These days, iPhone App Development is a great concern for keeping the user data not secured by the hackers and intruders that try to enter the system by finding flaws and loopholes.
Apple is constantly trying to enhance its iPhone app development by releasing new updates frequently so that the confidential data of the user doesn’t go to the public.
It does give them the access to the required applications outside of the Apple app store but it also brings the risk of exposing the iPhone device to the malware and viruses that can completely damage the stored information.
Two-Factor Authentication alerts you when some unknown person tries to log in to any device by entering your Apple id account details.
This will send a notification of alerting you by giving you an option either to deny or to accept the request.
This security feature developed for the iPhone app development and other Apple devices protects our information from getting into wrong hands.
