ssh-sk-helper(8)

ssh-sk-helper8

Openssh helper for fido authenticator support

Usage

ssh-sk-helper [-v]

Overview

ssh-sk-helper is used by ssh(1), ssh-agent(1), and ssh-keygen(1) to access keys provided by a FIDO authenticator.

ssh-sk-helper is not intended to be invoked directly by the user.

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(1), ssh-agent(1), and ssh-keygen(1) will automatically pass the -v flag to ssh-sk-helper when they have themselves been placed in debug mode.
