I appreciate Googles concerns when it comes to our online security. However, I think we might have a case of unintended consequences.
If you log on to your Google services from a new (or unknown) piece of hardware or from a new place, Google seems to block this attempt — often demanding that you change your password. I can see the logic behind that.
But if this happens often (and for some it does) it will lower the quality of the chosen new password. Having to figure out a new password/phrase (that you can remember) on the go simply doesn’t give you time to consider a strong and impregnable one.
Just sayin’.
