In its latest move to improve the security of its users' accounts, LinkedIn social network for professionals introduced an optional service called two-factor authentication on Friday.
LinkedIn's announcement of the two-factor authentication service comes nearly a week after a similar service was introduced by popular microblogging site Twitter following a series of high-profile cyber-attacks on its users.
The two-factor authentication service introduced by LinkedIn has been designed for the verification of the identity of users when they log in to the social network, by requiring them to enter a numeric code which will be sent to them via a text message.
When the two-factor authentication option is switched on by the LinkedIn users, they can log in with an unrecognized-by-LinkedIn device only after they enter a verification code which they receive through SMS.
Two-step authentication is deemed a tighter security measure, which has been put in place by some of the leading websites - like Facebook, Google and Microsoft - for quite some time now.
The use of two-step authentication by websites is recommended by security experts chiefly because of the reason that the process requires the person accessing a user account to have both the password as well as a mobile device on hand.
