✅ Step 1: Set a Password for Root
sudo passwd root
•You'll be prompted to enter and confirm a new password for the root user.
•After this, the root account will be enabled.

sudo nano /etc/ssh/sshd_config
2.Find the line:
PermitRootLogin prohibit-password
3.Change it to:
PermitRootLogin yes
4.Save and exit (Ctrl+O, Enter, Ctrl+X).
5.Reload SSH:
sudo systemctl restart ssh
