LinkedIn adds two-factor authentication through SMS
Who knew that tighter security was all the rage these days? Following Dropbox, Google and virtually everyone else, LinkedIn has joined the trendy (if smart) ranks of those offering two-factor authentication as an option. Switch it on and you'll have to enter a verification code delivered by SMS before you can log in with a device that LinkedIn doesn't recognize. That's all there is to the process, really, but it may be enough to prevent ne'er-do-wells from messing with your CV.
