NAME
ssh-sk-helper — OpenSSH helper for FIDO authenticator support
SYNOPSIS
ssh-sk-helper [-v]
DESCRIPTION
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.
