Apple has just made two big security-related changes to the iOS 9 — and chances are, you may not have even heard about them.

Apple is now pushing users to put in a six-digit passcode instead of the usual four-digit one, and two-factor authentication will now become a built-in part of the iOS, as well as the OS X, according to a MacWorld report.

The first changes makes it 100 times harder to crack the passcode compared to a four-digit code, Brute-forcing 10,000 codes into an iOS may not seem very likely, but researchers have found a way to do it — a process that can take anywhere from a few seconds to 17 hours, but nevertheless in all cases is possible.

Adding two digits to push it to six characters makes it a lot harder to crack a truly random passcode. Now, it may take a cracking routine up to seven months to break the code.

Apple is also introducing two-step verification, which it initially added in March 2013. Currently, Apple relies on notifications and the Find My iPhone conduit in order to give a four-digit token to users to prove that they are the legitimate owner — something that isn’t even necessarily required if you have an Apple ID.

However, Apple is now integrating two-step verification into iOS 9 and OS X 10.11, although the full details aren’t yet available.

Still, two-step systems won’t be a perfect system to prevent a security breach. But it will help deter phishing, when someone is fooled into giving their password. In order for that password to be useful, someone will have to have access to the second factor that gains entry. This will also be beneficial when passwords are stolen from other sites.
