failed set-up of a passkey for a personal MS account

After scanning the QR code (on the PC screen) in the Authenticator app on the Iphone, the error message “Error adding the passkey - Microsoft Authenticator does not support this passkey” (translated from German) appears.

 What does this mean ?  How to prevent?

Any help is appreciated.

    Hi Reger, 

    im facing the same issue. I try to add passkey from amazon, ebay and telekom for example with no success. im also noticed that im not able to add a passkey to my microsoft account too. Same error all the time. 

    The solution hints from kidd_ip are not very helpful and does not match. Did you find any solution of this?

    best,

    Try to fix by below steps:

     

    • Update the Authenticator App: Ensure that you have the latest version of the Microsoft Authenticator app installed on your iPhone. Sometimes, updates include fixes for such issues.
    • Check iOS Version: Make sure your iPhone is running the latest version of iOS. Compatibility issues can sometimes be resolved with an update.
    • Re-register the Passkey: Try removing the existing passkey (if any) and re-registering it. Sometimes, re-registering can fix issues with passkey registration.
    • Use Security Info Portal: If the issue persists, try setting up the passkey through the Security Info portal on your iPhone instead of directly through the Authenticator app.
