Apple iOS 10.3 beta users have been receiving push notifications directing them to enable the two-factor authentication or 2FA for their Apple IDs. Despite the notification, some iPhone users remain doubtful of the upgrade's worthiness.

Most iPhone users have been quite cautious in making any updates or activation when it comes to their mobile's operating system. This attitude towards upgrades has been caused by the reported negative effects of iOS 10.2 and iOS 10.2.1 updates, which undeniably made things worse for iPhone users, in terms of battery life and application usage.

However, the notification being offered by Apple iOS 10.3 is not similar to the previous activations and upgrades being pushed by the mobile OS. Unlike other upgrades in the past, the activation of two-factor authentication (2FA) is meant to increase mobile security, according to Naked Security.

If you have discarded the iOS notification, you may manually enable 2FA on your iPhone by going to "Settings" and tapping "iCloud."  Afterward, tap your "Apple ID" appearing on the screen, then tap "Password & Security." In the middle of the screen, you will find "Two-Factor Authentication." Turn on 2FA to activate the security feature.

The notification push for 2FA activation has been highly recommended since the aftermath of celebrity iCloud hacking incidents. Hackers have created a solution which could compromise your iCloud password, according to Unlockboot. That is why it is critical to keep up with the hacker's technology by upgrading your protection.

This additional security feature and push notification are available mainly to iPhone users running iOS 9 or later version. Until iOS 10.3 leaves the beta version and a more stable version arrives, notifications will be sent to users encouraging stronger measures against hacking.

Meanwhile, news of a stable 10.3 version is yet to be revealed. Up to now, a beta version is still running, while errors are being checked and recorded for alteration.
