Last day when i was logging in to Gmail i observed a new security feature that was introduced by google mail. Its simple, it automatically redirects you to a page which confirms your password recovery alternate email address and phone number.
Google might be receiving a huge number of stolen account requests now-a-days! Its a good way to make sure that your these information are updated, so next time your account is hacked, you are still safe to get it recovered using your mobile number and also your alternate email address. Thank you Gmail ! ( click on the below image to see how)
