Change your Xfinity WiFi password through the Xfinity My Account app or website

You can change your WiFi password yourself without calling Comcast. The fastest way is through the Xfinity My Account app on your phone, or through the web portal at xfinity.com. Both routes take about five minutes and let you set a new password immediately — your devices will disconnect and you'll need to reconnect using the new password.

You can also change it through your router's admin panel if you prefer not to use the Xfinity app, though this method requires you to know your router's admin login. Most people find the app or website simpler because you don't need to remember a separate password.

Key Takeaways

  • Log into your Xfinity account through the My Account app or xfinity.com, then find the WiFi settings section to create a new password.
  • Your new password takes effect immediately, and all connected devices will disconnect and need to reconnect with the new password.
  • You can change your password as often as you want — there's no limit on how many times you do this.
  • If you forget your Xfinity account password, use the "Forgot username or password" link on the login page to reset it before you can change your WiFi password.
  • If you change your password and can't reconnect, restart your router by unplugging it for 30 seconds, then plug it back in.

Change your password through the Xfinity My Account app

Open the Xfinity My Account app on your phone and sign in with your Xfinity username and password. Tap the menu icon (three horizontal lines) at the bottom right, then select "Internet" or "WiFi Settings" depending on your app version.

Look for "WiFi Network Name & Password" or "Change WiFi Password" — the exact label varies by app version. Tap it, then enter your new password in the field provided. Your password must be at least 8 characters long. Tap "Save" or "Confirm," and your new password is live immediately.

Change your password through xfinity.com

Go to xfinity.com and sign in with your Xfinity username and password. Click your account name or profile icon in the top right corner, then select "My Account" or "Account Settings."

Look for "Internet" or "WiFi" in the menu on the left side. Click "WiFi Network Name & Password" or "Manage WiFi." You'll see your current network name (SSID). Click the option to change your password, enter your new password (at least 8 characters), and click "Save." The change takes effect within a few seconds.

Change your password through your router's admin panel

If you prefer to change the password directly on your router, open a web browser and type 192.168.0.1 or 192.168.100.1 into the address bar. You may also see your router's IP address printed on a sticker on the back or bottom of the device.

Log in using your router's admin username and password. These are often printed on the router itself or in the paperwork that came with it. Look for "WiFi Settings," "Wireless," or "Security" in the menu. Find the field labeled "Password," "Pre-Shared Key," or "Passphrase," enter your new password, and click "Apply" or "Save." Your router may restart, which takes a minute or two.

What happens after you change your password

All devices currently connected to your WiFi will disconnect immediately. Your phone, laptop, tablet, smart TV, and any other connected devices will show that the network is available but won't be able to connect until you enter the new password.

Go to your WiFi settings on each device, select your Xfinity network name, and enter the new password. Devices will remember the new password after you enter it once, so you won't need to re-enter it unless you change the password again.

Troubleshooting if you can't reconnect after changing your password

"Incorrect password" errors usually mean you typed the new password wrong when reconnecting, or your device is still trying to use the old password. Forget the network on your device (in WiFi settings, select your network and choose "Forget"), then reconnect and enter the new password carefully.

If multiple devices can't connect, restart your router by unplugging it from power for 30 seconds, then plug it back in. Wait two to three minutes for it to fully restart. If you still can't connect after restarting, log back into your Xfinity account and double-check that the password change was saved — sometimes the change doesn't go through if your internet connection dropped during the process.

Frequently Asked Questions

What if I forgot my Xfinity account password?

Go to xfinity.com and click "Forgot username or password" on the login page. Enter your phone number or email address associated with your account, and Xfinity will send you a reset link. Follow the link to create a new account password, then use that to log in and change your WiFi password.

Can I change my WiFi password if I'm not the account holder?

No. Only the account holder or someone with the account holder's Xfinity login can change the WiFi password through the app or website. If you live in the home but aren't the account holder, ask them to change it for you or give you their login credentials.

How often can I change my WiFi password?

You can change it as many times as you want with no restrictions. There's no waiting period between changes, and Xfinity doesn't limit how frequently you do this.

Will changing my WiFi password affect my internet speed?

No. Changing your password doesn't change your internet speed or service. It only changes the password people need to connect to your WiFi network.

What makes a strong WiFi password?

Use at least 8 characters and mix uppercase letters, lowercase letters, numbers, and symbols (like ! or #). Avoid using your name, address, or common words. A strong password like "BlueSky#42Lamp" is harder to guess than "password123."
