# 一次性分享密碼

用連結分享密碼，密碼只顯示一次，之後連結自動銷毀。

不需要帳號。Free 方案永久免費。

## 運作方式

1. 01
   ### 貼上密碼、金鑰或檔案
   內容在傳出之前就已在瀏覽器中加密。所有匿名機密連結都啟用閱後即焚。
2. 02
   ### 傳送連結
   只有一個網址。# 之後的金鑰留在瀏覽器裡，絕不會傳到我們的伺服器。
3. 03
   ### 儲存的機密內容已不存在
   首次開啟就會銷毀密文。之後任何人再開啟，看到的都是「內容已銷毀」頁面。

瀏覽器端加密於 2026 年 9 月 29 日上線。在此之前建立的機密內容，到期前都以明文儲存；檔案的名稱、大小和類型，我們至今仍看得到。 閱讀完整的安全模型 (https://uselinkpilot.com/security-architecture).

## 這裡說的一次性分享密碼是什麼

本頁講的是只分享一次密碼，不是驗證器應用程式產生的六位數驗證碼。您手上有一組帳號密碼，有人需要用到，而您希望交接完成後不留下任何副本。上方的表單建立的連結正是如此：收件者開啟連結、讀取密碼，儲存的密文在同一步驟中就會被覆寫。

## 一次性分享密碼的運作方式

您的瀏覽器以 AES-GCM-256 加密文字，金鑰保留在連結中 # 之後的部分。伺服器收到的只有密文和一個隨機代碼。收件者開啟連結時，單純載入頁面只會檢查狀態；按下「顯示」才會取回密文並把機密內容標記為已銷毀，而且這是不可分割的單一操作，所以兩個人同時開啟連結，不可能都讀到內容。收件者的瀏覽器再用連結中的金鑰解密文字。

之後任何人再開啟，都會看到「內容已銷毀」頁面，HTTP 狀態碼為 410，告訴瀏覽器和快取這份內容已永久消失。

## 一次性分享密碼，再加上時間限制

未開啟的匿名連結會在七天後到期。使用免費帳號時，可以選擇一小時、24 小時或七天，也能從儀表板撤銷連結。Pro (https://uselinkpilot.com/pricing) 方案再加上通關密語、自訂到期日期和時間，以及稽核時間軸，讓您能證明只分享一次的帳號密碼確實只開啟過一次。

## 常見問題

### 這和驗證器產生的一次性密碼（OTP）一樣嗎？

### 如果兩個人同時開啟連結會怎樣？

### 一次性連結可以重複使用嗎？

### 一次性分享密碼需要帳號嗎？

Pro 方案每月 $29 美元，每則機密內容都能加上通關密語，可自訂到期日期和時間，並提供稽核時間軸，記錄每次檢視、銷毀和撤銷。 查看方案 (https://uselinkpilot.com/pricing).
