Rebecca does not like her school friends to read her text messages. She does not give them her mobile phone but you know how kids are! So, Rebecca wonders if there is a way to put a password on her text message inbox.

Text messages (SMS) have become an integral part of modern day communication for all sort of purposes. So, it is needless to say that people have begun to feel the need to secure their text message inbox. Text messages are private in nature but mobile phone may not always be in your hand. Visiting friends, relatives  and their kids often ask you to unlock your phone so that they can see its features. At this time your SMS inbox becomes all open to the person holding your phone. There could be hundreds of similar situations wherein you would pray that the person does not open text messages.

Gone are the days of old mobile phones where securing messages was a problem. Now, with smartphones, it is pretty easy to put a password not only on your SMS inbox but also on any application (app) in your mobile phone. This password would be separate from your mobile phone password which is used to lock/unlock the device itself. So, this provides extra security.

For this purpose, you can use Privacy Master  — Free App Lock Android app. As the name suggests this app is available free of cost and could be downloaded from Google Play store on your mobile phone. Once installed, this app allows you to put a password on any app including text messages.
