How to Install Signal Messaging App on Ubuntu 20.04


Nowadays, Signal is popular among other messaging apps due to its security and end-to-end data encryption. It is an appropriate alternative to Skype, WhatsApp, iMessage, Facebook Messenger, and SMS. It is freely available for all users of iPhone, Android, and iPad. Not only for smartphone users, but Signal also has a Desktop Client for Linux, Mac, and Windows Users. It is a messaging application that has the following features: voice calls, video calls, one-to-one messages, groups, file sharing, photos, stickers, etc. Up to 1000 people can be added to a group chat and more than 8 persons are also allowed in video calling. The other amazing thing is that Signal is funded by donations and is developed by a non-profit foundation. It was thrown in the market for the first time in 2013,  but at the start of 2021, it has been preferred by everyone including Twitter CEO Jack Dorsey, Elon Musk. The reason behind this popularity is that people were more concerned about their privacy and Signal overcame the audience’s fear, as the Signal handles the conversations in an end-to-end encrypted way. This declares the statement that not even the owners of this application can investigate or monitor the conversations. This also caused the Signal application to be at the top of all the store charts of Apple and Google. The signal is a project that is free and fully open-source. Github includes the project’s client application source code and server applications.
