Change the VM password

When you forget the password or need to rotate credentials, reset the VM's admin/root password straight from the Portal — no SSH session required.

Applies to
  • Linux — root password.
  • Windows — Administrator password.

The feature requires the in-VM agent (shipped by default in LANIT images). If the agent is unavailable, use Rebuild from base image or contact support.

Steps​

Step 1. Open the VM detail page​

Go to Cloud Server → Servers and click the VM.

Open the VM detail page

Step 2. Open the Thao tác tab​

Thao tác tab on the detail page

Step 3. Enter the new password​

Under Mật khẩu in the Truy cập card, type the password into Mật khẩu mới and Xác nhận mật khẩu. It should meet:

  • At least 8 characters.
  • Mix of upper-case, lower-case and digits.
  • Avoid dictionary words (password, admin, 123456…).

Click Đổi mật khẩu.

Enter the new password under Mật khẩu

Step 4. Confirm​

A confirmation dialog appears. Check Tự động khởi động lại sau khi đổi (Auto-reboot after changing) if you want the VM to reboot right away, then click Đổi mật khẩu again to finish.

A reboot is required to take effect

The new password only takes effect after the VM reboots. If you didn't check auto-reboot above, reboot the VM yourself afterwards.

Security recommendations​

  • Prefer SSH Key over passwords on Linux — see SSH Key.
  • Rotate the password on a schedule (90 days is a common cadence).
  • Don't reuse the same password across production VMs.
  • Store passwords in a password manager (1Password, Bitwarden…), never in plaintext files.
