Security locks in Smartphones

If you leave your Smartphone unattended for a while or in the worst case it was stolen by someone, the best way to protect your personal information on the phone is by setting up a security lock. Setting up a security lock means PIN or Password is required to access your phone after an inactive period.

Best App Lockers For Android

Android is undoubtedly one of the most popular and widely used smartphone operating system. Android phones are equipped with a lot of security lock options. Few of the important once are listed below.

Smart Phones – Types Of Locks

  • WiFi/Location

How secure is your smartphone’s lock screen?

The fact that the FBI managed to hack the iPhone of the San Bernardino shooter without Apple’s help raises questions about whether PIN codes and swipe patterns are as secure as we think. In fact, they’re probably not as secure as we’d hope. No device as complex as a smartphone or tablet is ever completely secure, but device manufactures and developers are still doing their best to keep your data safe.

9 best ways to secure your smartphone

    1. Bluetooth

      I can use Trusted Bluetooth to keep my phone unlocked and ready to act on voice commands at all times. Once I connect to a ‘trusted device’, I unlock the phone once and it’ll stay unlocked until I disconnect or decide to lock the phone using the button in the notification panel. And if I walk out of range of my device, it locks. So if my device walks off, or I do, my data is safe. Easy, but still secure.

    2. Knock Code

      LG’s addition to the device security party was Knock Code, which was then brought to many other current LG phones. It’s simple, it’s not as finicky about where on the screen you tap as PIN or password locks, and it’s almost fun, as far as methods of unlocking your phone go.

    3. WiFi/Location

      As mentioned, Pebble Locker will also allow you to lock your device based on WiFi networks. SkipLock is yet another option for this. While WiFi-based unlocking takes a bit more setup sometimes, it’s also very handy to those who use it, and even without Pebble Locker or SkipLock, I know many a Tasker user who uses WiFi or a geo-fenced location to remove their lock screen and use their phone freely in their home.

    4. Fingerprints


      I’m personally not really the biggest fan of replacing my fingerprint with the same fingerprint we leave smudged all over the device and the same fingerprint we give to the government. That said, hacking fingerprints still requires effort and intent, and most people quite simply don’t have that. And fingerprints are perfect for the crowd that otherwise wouldn’t lock their phone. Just remember not to fall asleep or pass out drunk around anyone who would want into your phone.

    5. NFC Unlock


      Another feature from the Moto X that will hopefully come to more phones in the future: NFC unlocking. You have NFC tags, which can come in a plethora of sizes/shapes/colors/forms, even tattoos, which once they’re written and recognized by your device will unlock your phone when you tap them. The great news is that they’re easy and NFC tags are quite cheap and easy to accommodate to your life and habits. The bad news is that NFC tags are not something you can turn off or lock.

    1. Password


      Password, a real QWERTY password, is the original way to lock and secure a computer, and is still available to users who want a more robust lock method. And if you encrypt your phone, you are required to use either a password or a PIN, so passwords are still used by a good many users on their phones. Passwords are harder to crack, but they’re also harder to put in one-handed. And while Trusted Bluetooth, NFC, and other sensor- based unlock methods can help our phones stay unlocked longer, you will still end up using your traditional lock screen method at least four to five times a day.

    1. PIN


      In terms of lock methods, PIN is second only to pattern in popularity. They’re slightly harder to be guessed out by swipes, they can vary in length, and they’re easy to copy down in a discreet place if you’re the forgetful type. PINs are also a little harder to suss out from the smudges on the screen since they’re not connected like a pattern.

    2. Pattern

      The most popular lock method in that poll from the beginning of the month is the pattern lock. It’s simple, yet if you use all the dots – or if you can make an even bigger grid for the pattern to be woven through – pattern locks can be pretty secure. Patterns are also easy to remember through a variety of methods: you can equate each of the nine dots with the number that would sit there on a number-pad, or you can tie it into the wallpaper that sits behind it.

  1. A word about Face Unlock

    Face Unlock has been loitering in Android for a few years now, and it’s not very popular, and there’s a few reasons for it. First, even a three year old can can hack it with Mommy or Daddy’s photo, so in a selfie-crazy society letting your mug unlock your phone may not be the best thing in the world.
