+SSH-SK-HELPER(8)            System Manager's Manual           SSH-SK-HELPER(8)
+
+NAME
+     ssh-sk-helper M-bM-^@M-^S OpenSSH helper for FIDO authenticator support
+
+SYNOPSIS
+     ssh-sk-helper [-v]
+
+DESCRIPTION
+     ssh-sk-helper is used by ssh-agent(1) to access keys provided by a FIDO
+     authenticator.
+
+     ssh-sk-helper is not intended to be invoked by the user, but from
+     ssh-agent(1).
+
+     A single option is supported:
+
+     -v      Verbose mode.  Causes ssh-sk-helper to print debugging messages
+             about its progress.  This is helpful in debugging problems.
+             Multiple -v options increase the verbosity.  The maximum is 3.
+
+             Note that ssh-agent(1) will automatically pass the -v flag to
+             ssh-sk-helper when it has itself been placed in debug mode.
