Two-fac­tor au­then­ti­ca­tion (2FA for short) is a pro­tec­tive mea­sure de­signed to en­sure your Ap­ple ID can only be ac­cessed with your ex­plicit ap­proval. With the fea­ture en­abled, you’ll need more than just your email ad­dress and pass­word to sign in to apps and ser­vices us­ing your Ap­ple ID.

In ad­di­tion to those cre­den­tials, you’ll need to have a trusted de­vice to hand in or­der to re­ceive a ver­i­fi­ca­tion code, which is used to con­firm that the sign-in re­quest came from you. If who­ever is sign­ing in doesn’t have one of your trusted de­vices to hand — and un­locked — they’ll be un­able to read the code and pre­tend they are you.

2FA re­quires that you reg­is­ter at least one trusted phone num­ber to re­ceive ver­i­fi­ca­tion codes, which can be given as a text mes­sage or in an au­to­mated phone call. You might also add a num­ber be­long­ing to your part­ner or a close fam­ily mem­ber; as long as that per­son doesn’t also know your pass­word, they’ll be un­able to ac­cess your ac­count.

If you haven’t got ac­cess to any of your trusted de­vices, you can en­ter your Ap­ple ID’s email ad­dress and pass­word to sign in on a tem­po­rary or re­place­ment de­vice, then ask your trusted friend to pro­vide you with the code they re­ceive on their phone num­ber when you at­tempt to sign in.

TRUSTED DE­VICES

The down­side of need­ing one of your trusted de­vices, or be­ing able to reach a trusted con­tact, is a small price to pay for the re­as­sur­ance that even if a po­ten­tial in­truder knows your Ap­ple ID’s pass­word, they can’t ac­cess your ac­count — and that you’ll be in­formed about any at­tempt to break in.

Ad­di­tion­ally, 2FA sim­pli­fies ac­cess to some iCloud fea­tures — no­tably iCloud Key­chain, which will no longer re­quire you to set and re­mem­ber a sep­a­rate se­cu­rity code to ver­ify at­tempts to use your key­chain; in­stead, you’ll be alerted to the at­tempt on your trusted de­vices, from which you can sim­ply choose to al­low or pre­vent ac­cess.

Af­ter you con­nect a Mac or iOS de­vice to your iCloud ac­count and ver­ify your iden­tity us­ing 2FA, Ap­ple treats that de­vice as one that’s trusted, and in fu­ture, it’ll re­ceive alerts and ver­i­fi­ca­tion codes.

In or­der for 2FA to be ef­fec­tive, en­sure that your de­vices use a strong pass­word and that no­body else knows it; en­able other sim­ple se­cu­rity mea­sures, such as au­to­mat­i­cally lock­ing af­ter a short time; and keep your Ap­ple ID’s list of trusted phone num­bers up to date at ap­pleid.ap­ple.com.
