+    \class QNetworkSettingsUserAgent
+    \inmodule QtDeviceUtilities
+
+    \brief The QNetworkSettingsUserAgent represents the user credentials for
+    connecting to a network.
+
+    The QNetworkSettingsService::connectService() method is used to connect to
+    a Wifi network. The network name is specified by using a service set
+    identifier (SSID). If no password is needed, the connection is created
+    immediately. QNetworkSettingsService::state property can be used to
+    monitor the state of the connection.
+
+    If a password is needed, the
+    QNetworkSettingsUserAgent::showUserCredentialsInput() signal is emitted.
+    To create a connection, the password is set by using the
+    QNetworkSettingsUserAgent::setPassphrase() method.
+
+    \sa QNetworkSettingsManager
