It depends on the specific model and capabilities of TrustKey's security key. Windows Hello primarily relies on biometric authentication methods such as facial recognition, fingerprint scanning, or PIN entry. Traditional FIDO U2F or FIDO2 security keys, including those from TrustKey, may not directly integrate with Windows Hello for these specific biometric functions.
TrustKey has released models (e.g. B210H) specifically designed to work with Windows Hello and includes biometric capabilities and you may be able to use it for Windows Hello authentication. It's essential to check the product documentation and specifications of your TrustKey model to determine its compatibility with Windows Hello and whether it supports the required biometric methods.
If in doubt, you can also contact TrustKey's support for clarification on the capabilities of your specific security key model.
