适用于 Windows 和 MacOS 以及 Linux 的 Authy Desktop，将于 2024 年 3 月 19 日达到生命周期终点 (EOL) 官方公告。
这意味着 Authy 将彻底放弃开发基于 Electron 的跨平台客户端，我们将不再能够使用 Authy Desktop 方便地与移动端同步和查看 TOTP 密钥。
此情此景不得不引用一句名言：|| 和 Electron 这群虫豸在一起，怎么能搞好 Desktop 呢？不能再犹豫了，一定要出重拳！ ||
当初选用 Authy Desktop 的原因是因为它可以很轻松地支持跨平台和多设备同步，但现在不得不考虑迁移到其他的 2FA 管理工具。
跑路计划受阻
==当初享受了多少便利，现在就要付出多少代价。==
Authy 官方以 “维护用户的密钥安全” 为由不允许从客户端直接导入或者导出 TOTP 密钥： 原文链接
In order to maintain security for our users, the Authy application does not allow importing or exporting 2FA account tokens.
另辟蹊径
虽然 Authy 官方不允许直接导出 TOTP 密钥，但是我们可以用比较 dirty 的方法来实现这个目的：

- 成功导出 TOTP 密钥，跑路成功
教程开始
WARNING
以下操作需要一定计算机操作技能，并且可能违反 Authy 的使用协议，仅供研究用途，请勿用于非法用途。
|| 不过都到跑路这一步了，你说法制我都觉得好笑.jpg ||
安装旧版 Authy Desktop 2.2.3
INFO
以下操作需要使用到 Authy Desktop 的旧版本，如果你已经升级到了最新版本，可以先卸载当前版本，然后安装旧版本。
- 安装旧版 Authy Desktop，最后支持远程调试的版本为
2.2.3。
可以通过以下链接下载旧版 Authy Desktop：
32位 安装程序 MD5：d66d63abb482523ad27dfe676e249fff 64位 安装程序 MD5：efd176d89b280809b9f84fda9ba50840
Win + R 输入 %LOCALAPPDATA%\authy 回车后来到 Authy 的安装目录，删除 Update.exe 文件。
随后再安装旧版 Authy Desktop，安装完成后关闭自动打开的 Authy Desktop 窗口，继续下面的操作。
步骤 1：注入调试参数
在启动 Authy Desktop 时，我们可以通过追加命令行参数 --remote-debugging-port 以启用调试模式：
- Win + R 打开运行窗口，输入
powershell或者cmd打开命令行
powershell
# Windows PowerShell 命令行
Start-Process -FilePath "$env:LOCALAPPDATA\authy\app-2.2.3\Authy Desktop.exe" -ArgumentList "--remote-debugging-port=9222"batch
:: Windows CMD 命令行
start "" "%LOCALAPPDATA%\authy\app-2.2.3\Authy Desktop.exe" --remote-debugging-port=9222这里将调试端口设置为了 9222，你也可以使用其他端口，不影响后续操作。
步骤 2：进入 Authy 调试页面
打开浏览器，访问 http://localhost:9222，你将看到类似下面的页面：
点击第一个 Twilio Authy 超链接，你将看到类似下面的页面：
步骤 3：执行提取脚本
WARNING
当进行到这一步的时候，你可以断开网络连接，因为提取脚本将会输出所有的 TOTP 密钥，这可能会导致泄露。 记得输入 master password 解密 TOTP 密钥后再断开网络连接。
跟着以下图例打开 DevTools，点击 Sources 选项卡，随后点击 Snippets，新建一个 Snippet，将提取脚本粘贴进去：
提取脚本如下（代码块右上角有复制按钮），您可以根据需要选择不同的提取脚本：
- 可导出为纯文本的最简单的提取脚本：

不出意外的话，你将会看到类似下面的输出：
脚本执行完毕后，会尝试通过 Authy Desktop 主程序 弹窗保存 一个类似 authy-tokens.json 的文件，其中包含了你的 TOTP 密钥信息，请妥善保存。
您可以使用这个文件来导入到其他密码管理器中，或者直接使用其中的信息来配置你的 TOTP 客户端。
