Server Management
Change Password — Ubuntu
The same core command as AlmaLinux, with Ubuntu's sudo conventions if you're logged in as a non-root user.
1
Connect to your VPS via SSH
Log in to your Ubuntu VPS using PuTTY or your preferred SSH client.
2
Run the passwd command
If you're logged in as root, run the command directly. If you're logged in as a regular user, prefix it with sudo:
bash
# As root passwd # As a sudo-enabled user, changing your own password sudo passwd $USER # As a sudo-enabled user, changing another user's password sudo passwd username
3
Enter and confirm the new password
Type the new password when prompted, then retype it to confirm. Ubuntu will show a success message once it's updated.
output
New password: Retype new password: passwd: password updated successfully
Ubuntu's password policy (via PAM) may reject passwords that are too short or based on dictionary words. If rejected, try a longer, more random password.
Test your new password in a fresh SSH session before closing your current one, to avoid getting locked out of your VPS.
