How to Change the Root Password in Linux

When to change the root password

Logged in as root (or via sudo), one command does it — then harden:

1. Change it — passwd (as root) or sudo passwd root
2. Enter twice — the new password never echoes; length beats complexity
3. Other users — sudo passwd username changes any account
4. Lost password — recover via your provider's VNC/console, or GRUB recovery mode on a VPS you control
5. After the change — verify SSH keys still work, review PermitRootLogin, and keep sudo users current

Password resets are reactive; SSH key login with password auth disabled is the preventive fix. Our VPS server consoles make recovery possible even when SSH is locked out, and the fail2ban guide keeps brute-force bots from ever getting close.

Method — change when logged in (passwd, sudo)
