Professional social-networking site LinkedIn on Friday 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.
If you have a LinkedIn account, you can Turn on Two-step verification for
now by going to Settings, selecting the Account tab and clicking Manage
security settings option.
The news come one week after Twitter introduced two-factor authentication
following a series of recent hacks targeting high-profile businesses on
the blogging site. Apple, Facebook and Google also offer two-step
authentication as an option for users.
