in is usually used to enter a specific page, website or application, which trespassers cannot see. </p><p>Once the user is logged in, the login token may be used to track what actions the user has taken while connected to the site. </p><p>Logging out may be performed when the <a href="/wiki/User_(computing)" title="User (computing)">user</a> takes an action, such as entering an appropriate <a href="/wiki/Command_(computing)" title="Command (computing)">command</a> or clicking on an external link. It can also be done implicitly, such as by the user powering off their workstation, closing a <a href="/wiki/Web_browser" title="Web browser">web browser</a> window, leaving a website, or not refreshing a website within a defined period. </p><p>A login page may have a return <a href="/wiki/URL_redirection" title="URL redirection">URL</a> parameter, which specifies where to redirect back after logging in or out. For example, it is <code>returnto=</code> on this site. </p><p>In the case of websites that use <a href="/wiki/HTTP_cookie" title="HTTP cookie">cookies</a> to track sessions, when the user logs out, session-only cookies from that site will usually be deleted from the user's computer. In addition, the server invalidates any associations with the session, thereby making any session-handle in the user's cookie store useless. </p><p>This feature comes in handy if the user is using a <a href="/wiki/Public_computer" title="Public computer">public computer</a> or a computer that is using a <a href="/wiki/Wi-Fi_hotspot" title="Wi-Fi hotspot">public wireless connection</a>. As a security precaution, one should not rely on implicit means of logging out of a system, especially not on a public computer; instead, one should explicitly log out and wait for confirmation that this request has taken place. </p><p>Logging out of a computer, when leaving it, is a common security practice preventing unauthorized users from <a href="/wiki/Tampering_with_evidence" title="Tampering with evidence">tampering</a> with it. Some people choose to have a password-protected <a href="/wiki/Screensaver" title="Screensaver">screensaver</a> set to activate after some period of inactivity, thereby requiring the user to re-enter their login credentials to unlock the screensaver and gain access to the system. </p><p><b>Methods of Logging In</b> </p><p>They include: </p> <ul><li>Image recognition</li> <li>Fingerprints scanning</li> <li><a href="/wiki/Iris_recognition" title="Iris recognition">eye scan</a></li> <li>passwords (oral or textual input)</li></ul> <div class="mw-heading mw-heading2"><h2 id="History_and_etymology">History and etymology</h2></div> <figure class="mw-default-size" typeof="mw:File/Thumb"><a href="/wiki/File:IBM_AIX_4_Login_Prompt.jpeg" class="mw-file-description"><img src="//upload.wikimedia.org/wikipedia/commons/thumb/f/f0/IBM_AIX_4_Login_Prompt.jpeg/220px-IBM_AIX_4_Login_Prompt.jpeg" decoding="async" width="220" height="164" class="mw-file-element" srcset="//upload.wikimedia.org/wikipedia/commons/thumb/f/f0/IBM_AIX_4_Login_Prompt.jpeg/330px-IBM_AIX_4_Login_Prompt.jpeg 1.5x, //upload.wikimedia.org/wikipedia/commons/thumb/f/f0/IBM_AIX_4_Login_Prompt.jpeg/440px-IBM_AIX_4_Login_Prompt.jpeg 2x" data-file-width="2592" data-file-height="1936" /></a><figcaption><a href="/wiki/IBM_AIX" title="IBM AIX">IBM AIX</a> Version 4 console login prompt.</figcaption></figure> <p>The terms "login" and "logon" became common with the <a href="/wiki/Time_sharing" class="mw-redirect" title="Time sharing">time sharing</a> systems of the 1960s and <a href="/wiki/Bulletin_Board_System" class="mw-redirect" title="Bulletin Board System">Bulletin Board Systems</a> (BBS) in the 1970s. </p><p>Early <a href="/wiki/Home_computers" class="mw-redirect" title="Home computers">home computers</a> and <a href="/wiki/Personal_computer" title="Personal computer">personal computers</a> did not generally require them until <a href="/wiki/Windows_NT" title="Windows NT">Windows NT</a>, <a href="/wiki/OS/2" title="OS/2">OS/2</a> and <a href="/wiki/Linux" title="Linux">Linux</a> in the 1990s. </p><p>The term <i>login</i> comes from the verb <i>(to) log in</i> and by analogy with the verb <i>to clock in</i>. </p><p>Computer systems keep a <i><a href="/wiki/Logging_(computing)" title="Logging (computing)">log</a></i> of users' access to the system.
