Password authentication

As explained in Road to Kubernetes

A password is a secret authentication credential used to verify a user's identity.

How Road to Kubernetes covers it

How deep it goes

Defines passwords as SSH credentials and identifies their login role, but does not explain storage, policy, or password management.

Examples

Uses a root password with the `ssh root@172.104.195.109` command and a first-connection host-authenticity confirmation.

What it assumes

Assumes access to a remote host, its IP address or domain, a username, and a network connection; introduces passwords alongside SSH keys.

What you can do after

Apply it via SSH to authenticate as root when connecting to the specified remote virtual machine.

How it connects

Connects password authentication with SSH, remote hosts, usernames, root users, and SSH keys.
