How to connect to your xbox account on xbox 360 with the authenticator

how do you connect your xbox live account to your xbox 360?

802.1x authentication is not supported on the Xbox.

You might be able to use Internet Connection Sharing through your Mac, but I've never done this w/ OS X machines.
support.microsoft.com/.../978618 shows how to do it with PCs, so I'd do a web search for "Connect Xbox 360 through Mac"

Hi there,

If, on your account you have two-factor or multi-factor authentication on the account, you will have to create an app password to use to log into the 360.

Information on how to set it up can be found
here.

At this point, let's not discuss how your Belkin router, or your Motorola gateway should be properly setup, to work with one or the other, seamlessly, but instead concentrate on why your Xbox 360 can't connect through your Motorola gateway.

Try reset your Motorola gateway back to factory defualts. Consult the manual for your gateway, how to properly restore to factory settings. If your connection method requires authentication to your ISP (username and password), make sure you know the login
crendentials for your ISP.

On your Xbox 360, clear the Xbox system cache, and restore network settings to factory defaults (as mentioned in a previous post).

Turn off your console.

Use the same Ehternet Cable as you're using to connect your Xbox One, to your Motorola, and connect this Cable to your Xbox 360 instaed.

Turn on your console and head over to Network Settings and select Test Xbox Live Connection.

Let me know how that goes.

Greetings csmithster011!

If BT's FON service are using 802.1x, or RADIUS for the authentication method, then you will not be able to connect your console through this procedure, as you would do using your computer. The Xbox 360 do not support such authentication protocols.

There is a workaround for this, where you can choose to use your computer and share its Internet Connection with your console, or to use the physical address/MAC address of the already authenticated computer, and use this address as your consoles alternative
MAC address.
