How to Use a Passkey as One of the Shares in MPC

Help - Core-Kit tKey JS SDK
1

Hello,

Could you please explain how to use a passkey as one of the shares in MPC Core Kit or tKey?
I saw in the documentation that a passkey can be used as MFA, but I couldn’t figure out how to implement it.
Here is the link to the relevant documentation: MFA Flows.

I’d like to use a passkey as a share to enhance security, but I’m unsure how to proceed. If you have any examples or further details on the implementation process, I’d greatly appreciate your guidance.

Thank you in advance for your help!
