Apple has greatly expanded the availability of its 2-step verification process for Apple IDs. While it was only available in 11 countries previously, the feature is now available in 59 countries worldwide.
For those not aware, 2-step verification or authentication puts an extra step between entering your ID and password and logging in. It sends a verification message with a code to a preset device or number and only upon entering that code will the person be allowed to log in.
