Is it possible to add it to ssh-agent once?

[capitol_ → gtirloni]

No, the idea behind yk-backed keys are that part of the secret lives on the yubikey and can't be extracted.

So you need to approve the usage of that secret by touching the yubikey.

Well, if it's the same git server using the same SSH key for every repo, can't you still use SSH's ControlMaster to open the connection once and leave it open?

[noperator → jmholla]

Yeah could do. I do this for some SSH hosts but not all.
