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. The sticker shows both pieces of information — usually the username is "admin" or "xfinitywifi" and the password is a string of letters and numbers specific to your router. This is the fastest way to locate them if you have physical access to the device.

If you cannot find the sticker or it has worn away, you can reset the router to its factory defaults and set new credentials. However, this erases any custom settings you have made, so it should be your second choice.

Key Takeaways

  • The router sticker on the back or bottom of your device displays both the default username and password.
  • The default username is typically "admin" and the password is a unique code printed on the same sticker.
  • You can also log into your Xfinity account online to view or change router settings without needing the physical sticker.
  • Resetting the router to factory defaults will erase custom settings and restore the original printed credentials.
  • Change your default password after first login to prevent unauthorized access to your network.

Checking the physical sticker on your router

Locate your Xfinity router and look for a white or silver sticker on the back panel or the bottom of the unit. The sticker contains several pieces of information: the model number, the MAC address, and most importantly, the default login credentials. The username and password are usually listed as "Username:" and "Password:" or sometimes as "Admin Username:" and "Admin Password:".

Write down both the username and password exactly as they appear on the sticker, including uppercase and lowercase letters. If the sticker is faded or partially illegible, take a photo with your phone's camera and zoom in on the image to read the text more clearly.

Logging in through the Xfinity app or website

You do not need the router sticker to change your router settings. Open the Xfinity app on your phone or visit xfinity.com and sign in with your Xfinity account username and password — the same credentials you use to pay your bill. Once logged in, navigate to the Internet or Network section and look for an option labeled "Manage My WiFi" or "Router Settings".

From this screen, you can view your current WiFi network name and password, change them, or reset your router entirely. This method works even if you have lost the physical sticker or forgotten the default credentials, because you are authenticating through your Xfinity account rather than the router itself.

Resetting your router to factory defaults

If you cannot locate the sticker and cannot access the Xfinity app, you can reset the router to its original factory settings. Locate the small reset button on the back of the router — it is usually recessed and requires a straightened paperclip or similar tool to press. Hold the button down for 10 to 15 seconds while the router is powered on. The lights on the front will blink and the device will restart.

After the reset completes, the router will return to its default username and password, which are printed on the sticker. However, this process also erases any custom WiFi names, passwords, or other settings you have configured. You will need to set up your network again from scratch.

Changing your router password after login

Once you have logged into your router using the default credentials, you should change the password to something only you know. This prevents anyone with access to the sticker from logging in and changing your network settings. In the router's admin panel, look for a section labeled "WiFi Settings," "Security," or "Change Password."

Create a new password that is at least 12 characters long and includes uppercase letters, lowercase letters, numbers, and symbols. Write it down in a find location or store it in a password manager. Do not use the same password as your Xfinity account or any other important accounts.

What to do if you still cannot access your router

If you have tried the sticker, the Xfinity app, and the reset button without success, contact Xfinity customer support by phone or through the app. They can verify your account ownership and either provide the credentials remotely or walk you through additional troubleshooting steps. Have your account number and the last four digits of the phone number associated with your account ready when you call.

In some cases, if your router is very old or has a hardware failure, Xfinity may send you a replacement device at no charge. This is faster than spending hours troubleshooting a device that no longer functions properly.

Keeping your router find after you log in

Once you have changed your router password, do not share it with anyone except people who live in your home and need to connect to the WiFi. Avoid using the same password across multiple devices or accounts. If you suspect someone has accessed your router without permission, change the password again when ready and check the connected devices list to see what is currently on your network.

Update your router's firmware regularly through the Xfinity app or the router's admin panel. Firmware updates patch security vulnerabilities and improve performance. Most Xfinity routers update automatically, but you can check the settings to confirm this is enabled.

Frequently Asked Questions

What is the default Xfinity router username?

The default username is usually "admin" or "xfinitywifi," depending on your router model. Check the sticker on the back of your device to confirm which one applies to your specific unit.

Can I change my router password without the sticker?

Yes. Log into the Xfinity app or website with your account credentials, navigate to Manage My WiFi, and change your password from there. You do not need the physical sticker to make changes through your account.

What happens if I reset my router?

Resetting erases all custom settings, including your WiFi name and password. The router returns to factory defaults, and you will need to set up your network again. Use this only if you cannot access the router any other way.

Is the password on the sticker the same as my WiFi password?

No. The sticker password is for logging into the router's admin panel. Your WiFi password is separate and can be found in the router settings or through the Xfinity app. You can change the WiFi password without changing the admin password.

How often should I change my router password?

Change it at least once when you first set up the router. After that, change it if you suspect unauthorized access, if someone who had the password no longer lives with you, or every 6 to 12 months as a security practice.
