This error indicates that the workstation user may not be configured properly. This is typically not a production issue and may be experienced during sandbox or deployment testing by internal or pilot users.
This can be caused by an end user seeking to enroll a Security Key on a local user account.
Please follow these instructions in order to resolve the issue:
1. At this time, only domain joined user accounts are supported for certificate based Security Key login. Local user account enrollment for Security Keys are not currently supported without the use of a mobile app.
Why might I see error code 1550010 on my workstation when pairing a security key?
