How Secure Is Your Android Smartphone Passcode?
We have heard a multitude of scary stories with the words “privacy” and “smartphone”. We try to avoid storing personal photos on the cloud, set complicated passwords for our email accounts and protect our smartphones with passcodes and security locks. However, danger seems to be approaching from a place we may not have expected.
According to the Norwegian University of Science and Technology, our phone lock patterns are very predictable. That means, that people who somehow get their hands on your phone without your permission, may be able to unlock it and get access to loads of your personal data in an instant.
Having analyzed over 4,000 patterns for her thesis, Marte Loge, a graduate of the Norwegian University of Science and Technology, found that 77% of passcodes started in one of the four corners, and 44% started specifically in the top left one.
Among other findings were the facts that most users used only 4 numerals for their passcodes, as opposed to 8, and a large number of users made their passcodes in the form of letters: C, M or N.
There are a few things you can do to get more protection. One of the simplest things you can do is actually just wipe your screen for finger smudges – so that others can not trace the passcode by following those. Among other precautions, use as many symbols as possible, don’t start in the corner and try to alternate numbers.
With newer OS versions and certain smartphone models, you will also be able to benefit from more advanced security options, like Fingerprint Lock or Face Recognition.
Android 5.0, in particular, comes with a nice set of security features, known as the Smart Lock feature. There, you will have more options to protect your device, and do that without too much extra effort. Read more in How To Use Smart Lock In Android 5.0.
