Subject: Forza Horizon 4 - Authentication Error with Key Access/QR Code; Unable to Login

Hi everyone,

I’m experiencing a persistent issue with Forza Horizon 4 that’s preventing me from logging into the game.

Problem:

When the game prompts me to login, attempting to use the “Key Access” method (using the QR code with my iPhone/iPad/Android device) consistently results in an error message, something along the lines of “An error occurred while logging in with the access key.” (“There was an error when entering with a security key”). I cannot successfully authenticate using this method.

Crucially, now I can’t even log in with my email and password anymore.

What I’ve Tried:

  • Standard troubleshooting steps (restarting the game, restarting my PC, checking my internet connection).

  • Ensured that Windows is up to date.

  • Verified that the Xbox app on my phone is up to date (reinstalled it).

  • Attempted to use a different mobile device for QR code authentication (if applicable).

  • Checked basic account settings.

  • Disabling overlays.

  • Checking DNS

  • Nvidia driver

  • Processes

Important Information:

  • Forza Horizon 5 works perfectly fine. I can log into FH5 using the same account without any issues. This suggests the problem is specific to how FH4 handles authentication.

  • I’ve already contacted Forza Support but wanted to see if anyone else on the forums is experiencing the same issue.

  • I am running Windows [Your Windows Version].

  • I have [Your PC Specs - briefly mention if it’s a high-end or more typical system].

What I Suspect:

I strongly suspect that there’s an issue with the authentication mechanism in Forza Horizon 4 itself, specifically related to key access or QR code logins. It may be related to obsolete security libraries and something with the FH4 servers now.

Questions:

  • Has anyone else encountered this problem recently?

  • Are there any known workarounds or solutions?

  • Has anyone heard anything from Forza Support regarding this issue?

Any help or insights would be greatly appreciated. It’s frustrating not being able to play the game.

Thanks!

Key things to customize:

  • [Your Windows Version]: e.g., “Windows 10 64-bit”, “Windows 11”

  • [Your PC Specs]: Just a brief overview, e.g., “a mid-range gaming PC”, “a fairly powerful desktop”.

  • Error message: if you have the exact error message, include it.

This is a good starting point. Good luck! I hope you get some helpful responses on the forums.
