It was introduced with <a href="/wiki/Mac_OS_8" title="Mac OS 8">Mac OS 8.6</a>, and was included in all subsequent versions of the operating system, as well as in <a href="/wiki/IOS" title="IOS">iOS</a>. A keychain can contain various types of data: <a href="/wiki/Password" title="Password">passwords</a> (for <a href="/wiki/Website" title="Website">websites</a>, <a href="/wiki/File_transfer_protocol" class="mw-redirect" title="File transfer protocol">FTP servers</a>, <a href="/wiki/Secure_shell" class="mw-redirect" title="Secure shell">SSH</a> accounts, <a href="/wiki/Network_share" class="mw-redirect" title="Network share">network shares</a>, <a href="/wiki/Wireless_network" title="Wireless network">wireless networks</a>, <a href="/wiki/Groupware" class="mw-redirect" title="Groupware">groupware applications</a>, <a href="/wiki/Encryption" title="Encryption">encrypted</a> <a href="/wiki/Disk_image" title="Disk image">disk images</a>), <a href="/wiki/Public-key_cryptography" title="Public-key cryptography">private keys</a>, <a href="/wiki/Public_key_certificate" title="Public key certificate">certificates</a>, and secure notes.

Among its many features, PowerTalk used <a href="/wiki/Plug-in_(computing)" title="Plug-in (computing)">plug-ins</a> that allowed mail to be retrieved from a wide variety of mail servers and online services. The keychain concept naturally "fell out" of this code, and was used in PowerTalk to manage all of a user's various login credentials for the various e-mail systems PowerTalk could connect to. </p><p>The passwords were not easily retrievable due to the encryption, yet the simplicity of the interface allowed the user to select a different password for every system without fear of forgetting them, as a single password would open the file and return them all. At the time, implementations of this concept were not available on other platforms. Keychain was one of the few parts of PowerTalk that was obviously useful "on its own", which suggested it should be promoted to become a part of the basic Mac OS. But due to internal politics, it was kept inside the PowerTalk system and, therefore, available to very few Mac users.<sup class="noprint Inline-Template Template-Fact" style="white-space:nowrap;">[<i><a href="/wiki/Wikipedia:Citation_needed" title="Wikipedia:Citation needed"><span title="This claim needs references to reliable sources.

By this point in time the concept was no longer so unusual, but it was still rare to see a keychain system that was not associated with a particular piece of application software, typically a <a href="/wiki/Web_browser" title="Web browser">web browser</a>.

When locked, the password has to be re-entered next time the keychain is accessed, to unlock it.

On a shared Mac/non-Mac network, it is possible for the login keychain's password to lose synchronization if the user's login password is changed from a non-Mac system. Also, if the password is changed from a directory service like Active Directory or Open Directory, or if the password is changed from another admin account e.g. using the System Preferences. Some network administrators react to this by deleting the keychain file on logout, so that a new one will be created next time the user logs in. This means keychain passwords will not be remembered from one session to the next, even if the login password has not been changed. If this happens, the user can restore the keychain file in <code>~/Library/Keychains/</code> from a backup, but doing so will lock the keychain, which will then need to be unlocked at next use. </p> <div class="mw-heading mw-heading2"><h2 id="Third-party_software_for_keychain_synchronization">Third-party software for keychain synchronization</h2><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Keychain_(software)&action=edit&section=5" title="Edit section: Third-party software for keychain synchronization"><span>edit</span></a><span class="mw-editsection-bracket">]</span></span></div> <p>There was a 3rd party software application developed, that enabled synchronization of personal keychains generated using keychain access in <a href="/wiki/MacOS" title="MacOS">Mac OS X</a>, these standard keychain access - generated users keychains could then be synchronised between devices (iPhones - desktop Apple computers), using a pair of keychain synchronization apps developed by Patrick Stein of Jinx Software, one for <a href="/wiki/MacOS" title="MacOS">Mac OS X</a> and another for iOS called Keychain2Go.

The iOS version is simpler because applications that run on mobile devices typically need only very basic Keychain features. For example, features such as ACLs (Access Control Lists) and sharing Keychain items between different apps are not present. Thus, iOS Keychain items are only accessible to the app that created them. </p><p>As Mac users’ default storage for sensitive information, Keychain is a prime target for security attacks. </p><p>In 2019, 18-year-old German security researcher Linus Henze demonstrated his hack, dubbed KeySteal, that grabs passwords from the Keychain. Initially, he withheld details of the hack, demanding Apple set up a bug bounty for macOS. Apple had however not done so when Henze subsequently revealed the hack. It utilized Safari's access to security services, disguised as a utility in macOS that enables IT administrators to manipulate keychains.<sup id="cite_ref-8" class="reference"><a
