[2023] authentication error

Hi there @MagentaMink8849, thank you for reaching out! I'd like to look into this further and help if I can

First, please take the time to log in to our website and confirm that your accounts are linked properly. Once that has been done, I would like to suggest some quick tips and steps that should help to solve this problem for you. If you haven't tried these yet, please take the time to complete the following troubleshooting steps in this order:

• Launch Ubisoft Connect as an admin from the .exe
• Launch Rainbow Six Siege as an admin from the .exe

If that doesn't fix the issue, we can clear the ownership file then launch as admin again:

• Navigate to the following default directory >> C:\Program Files (x86)\Ubisoft\Ubisoft Game Launcher\cache\ownership
• Delete all files located in the ownership folder
• Launch Ubisoft Connect and Rainbow Six Siege as admin again

If you still encounter this authentication error, please do a clean reinstall of Ubisoft Connect for good measure. If you still need assistance after that, we'll need to proceed through private channels for security reasons. Please log in to our support website and create a new support case so we can follow up with you directly. To save time, please attach your launcher log file to your support case and include any other email addresses or usernames that you may have used in the past. Once an agent from our support team has reviewed everything, they will contact you to proceed further.
