Too many steps to use phone as second authentication factor

Pros: can use iPhone’s security chip as authentication hardware key
Cons: I have to open my gmail app, tap the yes button and then type in my iPhone lock key.
Why can’t they simply tap into iPhone’s Face ID to skip all these steps? I might as well type in my google password to login. Yes, it’s more secure. But it does not save me the trouble of having to type in password (in this case my iPhone lock key).

From Zero to Hero

My previous rating was as low you could get and given how many Google projects hit the skids or vanish away, I was shocked that Google did a 180 to drastic improvement. Not only did they completely re-work the smart lock app but they improved the advanced protection program at the same time. Whereas the app was mostly an unreliable fail before, it’s now works like a charm and it allows your iPhone to be one of your security keys. So between my iPhone and the two Titan security keys, my security profile is greatly increased while minimizing the risk of getting locked out - would have to lose both keys and the iPhone. Also, the iPhone as a key allows you additional capabilities that the USB keys can’t provide. So hats off to Google for making the advanced protection a practical high security option as opposed to a self-imposed shackling.

Blocked Security Feature

I’ve enabled this 2-step verification from Google after purchased Google one subscription to ensure it will be more secured. But, the smart lock has stopped working today to verify my login request from other device so I had to log off from this smart lock app since I cannot login to “Google Account” page to disable this feature.

Once I log off from this Smart Lock, then it doesn’t allow me to login again stating that you have enabled “Advanced Protection” turned on so you can’t sign in right now. Well, this is that stupid app suppose to protect my access if log off from this application how else am I suppose to login and authenticate.

It’s a classic dead lock error which google doesn’t fix it and they sent an email about someone from google support will contact in 3-5 business days.

This is atrocious! Why the heck we should purchase a “Google One” and lock our own accounts just because this app doesn’t work in iOS.
