Google added a new password recovery option that let you “associate a mobile phone number with your Google Account and Google will send a recovery code by SMS”. To set up password recovery via your mobile phone, just sign in to your account and click Change Password Recovery Options. Enter your mobile phone number and current password and then click Save. For now, the options is available in US only, so you need to use a US proxy to see it. Google also updated the password recovery settings page to include all the account-recovery options: secondary email addresses, text messages and the security question.
