# 什麼是用戶名/密碼身份驗證？它是如何運作的？

您的 711Proxy 用戶名和密碼用於確認是您本人在嘗試訪問我們代理。您可以在儀表板-子賬戶中設置自定義用戶名和密碼。

對於住宅代理，我們使用您在設置代理時選擇的用戶名。用戶名會根據您的代理設置而變化。例如，假設您的用戶名是“username”，如果您想使用來自美國的 IP，會話持續時間爲 5 分鐘，您的用戶名將是“username-zone-custom-region-US-session-(sessionID)-sessTime-5”。

從儀表板獲取憑證後，您可以在您的反檢測瀏覽器、網絡爬蟲、操作系統設置、瀏覽器插件、運動鞋機器人等等工具中使用它們進行身份驗證。
