On the heels of Twitter, Evernote and practically every other Silicon Valley-based Internet company, LinkedIn has announced its adoption of two-step verification.
The business-geared social network claimed on Friday that accounts are already protected via a series of "automatic checks that are designed to thwart unauthorised sign-in attempts", but it still introduced two-step verification as an optional feature.
"Most internet accounts that become compromised are illegitimately accessed from a new or unknown computer (or device)," said LinkedIn. "Two-step verification helps address this problem by requiring you to type a numeric code when logging in from an unrecognised device for the first time."
LinkedIn will send the numeric codes to users via SMS, requiring them to have both a password and access to their mobile phone before logging in. To activate two-step, go to Settings, select the Account tab, and click Manage security settings option.
The social network provided more detailed step-by-step instructions in a slideshow on its blog.
