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.
Turn on Two-step verification for your account now by going to Settings, selecting the Account tab and clicking Manage security settings option. Step-by-step instructions below:
