1. In terminal, first run
Code:
sudo su -

2. Then edit sshd config
Code:
nano /etc/ssh/sshd_config

3. Find these lines

#PermitRootLogin prohibit-password
PasswordAuthentication no

Change them respectively to these

PermitRootLogin yes
PasswordAuthentication yes

note: uncomment or remove the "#" character

Ctrl+X then Y then Enter to exit

4. Then restart sshd
