Apple plans additional security features to keep hackers out of user accounts in the face of the recent celebrity photo scandal.
Apple will alert users through email and push notifications when someone tries to change an account password, restore iCloud data to a new device, or when a device logs into an account for the first time, a report in the Wall Street Journal said.
CEO Tim Cook said Apple will broaden its use of the two-factor authentication security system, which requires users to have two of three identifiers such as a password, a separate four-digit one-time code, or a long access key given to the user when they signed up for the service.
Cook said the company plans to more aggressively encourage people to turn on the two-factor authentication options in the new version of iOS, the newspaper reported, following criticism from security experts that Apple could do more to advertise the option.
"The usability battle will always be there but could you ever imagine using your debit card at an ATM and not entering a pin? That's two factor, something you have (a card) & something you know (a pin), and we all get along just fine," WhiteHat Security's Matt Johansen told Reuters.
Apple said on Tuesday the attacks that emerged last weekend were individually targeted on celebrities' iCloud accounts and that none of the cases it investigated had resulted from a breach of its systems.
