Setting a lock code on your smartphone is highly recommended to protect your personal information, but sometimes a lock code can be a bit inconvenient.
What if you could do away with the device lock code, instead locking only the apps you want to keep private? An Android app named App Lock let's you do just that. That's not to say you can't use App Lock in addition to the lock code on your device, adding an extra level of security to your information.
App Lock, free in the Android Market, allows you to set a lock code or pattern on an app-by-app basis, preventing unwanted access to any app you deem private.
Setting up and using App Lock is a breeze.
- After installing and opening the app for the first time, you'll be asked to set a lock code. After setting a lock code, you will have to set a security question.
- After setting up a required security clearance, you can set up the apps that will require a lock code. Toggling the switch next to the respective app will enable the code requirement for that app.
- Before exiting the app, there is one important option you will want to turn on. Tap on the System Lock tab and toggle the Install/Uninstall switch to "on." Doing so will require a passcode in order for App Lock to be uninstalled. With this option turned off, if someone were able to get his hands on your device, he could uninstall App Lock and access your information.
- Going forward you will have to enter your PIN (or pattern) to access any of the apps you have enabled App Lock for.
