Your Xfinity gateway has two default passwords. The WiFi password is printed on the label on the bottom or back. The Admin Tool at 10.0.0.1 uses username admin with that same label password on current gateways, or the word password on older units, and it must now be switched on in the Xfinity app.
Last updated September 1, 2026.
Key Takeaways
- Since early 2026, the 10.0.0.1 Admin Tool is turned off by default on Xfinity gateways. You enable it in the Xfinity app under WiFi, View WiFi equipment, Advanced settings, Admin Tool online access.
- The Admin Tool username is "admin." On current xFi Gateways (XB6 and newer) the password is the WiFi password printed on the label. On older units the default is "password."
- Your default WiFi network name and password are printed on the white sticker on the bottom or back of the gateway, and you can view or change them any time in the Xfinity app without touching the hardware.
Two Passwords, Two Different Purposes
Your Xfinity modem or gateway has two separate passwords. The first is the admin password, which opens the gateway's settings panel (the Admin Tool) so you can view connected devices, set up port forwarding, or switch to bridge mode. The second is the WiFi password, which is what you type into your phone, laptop, or TV to get online. Most people searching for their "modem password" need the WiFi password. Both are covered below, starting with the change that trips up most people in 2026.
First: Turn On the Admin Tool in the Xfinity App
If you type 10.0.0.1 into a browser and get a page telling you to download the Xfinity app instead of a login box, nothing is broken. Comcast disabled local Admin Tool access by default on its gateways in early 2026 and moved day-to-day settings into the app. The Admin Tool still exists, but you have to switch it on first.
1. Open the Xfinity app on your phone while connected to your home network.
2. Tap WiFi at the bottom of the screen.
3. Tap View WiFi equipment, then Advanced settings.
4. Tap Admin Tool online access and slide the toggle to Allow Admin Tool access.
5. Tap Save.
The toggle appeared in app version 5.62 in February 2026. If you do not see it, update the app. Two known gaps: the option does not show up when the gateway is in bridge mode, and some accounts still do not see the Advanced settings menu at all. In those cases Xfinity support can enable access on their end. Comcast's own steps are in its Admin Tool online access article.
How to Find the Default Admin Password
Check the Device Label
On current xFi Gateways, the Admin Tool password is the same password printed on the white sticker on the bottom or back of the unit, next to the default network name. Comcast made this change to stop every gateway shipping with the same universal login. Write it down before you need it; the label is easy to lose track of once the gateway is behind a TV stand.
Log In at 10.0.0.1
With Admin Tool access enabled, follow these steps:
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: the WiFi password on the gateway label
5. If that is rejected, try the older universal default:
Username: admin
Password: password
6. Click Sign In.
The Admin Tool on XB6 and newer gateways is now mostly read-only. You can see connected devices, signal levels, and the network map, but WiFi changes, port forwarding, DMZ, and DNS settings are managed in the Xfinity app. Older gateways still allow edits from the browser.
If neither password works, the admin password may have been changed at some point. A factory reset restores the label defaults; see the reset instructions further down.
How to Find Your Default WiFi Password
Check the Device Label
The fastest way to find your WiFi password is the sticker on the bottom or back of your Xfinity gateway. Every unit ships with a unique default network name (SSID) and password printed there. Look for "Network Name" or "SSID" and "Password" or "Network Key." This is the password you enter on your devices to connect to home WiFi. On current gateways it doubles as the Admin Tool password described above.
Find the WiFi Password in the Xfinity App
The Xfinity app is the easiest way to view or change your WiFi password, and it works from anywhere, even away from 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 login, not your WiFi password).
3. Tap WiFi at the bottom of the screen.
4. Tap View WiFi password or tap your network name to open its details.
5. Your current network name and password are displayed. Tap Edit to change either one.
Changes take effect within a few seconds. One password now covers both the 2.4 GHz and 5 GHz bands, so you no longer set them separately. Changing the WiFi password disconnects every device on the network, and each one will need the new password to reconnect.
Find the WiFi Password in the Admin Tool
If the label is unreadable and you would rather use a browser, log in at 10.0.0.1 as described above, then navigate to Gateway, Connection, WiFi. The current network name and password are shown on that page. On newer gateways the fields are display-only; use the app to edit them.
What to Do If the Default Password Does Not Work
If neither the label password nor "password" gets you into the Admin Tool, or the WiFi password on the label no longer connects, someone changed it at some point. You have two options.
Option 1: Reset the WiFi Password Through the Xfinity App
If you can sign in to the Xfinity app with your Comcast account, change the WiFi password to something new without touching the Admin Tool. Follow the app steps above and tap Edit.
Option 2: Factory Reset the Gateway
A factory reset restores every setting on the gateway to its out-of-the-box state, including the admin password and the WiFi name and password printed on the label.
1. Find the small recessed Reset button on the back of the gateway. It needs a paperclip or pin to press. Some newer models have no reset hole; on those, hold the WPS button instead.
2. Press and hold for a full 30 seconds.
3. Release and wait for the gateway to restart, which can take 5 to 10 minutes.
4. Once the lights settle, connect using the network name and password on the label.
A factory reset wipes any custom network names, passwords, port forwarding rules, and other settings you configured, and you will need to set up the Admin Tool toggle in the app again if you use it. If the label password still does not open the Admin Tool after a reset, that is a known issue on some XB8 units, and Xfinity support can check the gateway details on their side or swap the unit.
Default Login Credentials by Xfinity Gateway Model
The address and username are the same across every Xfinity-issued gateway. The admin password depends on the generation.
| Gateway | Admin URL | Username | Default admin password | WiFi password |
|---|---|---|---|---|
| xFi Gateway XB8 and newer | 10.0.0.1 | admin | Password on device label | Printed on device label |
| xFi Gateway XB6, XB7 | 10.0.0.1 | admin | Label password; "password" on older firmware | Printed on device label |
| Older Wireless Gateways (Arris, Technicolor) | 10.0.0.1 | admin | password | Printed on device label |
If you own your own modem instead of renting from Xfinity, none of this applies. Retail modems and gateways use the manufacturer's own address and login, usually 192.168.0.1 or 192.168.100.1 with the credentials on the device label or in the manual. Owning also means the Admin Tool toggle and the app-only settings above are not a factor; you manage the hardware directly. Our Xfinity compatible modems are tested, deregistered, and ready to activate.
Tips for Managing Your Xfinity Passwords
Once you have located or reset your passwords, set yourself up so this does not happen again. Photograph the gateway label and save it to your phone, since it now holds both passwords. If you enabled Admin Tool access, turn it back off in the app when you are done; leaving it on is a small security exposure Comcast chose to close by default. Keep your Comcast account login current so the app can always get you back into WiFi settings, and if you do change the WiFi password, pick something you can read aloud to a guest without spelling it twice.
If the reason you are digging through gateway settings is that the WiFi itself is the problem, the rented gateway may be the limit. The fix depends on what it is doing wrong.

Frequently Asked Questions
What is the default login for a Comcast Xfinity modem?
The address is 10.0.0.1 and the username is "admin." On current xFi Gateways the password is the WiFi password printed on the device label. On older gateways it is "password." Since early 2026 you must first enable Admin Tool access in the Xfinity app or the login page will not load.
Why does 10.0.0.1 tell me to download the Xfinity app?
Comcast turned off local Admin Tool access by default in February 2026. Open the Xfinity app, go to WiFi, View WiFi equipment, Advanced settings, Admin Tool online access, and switch the toggle on. Save, then reload 10.0.0.1.
Is the Xfinity admin password the same as the WiFi password?
On XB6 and newer gateways, yes. Both default to the password on the sticker. They only stay identical until you change the WiFi password in the app; the Admin Tool password keeps the original label value. On older gateways the admin password defaults to "password" and is separate from WiFi.
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, next to the network name (SSID). If it 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 in the app?
Open the Xfinity app, sign in with your Comcast account, and tap WiFi at the bottom. Tap View WiFi password or your network name. The current name and password are displayed, and you can change either one from that screen.
What do I do if the default admin password does not work?
Try the label password first, then "password." If neither works, hold the Reset button on the back of the gateway for 30 seconds to restore the defaults. If the label password still fails after a reset, contact Xfinity support; they can check the gateway on their end or swap it.
Is 10.0.0.1 the IP address for all Xfinity modems?
Yes, 10.0.0.1 is the default gateway address for virtually all Xfinity-issued modems and gateways. If the gateway is in bridge mode, the address behind it belongs to your own router instead, often 192.168.0.1 or 192.168.1.1.
Can I change my Xfinity WiFi password without logging into the modem?
Yes. Change it through the Xfinity app using your Comcast account login. This works from anywhere and is now the primary way Comcast expects you to manage WiFi settings.
What happens when I factory reset my Xfinity gateway?
A factory reset restores the gateway to its out-of-the-box settings. The admin login goes back to "admin" plus the label password (or "password" on older units), the WiFi name and password revert to what is printed on the label, and any custom settings such as port forwarding are erased.
