To configure password authentication for the SSH client, open the SSH client configuration file and check that password authentication is enabled. For an OpenSSH client, ensure that the PasswordAuthentication parameter is set to yes (default) in the $HOME/.ssh/config file.

For an OpenSSH client, also ensure that the StrictHostKeyChecking parameter is set to no in the $HOME/.ssh/config file, so that the SSH client automatically adds a new server host to the user’s database of known hosts without prompting for confirmation.
