Boost your Ap­pleID’s se­cu­rity

Learn how to set up and use two-fac­tor au­then­ti­ca­tion

Mac|Life - - CONTENTS - Kenny Hem­phill

in­tro­duced with iOS 9 and El Cap­i­tan, two-fac­tor au­then­ti­ca­tion (2FA) is a se­cu­rity fea­ture in iCloud. It’s an evo­lu­tion of two-step ver­i­fi­ca­tion, which we’ll re­fer to as 2SV.

The lat­ter pushes a se­cu­rity code to a de­vice us­ing ei­ther SMS or Ap­ple’s Find My iPhone sys­tem; 2FA pushes a no­ti­fi­ca­tion to “trusted de­vices” linked to your ac­count. This tells you that some­one has re­quested a ver­i­fi­ca­tion code and shows you a map of the lo­ca­tion where the re­quest was made.

You can sub­se­quently re­ject the at­tempt to ac­cess your ac­count, or al­low it and have the code sent to the trusted de­vice which you’re us­ing.

In ad­di­tion to at least one trusted de­vice, you’ll also have to reg­is­ter at least one trusted phone num­ber. Ap­ple en­cour­ages you to reg­is­ter more than one, such as your home phone — rather than the iPhone that you’ve con­nected to your iCloud ac­count.

As well as hav­ing Ap­ple send you a code, you can man­u­ally gen­er­ate one your­self from one of your trusted de­vices.
