The world of digital security is a minefield, these days. It is now almost a daily occurrence to see companies either fall victim to (or be fined for) major data breaches. (The list of companies hit makes for some impressive reading!) In fact, there have been over 14 billion data breaches since 2013, and that number is fast increasing, with 75 data records are being stolen every second!

Not all breaches are caused by nefarious hackers. Believe it or not, they only amount for just over 40% of breaches. Other causes making up the remainder include technical glitches or employee error.

We’ve said it before. Passwords should be complicated and changed often. But can you do more? Yes, you can!

What is 2FA?

One snazzy concept that was introduced to thwart login hackers is two factor authentication (2FA). This is where, after you have entered your password, you add a 2nd way to tell the site that you are definitely you! (Like the way, in the movies, that the scientists entering the super-secret spy lab have to use a swipe card and then a retinal scanner to gain entry.) Since you need both to access the account, this extra layer of security seriously increases the protection of sensitive data from these cases of a password database being stolen or hacked.

This second layer can be biometric, like with face detection or fingerprint scanning software, or it can involve sending a one-time-use number code to another device you own, via a text or special app. The latter is probably the most commonly seen and used, at the moment .

Should I use it?

Yes! So many companies are now offering it as an option – Apple, Square, Intuit, Amazon, Google, Facebook, Microsoft, Dropbox, PayPal, GoDaddy…and so on. If a site gives you the option, take it! (Especially anywhere that will have any valuable ID info, financial records or payment details.) You can see who has it and who doesn’t at twofactorauth.org. If you are not sure how to turn on 2FA at those sites, Telesign have set up a website, with tutorials, to show you how!
