Is it possible to do SSH without authorization at all? Without password and key?

Question

SSH

Hello! The question arose - is it possible to remove any authorization from port 22 (OpenSSH) at all? So that this command would immediately establish a connection
ssh [email protected]
. I understand that this is not safe, but security is not required here. And there is no way to enter a password or upload authorization keys to the client.
Is there a possibility to implement this?

Answer 1

sshpass -p password ssh -o StrictHostKeyChecking=no [email protected]

Answer 2

In /etc/ssh/sshd_config set PermitEmptyPasswords Yes and reload the ssh daemon?
