2FA: A modern essential!

Next story


Two-factor authentication is an easy win for your online account security and here’s why.

As we recently explained in our blog about password managers having unique passwords for all of your online accounts isn’t such a difficult task, but how can you add extra security on top of that?

Even with unique passwords and a password manager, your accounts could still be accessed by malicious individuals through no fault of your own: your login information could be stolen directly from the website itself.

Two-factor authentication (2FA), sometimes called multi-factor authentication, is a simple and cheap (often free) way of increasing the security of your online accounts.

2FA generally uses one of three methods, a physical token, an SMS, or an app, to generate a code which you’ll be asked to enter when you try to login.

Mark James, ESET IT Security Specialist, explains the merits of using two-factor authentication with as many websites and accounts as possible.

“One of the ways of adding an extra layer of security to your normal logins is by using multi or two factor authentication.

“This takes something you know (your username and password or pin) and something you have (a phone or hard token device) this enables you to generate a code that is entered after you use your username and password.

“This code is unique in the fact that it is only useable once or becomes invalid if not used within a specific timeframe.

“That way even if someone does obtain your username and password they are unable to guess the random generated code and unable to access your account, giving you time to change your compromised password.”
