What is Publickey password?

Public Key Authentication is a secure logging method using SSH. Instead of a password, the procedure uses a cryptographic key pair for validation. Although using a strong password helps prevent brute force attacks, public key authentication provides cryptographic strength and automated passwordless logins.

What is OpenSSH public key format?

An SSH2 public key in OpenSSH format will start with "ssh-rsa". The idea behind all of this is that once you have keys on the remote server and your local host, access will be simpler since the server will only grant access to someone who has the matching private key.
