Just after Gmail get rid of its beta label introduce a another way to retrieve your forgotten Gmail password via your mobile. It is not a WOW thing but it is pretty much covering all the possible ways to give the maximum to GMail user.
I think Mobile is one of the coolest device you can name. There are more mobile users than any other user base. So any cool product should have options to access and control to the application from a mobile phone.
This is what GMail team has to say out this feature.
"Even the best of us forget our passwords from time to time. In fact, recovering passwords is one of the top reasons people visit the Gmail Help Center. To help with these situations, we recently added the ability to recover your password via text message.
To turn this on for your account, just sign in, select 'Change Password Recovery Options,' enter your cell phone number and click 'Save.'
Next time you forget your password, enter your username on the password-assistance page, and Google will text you a recovery code. No need to check another email account or even leave the page.
In general, it's a good idea to add as many password recovery options to your Google Account as possible, like a secondary email address and security question. And don't forget to keep them up-to-date."
