Linux/Unix: Force ssh client to use only password auth authentication when pubkey auth configured

To force an ssh client to use only password authentication when public key authentication is configured, you can use the ssh command with the -o PreferredAuthentications=password option.

For example, to connect to a remote host using only password authentication, you can use the following command:

ssh -o PreferredAuthentications=password user@remote_host

This will force the ssh client to use only password authentication when connecting to the remote host.

Note: This option may not work if the server has been configured to disable password authentication. In that case, you may need to use another authentication method, such as public key authentication or key-based authentication.

You can find more information about the ssh command and its options in the ssh documentation or by running the ssh --help command.
