Change Your WiFi Password Through the Xfinity App or Website

You can change your Comcast WiFi password by logging into your Xfinity account on the Xfinity website or through the Xfinity app on your phone. The process takes about five minutes and you do not need to restart your modem or call customer support. Once you change the password, all devices currently connected to your WiFi will be disconnected and will need the new password to reconnect.

The fastest route is the Xfinity app if you have it installed. Open the app, tap the menu icon (three horizontal lines), select "Internet," then tap "WiFi Settings." From there you can see your network name and change the password directly. If you prefer the website, go to xfinity.com, sign in with your Comcast username and password, click "Internet" in the top menu, then select "WiFi Settings" from the left sidebar.

Key Takeaways

  • You change your WiFi password through the Xfinity app or website, not through your modem's settings page.
  • Your new password takes effect when ready, and every device connected to your WiFi will be disconnected and need to reconnect with the new password.
  • Your WiFi password is different from your Xfinity account password — changing one does not change the other.
  • If you cannot remember your Xfinity account password, you will need to reset it on the Xfinity login page before you can change your WiFi password.

Step-by-Step Instructions for the Xfinity App

Open the Xfinity app and tap the menu icon in the bottom right corner (three horizontal lines). Scroll down and tap "Internet." You will see a section labeled "WiFi Settings" — tap that. The app will show your current network name (SSID) and a button to change your WiFi password.

Tap the button to change your password. Enter a new password that is at least 8 characters long and includes a mix of uppercase letters, lowercase letters, numbers, and symbols if possible. Comcast recommends avoiding dictionary words and your account number. After you enter the new password, tap "Save" or "Confirm." The app will show a confirmation message, and your new password is now active.

Step-by-Step Instructions for the Xfinity Website

Go to xfinity.com and sign in with your Comcast username and password. Once you are logged in, click "Internet" in the top navigation menu. On the left side of the page, you will see a menu with several options — click "WiFi Settings."

The WiFi Settings page will display your network name and a link or button to change your WiFi password. Click that button. Enter your new password (at least 8 characters, mixing uppercase, lowercase, numbers, and symbols), then click "Save" or "Confirm." You will see a confirmation that your password has been updated. All devices will be disconnected within a few seconds.

What Happens After You Change Your Password

Every device currently connected to your WiFi — phones, laptops, tablets, smart TVs, smart speakers, printers — will lose connection when ready. You will need to reconnect each one by selecting your WiFi network name and entering the new password. Devices will not automatically reconnect even if they remember your old password.

If you have a smart home device like an Alexa speaker or Google Home that was connected to your old WiFi, you will need to go into that device's settings app and update the WiFi password there as well. The same applies to smart TVs, security cameras, and any other connected devices. Your modem does not need to be restarted.

If You Forgot Your Xfinity Account Password

If you cannot log into your Xfinity account, you cannot change your WiFi password through the app or website. Go to xfinity.com and click "Sign In" in the top right. Below the password field, click "Forgot your password?" Comcast will ask you to verify your identity using your phone number, email address, or account number.

After you verify your identity, Comcast will send you a link to reset your password. Check your email (including spam folders) for that link. Click it, create a new Xfinity account password, and then you can log back into the app or website to change your WiFi password. This process usually takes a few minutes.

Changing Your Password on the Modem Itself (Not Recommended)

Your Comcast modem has its own settings page that you can access by typing 192.168.0.1 into a web browser. This page is separate from your Xfinity account and is used for advanced modem settings. You can change your WiFi password there, but Comcast does not recommend it because changes made directly on the modem can be overwritten when Comcast pushes updates to your equipment.

If you do access the modem settings page, you will need to log in with the admin username and password, which are usually printed on the modem itself or on a sticker attached to it. For most Comcast modems, the default username is "admin" and the password is "motorola" or "comcast," though this varies by model. If you change your password this way, the change may not sync with your Xfinity account, which can cause confusion later.

Frequently Asked Questions

Will changing my WiFi password affect my internet speed or connection?

No. Your WiFi password only controls who can connect to your network. Changing it does not affect your internet speed, your modem's performance, or your connection to Comcast's network. The only change you will notice is that devices need to reconnect with the new password.

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 in a web browser, you can change your WiFi password from anywhere. You do not need to be connected to your home WiFi to make the change.

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

You can change it again using the same steps. Log into the Xfinity app or website and go to WiFi Settings. You do not need to know your current password to set a new one — you only need to be logged into your Xfinity account.

Is my WiFi password the same as my Xfinity account password?

No. Your Xfinity account password is what you use to log into xfinity.com or the Xfinity app. Your WiFi password is what guests and devices use to connect to your home network. You can change them independently of each other.

How often should I change my WiFi password?

There is no set rule. Many people change it once a year or whenever they suspect someone unauthorized has connected to their network. If you share your password with guests or family members who no longer visit, changing it is a straightforward way to cut off their access without affecting your own devices.
