The popularity of messaging apps in Android smartphones has been increasing since their release. However, with time, there has been growing concern over these apps’ security and privacy features. As a result, new encrypted messaging apps are becoming popular.
The encrypted instant messaging apps promise to protect users’ privacy as they do not track or read users’ messages.
Secure messaging apps tend to keep users’ privacy intact with a feature called end-to-end encryption (E2E).
A message is called end-to-end encrypted if any third party, including the service provider, cannot access the messages from the servers.
In simple terms, only the people communicating with each other can read the messages. No one from outside, neither the government nor the developers, can access it.
