If you need to log in to your Comcast Xfinity modem or gateway and you do not know the password, you are not alone. Every Xfinity gateway ships with default credentials printed right on the device. There are actually two different passwords you may need: the admin password for accessing your modem settings and the WiFi password that connects your devices to the internet. This guide shows you exactly where to find both.
Key Takeaways
- The default admin login for most Xfinity gateways is username "admin" and password "password," and you access it by typing 10.0.0.1 into a web browser.
- Your default WiFi network name and password are printed on the white sticker on the bottom or back of your Xfinity gateway.
- You can also view or change your WiFi password at any time through the Xfinity app on your phone without needing to touch the modem.
Two Passwords, Two Different Purposes
Before you start, it helps to understand that your Xfinity modem or gateway has two separate passwords. The first is the admin password, which lets you log in to the modem's settings panel to change network configurations, update firmware, or adjust security options. The second is the WiFi password, which is what you type into your phone, laptop, or tablet to connect to the internet. Most people looking for their "modem password" actually need the WiFi password, but we will cover both below.
How to Find the Default Admin Password
Check the Device Label
Some Xfinity gateways print the default admin credentials on the label sticker located on the bottom or back of the unit. Look for a section that says "Admin" or "Login." If it is listed, write it down. On most Xfinity gateways, however, the admin credentials are not printed on the label and instead use a universal default.
Use the Universal Default Login
For the majority of Xfinity xFi Gateways and older Xfinity modems, the default admin login credentials are the same across all units.
Follow these steps to log in:
1. Connect a device to your Xfinity network using WiFi or an Ethernet cable.
2. Open a web browser such as Chrome, Safari, or Edge.
3. Type 10.0.0.1 in the address bar and press Enter.
4. At the login screen, enter the following:
Username: admin
Password: password
5. Click Sign In.
This will take you to the Xfinity Gateway admin panel, sometimes called the Xfinity xFi Gateway Admin Tool. From here you can view and change your network settings, WiFi password, security mode, and other options.
If "admin" and "password" do not work, the default credentials may have been changed at some point. In that case, you may need to factory reset the gateway to restore the original defaults. See the reset instructions further down in this article.
How to Find Your Default WiFi Password
Check the Device Label
The fastest way to find your WiFi password is to look at the sticker on the bottom or back of your Xfinity gateway. Every unit ships with a unique default WiFi network name (SSID) and password printed on this label. Look for a section that says "Network Name" or "SSID" and "Password" or "Network Key." This is the password you enter on your devices to connect to your home WiFi.
Find the WiFi Password in the Admin Panel
If the label is missing or unreadable, or if the WiFi password has been changed from the default, you can look it up in the modem's admin panel.
1. Log in to 10.0.0.1 using the admin credentials described above.
2. Navigate to Gateway and then Connection and then WiFi.
3. Your current WiFi network name and password will be displayed on this page.
4. If you want to change the password, you can edit it here and click Save.
Note that the menu layout may vary slightly depending on your specific gateway model, but the WiFi settings are typically found under Connection or Wireless settings.
Find the WiFi Password in the Xfinity App
The Xfinity app is the easiest way to view or change your WiFi password without needing to log in to the admin panel directly. This method works from anywhere, even when you are not at home.
1. Download the Xfinity app from the App Store or Google Play if you have not already.
2. Sign in with your Xfinity account username and password (this is your Comcast billing account, not your WiFi password).
3. Tap WiFi at the bottom of the screen or from the main menu.
4. Tap View WiFi Password or tap your network name to see the details.
5. Your current WiFi network name and password will be displayed. You can also tap Edit to change either one.
Changes made through the Xfinity app take effect within a few seconds. Keep in mind that if you change your WiFi password, all currently connected devices will be disconnected and you will need to reconnect each one with the new password.
What to Do If the Default Password Does Not Work
If neither the default admin credentials nor the WiFi password on the label are working, someone likely changed them at some point. You have two options.
Option 1: Reset the WiFi Password Through the Xfinity App
If you can still log in to the Xfinity app with your Comcast account, you can change the WiFi password to something new without needing access to the admin panel. Follow the Xfinity app steps above and tap Edit to set a new password.
Option 2: Factory Reset the Gateway
A factory reset will restore all settings on the gateway back to the original defaults, including both the admin password and the WiFi password.
1. Locate the small Reset button on the back of your Xfinity gateway. It is usually recessed and requires a paperclip or pin to press.
2. Press and hold the Reset button for approximately 30 seconds.
3. Release the button and wait for the gateway to fully restart. This can take 5 to 10 minutes.
4. Once the lights stabilize, use the default credentials printed on the device label to connect.
Keep in mind that a factory reset will erase any custom WiFi network names, passwords, port forwarding rules, and other settings you may have configured. You will need to set everything up again after the reset.
Default Login Credentials by Xfinity Gateway Model
Most Xfinity gateways use the same default admin login. Here is a quick reference for the most common models.
Xfinity xFi Gateway (XB6, XB7, XB8)
Admin URL: 10.0.0.1
Username: admin
Password: password
WiFi Password: printed on device label
Xfinity Wireless Gateway (older Arris/Technicolor models)
Admin URL: 10.0.0.1
Username: admin
Password: password
WiFi Password: printed on device label
Xfinity xFi Advanced Gateway (XB8)
Admin URL: 10.0.0.1
Username: admin
Password: password
WiFi Password: printed on device label
If you own your own modem instead of renting one from Xfinity, the default admin credentials will be different and depend on the manufacturer. Check the label on your device or refer to the manufacturer's documentation.
Tips for Managing Your Xfinity Passwords
After you locate or reset your passwords, take a moment to set yourself up so you do not run into this issue again. Change the default admin password from "password" to something more secure to prevent unauthorized access to your gateway settings. Write down your WiFi password and keep it somewhere accessible like a note in your phone or taped inside a cabinet near the router. If you manage your network through the Xfinity app, make sure your Comcast account login is up to date so you can always access your WiFi settings remotely.
Frequently Asked Questions
What is the default login for a Comcast Xfinity modem?
The default admin login for most Xfinity gateways is username "admin" and password "password." You access it by going to 10.0.0.1 in a web browser while connected to the network.
Where is the WiFi password on my Xfinity modem?
The default WiFi password is printed on a sticker on the bottom or back of your Xfinity gateway. It is listed next to the network name (SSID). If the password has been changed, you can find the current one in the Xfinity app or by logging in to 10.0.0.1.
How do I find my Xfinity WiFi password on the app?
Open the Xfinity app, sign in with your Comcast account credentials, and tap WiFi from the main menu. Your current network name and password will be displayed. You can also change the password from this screen.
What do I do if the default admin password does not work on my Xfinity gateway?
If "admin" and "password" do not work at the 10.0.0.1 login page, the credentials were likely changed. You can restore the defaults by pressing and holding the Reset button on the back of the gateway for 30 seconds. After it restarts, the default login will work again.
Is 10.0.0.1 the IP address for all Xfinity modems?
Yes, 10.0.0.1 is the default gateway IP address for virtually all Xfinity-issued modems and gateways. Type this into your browser's address bar while connected to the network to access the admin panel.
Can I change my Xfinity WiFi password without logging into the modem?
Yes. You can change your WiFi password through the Xfinity app using your Comcast account login. This works from anywhere and does not require you to access the admin panel at 10.0.0.1.
What happens when I factory reset my Xfinity gateway?
A factory reset restores the gateway to its original out-of-the-box settings. This means the admin login will revert to "admin" and "password," the WiFi name and password will revert to what is printed on the device label, and any custom configurations like port forwarding will be erased.
