请问HN：关于谷歌账户验证的思维模型是什么？
我有一个谷歌账户，关联了两个设备，一个是安卓手机，一个是iPhone。启用了双重身份验证，并且我还关联了一个身份验证器。
我想弄清楚我对谷歌账户验证过程的理解是否有误，或者这个过程设计得实在太糟糕了。
--------------------------
第一个问题：在一台之前未访问过谷歌服务的笔记本电脑上访问谷歌服务时，谷歌只向一部手机（属于其他人的安卓手机）发送了“这是你吗”的验证，而没有发送到我的iPhone。我希望也能在我的iPhone上收到通知。
我在iPhone上尝试了以下操作：
a. 重新安装了谷歌应用（谷歌、Gmail）并重新登录，这需要通过安卓手机进行批准。
b. 启用了通知。我在Gmail应用上确实收到过一次通知，但之后就再也没有收到过。
c. 启用了后台应用刷新。
d. 在Wi-Fi和移动数据上设置了通知。电池电量正常（显然，默认情况下在电量低时通知会被禁用）。
------------------------
第二个问题：如何使用身份验证器登录？系统从未询问我。一输入密码，就要求我在安卓手机上点击一个谷歌代码。

I have a google account that has two devices associated with it, one Android and one iPhone. 2FA is enabled, and I have an authenticator associated as well.<p>I would like to find out if I have the mental model of the google account verification process wrong, or it is just horribly engineered.<p>--------------------------
First problem: When accessing a Google service on a laptop that has not accessed that service before, Google sends "Is this you" verification to only one phone (the Android phone that belongs to someone else), not to iPhone (mine). I'd like to get notifications on my iPhone as well.<p>I have tried the following on the iPhone:
a. Re-installed google apps (google, gmail) and logged in again, for which I needed to get it approved by the Android phone.
b. Enabled notifications. I did get a notification once on the gmail app, but never after that.
c. Enabled background app refresh
d. Set notifications on Wifi and cellular. Battery levels are fine (apparently, by default notifications are disabled on low battery level)<p>------------------------
Second issue: How does one log in using an authenticator? It never asks me. As soon as I enter the password, it says to tap a Google code on the Android phone.
