I am trying to use my ssh key with touchID. As others suggested here, I ran
ssh-add -K ~/.ssh/[my-private-key] and modified my
Host * UseKeychain yes AddKeysToAgent yes IdentityFile ~/.ssh/id_rsa
which works and makes my key available from the Keychain however it doesn't force me to provide my fingerprint. I would like to force the usage of TouchID to unlock my key every time when I try to ssh in, or at least once after opened the terminal client.
