Recovering password using USB flash-drive for Kerio Operator

Kerio Technologies provides a tool for password recovery. The tool is designed for use from a USB flash-drive.

For password recovery a USB flash-drive with capacity of at least 256 MB will do.

The password recovery tool is designed for a single use to avoid unexpected repetition of the operation upon the next restart in case that the flash-drive has not been dismounted. This implies that once you perform the operation, the disk content cannot be used again and the files can be removed.

Creating and using a password recovery tool

Forgotten administration password can be recovered by using file kerio-operator-password-reset.

Follow these instructions:

  1. Mount the USB flash-drive to your computer.
  2. Make sure that only one fragment with file system FAT16 or FAT32 (VFAT) is created on the flash-drive. The USB disk must not be formatted by file system NTFS or ext2 / ext3 / ext4.
  3. Save file kerio-operator-password-reset to the flash-drive.
  4. Switch off the Kerio Operator.
  5. Plug the USB flash-drive into the USB port.
  6. Switch on Kerio Operator.
  7. In your web browser, open the Kerio Operator Administration.
  8. Activation wizard opens in the browser. As the product has already been activated, the wizard will require a new administration password.

Now you can login as user Admin with a new password.


If it does not work, try another USB flash-drive.
