biometric token

Hello to everybody.

Has anyone ever implemented and configured a biometric token on Safeguard? What are the steps to integrate the token into Safeguard and use it as a second authentication factor to access SPP? I need to know step by step. Thanks a lot The token is 

YubiKey Bio – Fido Edition

(PS: if I understand correctly with this type of token only SPP login is possible, which might be sufficient, but if I need to use a biometric token to authenticate to activities in this way, what type of token should I consider)?

many thanks
