Following Twitter’s recent announcement, LinkedIn has just launched their own two-step verification feature.

“At LinkedIn, we are constantly looking for ways to improve the security of our members’ accounts. All LinkedIn accounts are already protected by a series of automatic checks that are designed to thwart unauthorized sign-in attempts. Now, we are introducing a new optional feature that adds another layer of security to your LinkedIn sign-in: two-step verification.

Most internet accounts that become compromised are illegitimately accessed from a new or unknown computer (or device). Two-step verification helps address this problem by requiring you to type a numeric code when logging in from an unrecognized device for the first time. This code will be sent to your phone via SMS. When enabled, two-step verification makes it more difficult for unauthorized users to access your account, requiring them to have both your password and access to your mobile phone,” says LinkedIn’s Vicente Silveira.

If you wish to turn on LinkedIn’s two-step verification, just go to your settings and click on the “Account” tab. From there, click on “Manage security settings.” You’ll see an option to turn it on there.

Two-step verification, while far from perfect, adds an extra layer to your account security. It’s becoming a popular option for companies like Google, Apple, Twitter, and now, LinkedIn.
