<p>Here's how to lookup a password in the running secret service,
like gnome-keyring or ksecretservice.</p>
<p>Each stored password has a set of attributes which are
used to lookup the password. If multiple passwords match the
lookup attributes, then the one stored most recently is returned.</p>
<p>These examples use <a class="link" href="py-examples.html#py-schema-example" title="Python example: Define a password schema">the example
schema</a>.</p>
<p>This first example looks up a password asynchronously, and is
appropriate for GUI applications so that the UI does not block.</p>

<table class="listing_frame" border="0" cellpadding="0" cellspacing="0">

<p>This next example looks up a password synchronously. The function
call will block until the lookup completes. So this is appropriate for
non GUI applications.</p>
