给 GitHub 设置了 Two-factor authentication，添加 fallback SMS number 时发现不支持 +86 号码

[AllenHua]

虽然我近期用 Microsoft Authenticator app 给 GitHub 设置了两步验证，但是最近还是提醒我好几次说要添加更多安全方法，于是我就添加了 Security keys ，在我准备添加手机号接收验证码短信时却在 select 组件中找好久没找到 +86 的号码前缀，ohhhhh ，原来是不支持啊。

为什么不支持？

不支持可能是为用户好

实际上+86 的号码是能收到的(至少我自己的手机号可以)，绕过方法是直接 F12 修改元素

@ClosureEleven #2 同样设置成功了，感谢

以前以为只有自己懒，懒得写后端校验。看来 GitHub 也懒

[neptuno]

话说如果中国接收短信成功率不高，应急的时候接收不到短信，不难受吗

卧槽，还能这么搞！！！

已经接受不到了，应该是修复了吧
