I don't enable 2-step verification on my gmail, but it's registered on my phone. now, I want login to this gmail account, require tap "yes" and tap "number"(for example 42 or 26 ). Now, I want know that does this happened to every one??? does Google have increased the security level of their accounts???

If Gmail is not 2step verification and registered on the phone, Require tap "yes /Number " when logging in?
