# 阅后即焚便签

写下便签，分享链接，便签读过一次后即销毁。

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).

## 三个步骤创建一次性便签

在上方写好便签，然后点击按钮。文本在您的浏览器中用 AES-GCM-256 加密，密钥保存在链接中 # 之后的部分，因此 LinkPilot 只存储密文。链接可以用任何方式发送。对方打开链接，点击“查看”，读到便签，存储的副本也在这次查看中销毁。

## 适合日常交接的阅后即焚便签

只需读一次、不该留存的内容都适合用这种便签：给帮忙看家的人的报警器密码、礼品卡卡号、客户的临时登录凭据，或者您不希望被转发的说明。对方只需要一个浏览器。未读的便签七天后过期；有了免费账号，可以把有效期缩短为一小时或 24 小时，还能在对方阅读前撤销便签。

## 与 Privnote 的比较

Privnote 是最知名的阅后即焚便签工具，同样在浏览器中加密。LinkPilot 增加了在仪表盘中撤销、文件附件，以及 Pro (https://uselinkpilot.com/pricing) 套餐中的口令和审计时间线，而且这些都和您的短链接在同一个工作区里。Privnote 替代品 (https://uselinkpilot.com/zh/privnote-alternative)页面列出了两者的差异，也说明了什么情况下 Privnote 更合适。

## 常见问题

### 阅读阅后即焚便签需要账号吗？

### 如果我自己打开便签检查一下呢？

### 可以给便签设密码吗？

### 便签最长可以写多少？

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).
