<p>An administrator may need to retrieve a user's password. The command node for this use case SHOULD be "http://jabber.org/protocol/admin#get-user-password".</p> <p>Up to and including revision 1.2 of this XEP, this section defined a command that could be used to retrieve a user's password. This implies that the implementation stores plaintext passwords, a practise that is a well-documented vulnerability<note>OWASP: Password Plaintext Storage &lt;<link url='https://owasp.org/www-community/vulnerabilities/Password_Plaintext_Storage'>https://owasp.org/www-community/vulnerabilities/Password_Plaintext_Storage</link>&gt;</note>. This command has therefore been retracted from this XEP. To retain section numbering, this text replaces the command definition that previously existed in this section.</p>
<p>A sample protocol flow for this use case is shown below.</p>
<example caption='Admin Requests to Get a User&apos;s Password'><![CDATA[

action='execute'
node='http://jabber.org/protocol/admin#get-user-password'/>
</iq>
]]></example>
<p>Unless an error occurs (see the <link url='#errors'>Error Handling</link> section below), the service SHOULD return the appropriate form.</p>
