 ## Usage - Direct socket
 
     const { HttpsProxySocket } = require('@journeyapps/https-proxy-socket');
-    const proxy = new HttpsProxySocket('https://my-proxy.test', {
-        auth: 'myuser:mypassword' // Optional: proxy basic auth
-    });
+    const proxy = new HttpsProxySocket('https://my-proxy.test');
 
     const socket = await proxy.connect({host: 'myhost.test', port: 1234});
