Where to find your router credentials

Your Xfinity router username and password are printed on a sticker attached to the back or bottom of the device itself. Look for a white or silver label that lists "Username" (usually admin) and "Password" (a string of letters and numbers specific to your router). This is the fastest way to find them — you do not need to log into your Xfinity account or call support.

If the sticker is missing, faded, or you cannot locate the router physically, you have two other paths: reset the router to factory defaults, or retrieve the password through your Xfinity account online. Each method takes a different amount of time and carries different trade-offs.

Key Takeaways

  • The router username and password are printed on a sticker on the back or bottom of your Xfinity router device.
  • The username is almost always admin, but the password is unique to your router and cannot be looked up without the sticker or a factory reset.
  • Resetting your router to factory defaults will restore the original password but will disconnect all your devices and erase custom settings like WiFi name changes.
  • You can also retrieve your password through the Xfinity My Account app or website if you have your Xfinity account username and password.

Checking the physical sticker on your router

Unplug your router or leave it powered on — either way works. Flip the device over or look at the back panel. The sticker should be white, silver, or sometimes yellow. It will have lines labeled "Username" and "Password" (sometimes abbreviated as "User" and "Pass"). Write down both exactly as they appear, including capital letters and numbers.

The username is almost always admin for Xfinity routers. The password is a unique combination that Comcast assigns to your specific device during setup. If you see a QR code on the sticker, that is for WiFi setup, not router login — ignore it for now.

Once you have both, you can open a web browser on any device connected to your WiFi, type 192.168.0.1 or 192.168.100.1 into the address bar, and log in. If the sticker is completely illegible or missing, move to the next section.

Retrieving the password through your Xfinity account

Open the Xfinity My Account app on your phone or go to xfinity.com on a computer. Log in with your Xfinity account username and password — this is the same login you use to pay your bill, not the router login. Once inside, look for a section called "Internet" or "Devices" (the exact name varies by app version).

Find your router listed under connected devices or equipment. Tap or click on it, and you should see an option to view or reset the password. Some versions of the app show the password directly; others require you to confirm your identity first by answering a security question or receiving a code via text or email.

This method works only if you remember your Xfinity account login. If you have forgotten that password, you will need to reset it on the Xfinity website before you can proceed. This route typically takes five to ten minutes.

Resetting your router to factory defaults

If you cannot find the sticker and do not have access to your Xfinity account, you can reset the router to its original state. This will restore the default password, but it will also disconnect every device currently using your WiFi and erase any custom settings you made, such as a WiFi network name change.

Locate the small reset button on the back or bottom of your router — it is usually recessed so you cannot press it by accident. Use a paperclip, pen, or the tip of a thumbtack to press and hold the button for 10 to 15 seconds while the router is powered on. The lights on the front will blink, and the device will restart. This takes about two to three minutes.

Once the router finishes restarting, the username will be admin and the password will be the default password printed on a new sticker (or on the original sticker if it is still readable). You will need to reconnect all your devices to WiFi and reconfigure any custom settings you had before.

What to do if you still cannot log in

If you have tried the sticker, your Xfinity account, and a factory reset and still cannot access the router, contact Xfinity support by phone at 1-800-934-6489 or through the My Account app. Have your account number and the router model number (printed on the sticker) ready. Support can verify your identity and either reset the password remotely or walk you through additional troubleshooting steps.

In rare cases, the router itself may be malfunctioning or may have been set up under a different Xfinity account. Support can determine this and arrange a replacement if needed. This path typically takes 15 to 30 minutes on the phone.

Keeping your router password find after you log in

Once you have logged into your router using the default username and password, you should change the password to something only you know. This prevents neighbors or visitors from accessing your router settings. Most Xfinity routers have a "Change Password" or "Administration" section in the settings menu.

Write down your new password in a safe place — not in a browser autofill or a shared document. If you forget it later, you can always reset the router again, but that will erase your custom settings. Changing the router password is different from changing your WiFi password; both are worth doing, but they protect different things.

Frequently Asked Questions

Is the router password the same as my WiFi password?

No. The router password (username admin) lets you log into the router's settings page. Your WiFi password is what you give to guests to connect their phones and laptops to your network. They are separate and can be different. You can change either one independently.

What if the sticker says something other than "admin" for the username?

Xfinity routers use admin as the standard username. If the sticker shows something else, double-check that you are looking at the router sticker and not a modem sticker or another device. If you are certain it is the router and the username is different, contact Xfinity support — your device may have been customized during setup.

Will resetting my router affect my internet connection?

A factory reset will not break your internet connection to Comcast. Your modem (a separate device) handles that. However, the reset will disconnect all your WiFi devices and erase custom WiFi settings. You will need to reconnect each device and may need to reconfigure port forwarding or other advanced settings if you had them set up.

Can I change my router password without logging in?

No. You must log in to the router's settings page using the username and password to change either the router password or your WiFi password. If you cannot log in, your only options are retrieving the password through your Xfinity account or performing a factory reset.

Why does my router have two different IP addresses listed online?

Some Xfinity routers respond to both 192.168.0.1 and 192.168.100.1. Try the first one; if it does not work, try the second. Both will take you to the same login page. This is normal and not a sign of a problem.
