Use this command to specify that SSH users are not to be authenticated using passwords. This is typically done in order for SSH users to be authenticated using shared public keys instead. Shared public key authentication is less susceptible to brute force guessing of common passwords. If password authentication is disabled then shared public keys must be configured for user authentication. For information on configuring public keys for user authentication see Ciena Vyatta Network OS Basic System Configuration Guide.
