🔓 Enabling Root Login in Debian Control Panel (Debian 12 and 13)

✅ Steps to Enable Root Login

1. Edit the disallowed-users file
   Open the file with a text editor using root privileges:

sudo nano /etc/cockpit/disallowed-users

2. Remove or comment out the root line
   If you see a line that contains only:

root

comment out that line:

# root

3. Save the changes

• In Nano, press Ctrl+X, then Y, then Enter to save and exit.

4. Restart the Cockpit service

For the changes to take effect, restart Cockpit:

sudo systemctl restart cockpit

(Rebooting the system is optional but not typically necessary.)

⚠️ Important Considerations

• 🔐 Security Risks
  Enabling root login increases the attack surface. It's safer to use a non-root user with sudo privileges for daily tasks.

• 🔑 Alternative Authentication
  Consider implementing Kerberos, SSH keys, or certificates for more secure authentication.

• 🧱 Firewall Access
  Make sure your firewall allows traffic on TCP port 9090, which Cockpit uses.

• 👤 Managing Other Users
  You can restrict additional users by adding their usernames (one per line) to /etc/cockpit/disallowed-users.
