The optional service, known as two-factor authentication, is designed to verify the identity of users as they log in by requiring them to enter numeric codes sent via text message. LinkedIn introduced the service almost a year after a highly publicized breach that exposed passwords of millions of its users. Some security experts criticized LinkedIn at the time, saying the firm had failed to use best practices to secure its passwords. Also read click here. The site provided instructions to its 225 million users on how to turn on the optional service on the company's official blog. As per the blogpost, posted by one of LinkedIn's directors Vicente Silveria, all user accounts "are already protected by a series of automatic checks that are designed to thwart unauthorized sign-in attempts."
