But with greater popularity comes greater responsibility and to maintain that popularity Facebook is all set to the strengthen the security of it users. Recent breach at LinkedIn has forced Facebook to take the decision of getting mobile numbers from its users.
Facebook claims that by giving your mobile number, you will be more safe as you will always have a way to reset the password. It is definitely a very good way of resetting password and is employed by most of the top email services in the world like Gmail and Hotmail. But at same time Facebook is know for privacy issues. People are afraid that Facebook will sell their mobile numbers to telemarketers and will harm their privacy.
Facebook has also suggested its user to keep their passwords strong. By strong they mean their passwords should contain number, alphabets and special characters and password should be sufficiently long to be secure.
