.
Reconnect your devices after changing the password
After you change your WiFi password, any device that was already connected to your network will stay online. When that device tries to connect again — after you restart it or it loses signal — it will ask for the new password. You will need to enter the new password to reconnect.
Go to your device's WiFi settings, find your Xfinity network name in the list, and select it. When prompted for the password, type the new one you just set. The device will connect and remember the password for future connections.
Frequently Asked Questions
How long does it take for the new WiFi password to work?
The new password takes effect within a few seconds of saving it. You can start using it to connect devices right away. You do not need to wait, restart your modem, or do anything else.
Can I change my WiFi password from my phone if I am not home?
Yes. As long as you have internet access on your phone — through cellular data or another WiFi network — you can log into the Xfinity app or xfinity.com and change your password from anywhere. The change takes effect when ready on your home network.
What if I set a new WiFi password and forgot it?
You can view your current WiFi password by logging back into the Xfinity app or web portal and going to WiFi Settings. You do not need to reset your modem or change the password again — just look it up the same way you would change it.
Will changing my WiFi password affect my internet speed?
No. Your WiFi password only controls who can connect to your network. Changing it does not affect your internet speed, your service plan, or your modem's performance.
Can I change my WiFi password if I do not remember my Xfinity account password?
No. You must log into your Xfinity account to access WiFi settings. If you have forgotten your account password, reset it at xfinity.com using your account number, phone number, or email address before you try to change your WiFi password.
