In case an attacker forces you to reveal the password, VeraCrypt provides plausible deniability. In contrast to file encryption, data encryption performed by VeraCrypt is real-time (on-the-fly), automatic, transparent, needs very little memory, and does not involve temporary unencrypted files."/> <meta name="keywords" content="encryption, security"/> <link href="styles.css" rel="stylesheet" type="text/css" /> </head> <body> <div> <a href="Documentation.html"><img src="VeraCrypt128x128.png" alt="VeraCrypt"/></a> </div> <div id="menu"> <ul> <li><a href="Home.html">Home</a></li> <li><a href="/code/">Source Code</a></li> <li><a href="Downloads.html">Downloads</a></li> <li><a class="active" href="Documentation.html">Documentation</a></li> <li><a href="Donation.html">Donate</a></li> <li><a href="https://sourceforge.net/p/veracrypt/discussion/" target="_blank">Forums</a></li> </ul> </div> <div> <p> <a href="Documentation.html">Documentation</a> <img src="arrow_right.gif" alt=">>" style="margin-top: 5px"> <a href="Security%20Requirements%20and%20Precautions.html">Security Requirements and Precautions</a> <img src="arrow_right.gif" alt=">>" style="margin-top: 5px"> <a href="Multi-User%20Environment.html">Multi-User Environment</a> </p></div> <div class="wikidoc"> <div> <h1>Multi-User Environment</h1> <p>Keep in mind, that the content of a mounted VeraCrypt volume is visible (accessible) to all logged on users. NTFS file/folder permissions can be set to prevent this, unless the volume is mounted as removable medium (see section <a href="Removable%20Medium%20Volume.html"> <em>Volume Mounted as Removable Medium</em></a>) under a desktop edition of Windows Vista or later (sectors of a volume mounted as removable medium may be accessible at the volume level to users without administrator privileges, regardless of whether it is accessible to them at the file-system level).<br> <br> Moreover, on Windows, the password cache is shared by all logged on users (for more information, please see the section <em>Settings -> Preferences</em>, subsection <em>Cache passwords in driver memory</em>).<br> <br> Also note that switching users in Windows XP or later (<em>Fast User Switching</em> functionality) does <em>not</em> dismount a successfully mounted VeraCrypt volume (unlike system restart, which dismounts all mounted VeraCrypt volumes).<br> <br> On Windows 2000, the container file permissions are ignored when a file-hosted VeraCrypt volume is to be mounted. On all supported versions of Windows, users without administrator privileges can mount any partition/device-hosted VeraCrypt volume (provided that they supply the correct password and/or keyfiles). A user without administrator privileges can dismount only volumes that he or she mounted. However, this does not apply to system favorite volumes unless you enable the option (disabled by default) <em>Settings</em> > ‘<em>System Favorite Volumes</em>’ > ‘<em>Allow only administrators to view and dismount system favorite volumes in VeraCrypt</em>’.</p> </div> </div><div class="ClearBoth"></div></body></html>
