Double-locking your things

What is Multi-Factor Authentication?

Most weeks I see posts on social media from other people, claiming their accounts have been hacked.  More than often, it’s not so much a “hack” but more likely, their credentials have been stolen or guessed. 

Hacking is often the least of their problems.

So, assuming it’s someone that I know, I ask them if they’ve changed their password yet.  They usually have.  I ask them for their email address and do a quick check to see if it’s coming up in any known breaches. 

Then I ask them if they’ve enabled MFA (Multi-factor Authentication) on their account.  The almost-inevitible answer is “Whuh?  What is that?”.

This additional pass-code comes often via SMS/Text Message or from an Authenticator application such as Google Authenticator, Microsoft Authenticator or Authy.

Now, ideally, you would protect as many accounts as possible with MFA, but this won’t always be available or be practical.  So, at the very least, ensure that your critical and most important accounts are protected.  These usually include Email, Social Media, on-line Storage such as Dropbox, Box and OneDrive and of course, anything financially related such as online shopping, PayPal and so on.

Whatever service you’re using, the settings for Multi-Factor Authentication (also known as Two-Factor Authentication or 2FA), can usually be found under the settings for your profile, under the heading of “Security”.

If you’re using a service which does not offer MFA / 2FA, perhaps it’s time to move to one that does.
