+You can specify to use windows-fido-bridge on a per-host basis in your client
+ssh config file. That way you don't need any special commands to connect to the

+
+```
+Host myserver
+  HostName myserver.mydomain.org
+  IdentityFile ~/.ssh/id_ed25519_sk
+  SecurityKeyProvider=/usr/local/lib/libwindowsfidobridge.so
