Change the default password after logging in

Default credentials for Xfinity (Comcast) routers are publicly documented, so if your router still uses one, change the admin password immediately to a strong, unique password. Leaving the default in place lets anyone on your network reconfigure the router. Many newer Xfinity (Comcast) models instead ship with a unique password printed on the device label - if yours does, use that.

Open a browser and go to http://10.0.0.1, then sign in with the credentials above. For a step-by-step walkthrough, see how to log in to 10.0.0.1. If you don't know a changed password, you can reset the router to restore the default.

Frequently asked questions

What is the default password for a Xfinity (Comcast) router?

Comcast Xfinity xFi gateways open their admin tool at 10.0.0.1 with admin / password. Day-to-day management is intended to happen in the Xfinity app. Many newer routers also print a unique password on the device label, so check the sticker on your unit first.

What is the default IP address for a Xfinity (Comcast) router?

Xfinity (Comcast) routers most commonly use 10.0.0.1. Because the address can be changed, confirm it by checking your device's default gateway.

The default Xfinity (Comcast) password doesn't work - what should I do?

Either the password was changed, or your model uses a unique per-device password printed on the label. Check the sticker on the router, then factory reset it to restore the default credentials if needed.
