In May last year, many users in various countries around the world reported having access to the two-step verification security feature of Apple ID. Shortly after, the function disappeared in many countries on the pretext that it had been launched too prematurely …
The only countries officially benefiting from this system so far have been the United States, the United Kingdom, Australia, Ireland and New Zealand (read: Apple ID and iCloud: now 2 verification steps).
However, the function has just reappeared in several new countries, including Canada, the France, Germany, Japan, Italy and Spain. Apple has also updated its support pages for two-step verification. You can set it up at this address.
The two-step verification feature requires users to enter a unique verification code sent to a trusted device in order to access their Apple ID. It was deployed by the Cupertino company in late March just after a major security breach was discovered in account management.
