So I currently don't have a working HDMI port which is why i'm not able to connect my xbox to my monitor that i use. I use the xbox app on my laptop to connect to my xbox and stream the game that way I can still play. It's been working perfectly fine for a while, but now it is saying i need additional authentication on my xbox when i try to connect it from my xbox app, and I dont know how to fix it. I dont have the money to replace the HDMI port , and I dont really know what to do here. It's not like I can go and actually use the xbox by itself without the xbox app so im basically stuck with nothing to do here

Hi Besi Dolar,

Welcome to Xbox Forums. We appreciate for sharing your concern with us and we hope that you are doing well today.

The “Additional Authentication Needed” error on Xbox can prevent you from connecting to the internet on your console. It can be caused by several factors, such as your console’s region, Microsoft account, Xbox Live account, MAC address, or router settings.

To fix it, you can try clearing the alternate MAC address on your console, using your PC’s physical address as the dedicated MAC address on your console, or logging into your router settings and disabling access control or removing your console from the blocked devices list. You can find more instruction in this article. Running into the Additional authentication needed message? Check here! - Microsoft Community.







Performing a power cycle can also help you fix this issue. Power cycling is the act of turning a piece of equipment off and then on again. Reasons for power cycling include having an electronic device reinitialize its set of configuration parameters or recover from an unresponsive state of its mission-critical functionality, such as in a crash or hang situation.

1. Press and hold the Xbox button on the front of the console for 10 seconds.
   
2. Once the console is off, unplug the power cord from the back.
   
3. Wait 30 seconds, then plug the power cord back in.
   
4. Turn on your Xbox One.
   

We hope it worked out well for you. If not, please reply back to this forum to let us know so we could find other options to resolve the problem.



We will be glad to follow up and help you.

Sincerely,

Are you connecting your console to a hotspot, or a guest network at a hotel, which are secured by a captive portal (authentication web page)?

The second option require you to spoof the MAC address of an already associated/authenticated/authorized device and not the MAC address of whatever interface you're using to connect your Xbox (ethernet/wireless).

Also, make sure you're not concurrently connected with the current associated/authenticated/authorized device and your console, as they use the very same layer 2 identity.

Hi Kevin,

Every hardware device that connects to a network has an identifier code that is called a MAC address. This is how devices recognize each other because every device has a set and unique MAC address, unlike an IP address that cycles and changes periodically.

If I'm not mistaken the additional authentication required is your internet provider asking for your Xbox's MAC address to add it to the approved list of devices that your router allows to connect to. When you select the authenticate now button, it will
not load the page since it's trying to load a secure site that your ISP would authenticate the MAC address by first signing in to your router settings.

We have seen higher instances of this happening with AT&T for some reason, but essentially you need to make sure with AT&T that your Xbox is not being MAC filtered out from your router.

Before contacting AT&T, I suggest troubleshooting the console's MAC address and see if makes the Xbox more discoverable. Go to Settings>Network>Network Settings>Advanced Settings>Alternate MAC address>Clear and then select Restart Now when prompted.

If that doesn't work, call AT&T and ask for assistance with making sure your Xbox is not being filtered out. The console's MAC address can be found under the Advanced settings so have that ready when contacting your provider.
