<p>Registering the "not found" handler is a different way than ESP8266WebServer. The <em>onNotFound</em> of ESP8266WebServer does not work with AutoConnect. AutoConnect overrides <em>ESP8266WebServer::onNotFound</em> to handle a captive portal. To register "not found" handler, use <a href="../api/index.html#onnotfound"><em>AutoConnect::onNotFound</em></a>.</p>
<h3 id="auto-save-credential"><i class="fa fa-caret-right"></i> Auto save Credential<a class="headerlink" href="#auto-save-credential" title="Permanent link">&para;</a></h3>
<p>By default, AutoConnect saves the credentials of the established connection in EEPROM. You can disable it with the <a href="../api/index.html#autosave"><strong>autoSave</strong></a> parameter specified by <a href="../api/index.html#autoconnectconfig"><strong>AutoConnectConfig</strong></a>.</p>

<p>The captive portal will only be activated if the first <em>WiFi::begin</em> fails. Sketch can detect with the <a href="../api/index.html#ondetect"><em>AutoConnect::onDetect</em></a> function that the captive portal has started. For example, the sketch can be written like as follows that turns on the LED at the start captive portal.</p>
