LinkedIn has introduced 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.
Here is how you do it:
Turn on Two-step verification for your account now by going to Settings (or Privacy & Settings), selecting the Account tab and clicking Manage Security settings option. Turn on the Two-step verification for sign-in and you will be walked through the process.
