Reset and restore the password of a dedicated server

Last update: April 13 2026

You can view the password for the root user in the control panel: in the top menu, click Products → Dedicated Servers → Servers → Server page → Operating System tab . The password is available for viewing 24 hours from the start of installation and reinstallation of the OS or configuration changes.

If you forget or lose your password, you can recover it through the recovery and diagnostic modes:

• for Linux and Windows servers - recover the server password in Rescue;
• for Windows servers - recover server password in WinPE.

For macOS servers, you cannot recover your password. To continue using the server, create a ticket.

Restore server password in Rescue

Ubuntu and Debian

1. Boot the server in Rescue recovery and diagnostic mode.

2. Connect to the server in Rescue mode via KVM console or SSH.

3. Mount the OS file system.

4. Change the password for the root user:

   passwd root

5. Enter the new password twice. The password will not be displayed on the command line.

6. Wait for a response that the password has been changed:

   passwd: password updated successfully

7. If the mount was done manually via the mount command, synchronize the data:

   sync

8. Get out of the environment:

   exit

9. If mounted manually via the mount command, unmount the file system:

   umount /dev/<partition> /mnt

   Specify <partition> is the partition on the disk to which you mounted the file system in step 3..

10. Revert to the previous server boot pattern or reboot the server from the OS. When you reboot the server from the OS, the boot template will automatically change to the one that was set before the server boot template was changed. the server boot pattern was set before the server boot pattern was changed.

CentOS

1. Boot the server in Rescue recovery and diagnostic mode.

2. Connect to the server in Rescue mode via KVM console or SSH.

3. Mount the OS file system.

4. Change the password for the root user:

   passwd root

5. Enter the new password twice. The password will not be displayed on the command line.

6. Update the password checksums:

   touch /.autorelabel

7. If the mount was done manually via the mount command, synchronize the data:

   sync

8. Exit the environment. The partition will be automatically unmounted:

   exit

9. Revert to the previous server boot pattern or reboot the server from the OS. When you reboot the server from the OS, the boot template will automatically change to the one that was set before the server boot template was changed. the server boot pattern was set before the server boot pattern was changed.

Windows

1. Boot the server in Rescue recovery and diagnostic mode.

2. Connect to the server in Rescue mode via KVM console or SSH.

3. Print information about the partitions on the available disks:

   lsblk

   A list of disks with partitions will appear in the response. For example:

   NAME    MAJ:MIN RM   SIZE RO TYPE MOUNTPOINTS
   sda       8:0    0   2.9G  0 disk
   └─sda1    8:1    0   2.9G  0 part
   sdb       8:16   0   160G  0 disk
   ├─sdb1    8:17   0 159.9G  0 part
   ├─sdb14   8:30   0     4M  0 part
   └─sdb15   8:31   0   106M  0 part

   Here sda1, sdb1, sdb14, sdb15 are partitions on the disk. Partition names may be different in your OS.

4. Select the system partition, usually the largest partition on the disk. In the example in step 2, this is the sdb1 partition.

5. Mount the OS disk partition to the /mnt directory:

   mount -t ntfs-3g /dev/<partition> /mnt

   Specify <partition> is the partition on the disk you selected in step 4..
