Does not require Admin rights to open encrypted disk.

Encrypted Rohos Disk BrowserThe new version of Rohos Disk (1.18) includes new utility, Rohos Disk Browser. This enables you to open and view the contents of secret partitions on a USB drive on any other computer, even if you do not have administrative rights.

Rohos Disk can password-protect a portion of a USB flash drive, by creating a virtual encrypted partition. The partition is protected by a password, and can be opened on any computer. Now, even if you are in an internet cafe and have no administrative rights, you can still have read access to your secret partition with the help of the Rohos Disk Browser utility. This means that you can open any file and read any data. Naturally when you are at your home or office computer, you will still be able to work with your encrypted partition as usual.

On a strange computer you can always open your protected partition on the USB flash drive (in read-only mode) with the help of the Rohos Disk Browser utility. This makes it possible to open or copy only one particular file or directory, without granting access to every file.

This feature is enabled in a Rohos Mini Drive program – FREE and tiny USB drive encryption tool.

How Rohos Logon Key works in Safe Mode

Rohos Logon Key is the only authentication software that protects Windows XP/Seven login even in Safe Mode. This allows user to use USB key for any Windows startup mode and offer additional security. The user often ask us whether it’s possible to bypass Rohos login by starting Windows using Safe Mode bootup? No.

“The user account security and the computer security in a whole will be imperfect, if a user could load PC in Safe Mode, and log in by usual password avoiding the USB Key.”

Rohos protects your computer even in Safe Mode. This is a unique feature. All of our competitors just recommend you to disable Safe Mode via Windows registry…

Here is how Rohos Logon protects your PC in Safe Mode (see the picture below):

  • Rohos adds USB Key icon in the login window when loading into Safe Mode
  • For Windows XP and Vista – user name/password input fields are disabled (optionally)
  • Login can be performed by using USB Key (or regular password if it is enabled, or Rohos emergency login).

Rohos blocks Windows Safe Mode bootup

Please note: Safe Mode is available in Windows XP – Seven. It loads the system into “clean” state – at the same time all 3rd party authentiation modules (GINA or Authentication Providers) are being turned off, many drivers and all the programs from startup are disabled.

NB: Most of the authentication solutions are disabled in Safe Mode. Instead they suggest users to disable Safe Mode possibility via Windows registry. Thus, in case there are problems, it will be very difficult to restore Windows.

How Rohos Logon Key works in Safe Mode:

  1. Rohos Logon Key register a simple service (ntserv.exe) in Windows Registry
  2. Upon Safe Mode load, NTserv.exe starts. It detects active Windows login screen and run Rohos logon key icon on it.
  3. Rohos Logon Key icon allows you to login by USB Key. Depending on the Rohos security setting, regular ‘password based’ login can be disabled by disabling pasword input fields.

Pulling USB drive out of the computer with Rohos Logon…

We always wanted to tell you that in order to use the program Rohos Logon Key, you have to set up the option “Optimize USB drive for quick removal” (read farther).
And our user Patrick reminded us about that:

“I am trying Rohos Logon Key . I have two questions. If you pull USB drives out of the computer, you risk losing data or killing the drive. Couldn\’t this cause a problem if using Rohos in this manner? …”

Patrick meant that before pulling the USB drive out you should use the dialog Safe hardaware removal:

Safe USB drive removal dialog.

But when you use Rohos Logon Key it’s useless to use this Safe Removal dialog (though you may do it if you use PIN code and lock the system by hotkey Win+L), because the quick computer lock-out by using USB key becomes senseless. In this case in Windows you should set up the option To optimize USB drive for quick removal:

Optimize USB flash drive for quick removal to prevent data loss

The red lines show the actions that go one after another: My computerUSB disk properties – Hardware page – double click on the name of the USB diskPolicyOptimize USB drive for quick removal check box.

More than 20 USB flash drives were at our disposal, and only 1 of 3 “has died” suddenly (stopped recognized by Windows on the next day).
