Hello @Mallesh Prabhu,
Thank you for posting your query on Microsoft Q&A.
Based on your description, I understand that the user is encountering difficulty when attempting to log on to a Windows device using FIDO2 security key Passwordless authentication. An error message is displayed, stating: “Your credentials couldn't be verified. (code: 0xc000005f, 0x0).”
This issue can occur when the user falls under unsupported scenarios mentioned in the following documentation:
Unsupported Scenarios for FIDO2 Security Keys
I would like to highlight one unsupported scenario that I have encountered before in a similar case. Please refer the below screenshot.
Please ensure that the FIDO2 security key does not have multiple credentials stored. If it does, try configuring it with only one credential and then check the behavior while logging into the Windows device.
If the issue persists, try running dsregcmd /status
on the client machine and check if OnPremTgt and CloudTgt show YES in the SSO state.
Additionally, check the event viewer logs under Applications and Services >> Microsoft >> Windows >> WebAuthN >> Operational and share the information shown in the event viewer log.
I hope this information is helpful. Please feel free to reach out if you have any further questions.
Please Accept the answer
if the information helped you. This will help us and others in the community as well.
Thanks,
Raja Pothuraju.
