Here is a quote from Pierluigi Paganini in an article published in the Cybernews.com web site:
“Signal: the most secure messaging app?
“The messaging app that is considered most secure by privacy advocates and whistleblowers is, without any doubts, Signal.
“It implements end-to-end encryption and its source code is open source allowing for auditing. The application allows messages to “disappear” after a certain period of time has elapsed and unlike other messaging apps, Signal only stores the metadata it uses to work (i.e. user’s phone number, random keys, and profile information).
“The app also allows its users to set a password to add an additional level of protection and lock it, which means that the messages will still be protected if the phone is inspected by unauthorized people.”
