Question

是否支持在iOS上启动Google身份验证器？

我想让客户更轻松地打开应用并复制出基于时间的代码，然后再将其粘贴回我的应用中。

我凭经验发现这个（Swift）代码将启动应用程序：

UIApplication.sharedApplication().openURL(NSURL(string: "otpauth://")!)

...但我想知道是否有更好的，受支持的方式。

具体来说，是否支持不带参数的otpauth：//协议来启动应用程序？

Answer 1

查看应用程序的Git仓库，看起来他们已经为机器人otpauth和totp注册了自定义URL方案

在这里

以下是有关如何构建网址的文档：

正确构建并在同一设备上获取您的应用和Google身份验证器应用后，您只需要进行测试。
