Frequently Asked Questions

Why does the Windows Hello security key challenge expire?

The challenge has a built-in cryptographic time limit designed for your security. If the YubiKey is not activated (tapped) quickly enough after the prompt appears, the session times out and throws an expiration error to prevent unauthorized access.

Should I post this error in the Microsoft 365 community?

No. Because this is a core operating system issue related to Windows Hello and device credentials, you will get better help by posting it in the Microsoft Q&A Windows community with the appropriate OS tags.

Can I use my YubiKey on a different computer?

Yes, YubiKeys are hardware-based and can be registered across multiple devices. Testing the key on another Windows PC can help you determine if the issue lies with the YubiKey itself or your specific computer's Windows Hello configuration.
