# 一次性分享密码

通过链接分享密码，密码只显示一次，随后链接自动销毁。

无需账号。Free 套餐永久免费。

## 工作原理

1. 01
   ### 粘贴密码、密钥或文件
   内容在发送之前先在您的浏览器中加密。所有匿名创建的机密信息都开启阅后即焚。
2. 02
   ### 发送链接
   只需一个网址。# 之后的密钥留在浏览器中，不会到达我们的服务器。
3. 03
   ### 存储的机密信息已销毁
   第一次打开就会销毁密文。之后无论谁再访问，看到的都是内容已销毁的提示。

浏览器端加密于 2026 年 9 月 29 日上线。在此之前创建的机密信息以明文形式存储，直到过期为止。文件的名称、大小和类型目前对我们仍然可见。 阅读完整的安全模型 (https://uselinkpilot.com/security-architecture).

## 这里说的一次性分享密码是什么意思

本页讲的是把密码只分享一次，而不是身份验证器应用生成的六位数验证码。您手上有一组凭据，另一个人需要它，而您不希望交接之后留下任何副本。上方的表单生成的链接正是这样：收件人打开链接、看到密码，存储的密文在同一步中即被覆盖。

## 密码一次性分享的原理

您的浏览器用 AES-GCM-256 加密文本，并把密钥保存在链接中 # 之后的部分。服务器收到的只是密文和一个随机后缀。收件人打开链接时，单纯加载页面只会检查状态；点击“查看”才会返回密文，并把机密信息标记为已销毁。这两步是原子操作，所以两个人同时打开链接，也不可能都读到内容。对方的浏览器用链接中的密钥解密文本。

之后无论谁再访问，看到的都是内容已销毁的提示，HTTP 状态码为 410，告诉浏览器和缓存这条内容已永久消失。

## 一次性分享密码并设置有效期

匿名创建的链接如果没人打开，七天后过期。使用免费账号时，可以选择一小时、24 小时或七天，并在仪表盘中撤销链接。Pro (https://uselinkpilot.com/pricing) 套餐还提供口令、自定义过期日期和时间以及审计时间线。这样，只分享了一次的凭据，您也能证明它只被打开过一次。

## 常见问题

### 这和身份验证器生成的一次性密码（OTP）是一回事吗？

### 如果两个人同时打开链接会怎样？

### 一次性链接可以重复使用吗？

### 一次性分享密码需要账号吗？

Pro 套餐每月 $29，可为每条机密信息设置口令、自定义过期日期和时间，并提供审计时间线，记录每一次查看、销毁和撤销。 查看套餐 (https://uselinkpilot.com/pricing).
