As we all might know that today is "Safe Internet Day". So Google is reminding us for the security check-up. I tried it. And I saw that I could remove my security question. I did it with the belief that I will add a better question (I forgot the answer of the earlier question anyway).
But when I tried it then I found that there is no option to add a new security question. I believe that the security question is necessary. Here is a picture how Recovery options looks like for me.
There should be something with the name called 'Security Question' below 'Recovery phone'. Is there a way by which I can add that question? When I removed it I even got a mail from Google. By clicking that link I was directly forwarded to 'My last device activity', which is definitely not helpful in adding the question again.
