It is a known fact that apps rule the smartphones. Infact if the apps weren’t brought into the smartphone then there wouldn’t be much use of the smartphone anyways. But with many apps comes the need to protect your apps from folks other than you accessing these apps. Realistically speaking, there are chances that a colleague at work may be fascinated by your smartphone and my want to try some apps, or your kid at home may want to play games on your phone and may want to access few apps. These are situations that you cannot forecast or prevent. However, if you have an Android phone what you can do is to set lock codes on individual apps. So almost all smartphones now allow you to set lock codes for the main phone access, but none of the phones actually provide application level access codes.
Very interestingly this app level access security is provided by another app, called App Lock. This is a free app on the Android marketplace and basically it lets you set a lock code or pattern on an app-by-app basis. Once you have installed the app when you open the App Lock 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 in case you forget the access information for App Lock. This is a one-time configuration that App Lock requires of you. Once this is done you can select the apps for which you want to set up the lock code. All the apps will appear in a list and then all you have to do is toggle the switch next to the respective app to enable the code.
This basically adds another layer of security to your phone and it may be extremely essential if you are using apps that contain confidential personal or professional information.
