Edit /etc/ssh/sshd_config and set the PermitEmptyPasswords parameter to no above any Include and Match entries as follows: PermitEmptyPasswords no Note: First occurrence of an option takes precedence, Match set statements withstanding. If Include locations are enabled, used, and order of precedence is understood in your environment, the entry may be created in a file in Include location. The SSH daemon must be restarted for the changes to take effect. To restart the SSH daemon, run the following command: # systemctl reload-or-restart sshd.service
