Usage: vault auth [options]

  Outputs instructions for authenticating with vault.

  Vault authentication is always done via environmental variables. The
  specific environmental variables and the meaning for each environmental
  variable varies depending on the auth mechanism that Vault is using.
  This command outputs the mechanism vault is using along with documentation
  for how to authenticate.

Options:

  -method=name    Outputs help for the authentication method with the given
                  name for the remote server. If this authentication method
                  is not available, exit with code 1.
