Whatsapp is a powerful communication application with over a billion users across more than 180 countries worldwide.
Whatsapp messenger enables people to keep in touch with friends and families.
It allows people to chat and make video/internet calls across networks.
One other very powerful feature that makes Whatsapp a unique communication application is the fact that when you use a particular phone number to set up the application on your phone initially, you can insert another SIM card with a different number to continue using the application in case you do not have immediate access to the original number used.

5 Easy Steps to Create Whatsapp Group
Typically, no one should have the ability to add someone to a chat group outside the admin who created the group.
By right, end-to-end encryption is to be implemented to ensure nobody is able to have access to the chat messages between the group members.
Not even at the server end should anyone be able to read or view such messages in plaintext.
This is to ensure that information is kept within the limit of the group members alone.
But researchers from the German-based Ruhr-Universität Bochum (RUB) indicates anyone who controls Whatsapp/Signal servers is capable of adding new members to any private group keeping them there to spy up the group’s conversation without authorization of the administrator.
Besides, the administrator will not even be aware of this that his/her group’s privacy has been compromised.
Although, Whatsapp came out to deny the Whatsapp flaw claim saying communications on the network are well secure and that the messages are encrypted end to end especially on communication between user to user.
The truth remains that no matter the mechanism in place, system end-to-end encryption is paramount so there will be guaranteed protection of privacy as people use the chat service to communicate.
Of course, communication technology will continue to grow especially in this year 2018, stakeholders in the industry must note that while they strive to grow the solutions and investments, the privacy and safety of users is absolutely key.
And users, on the other hand, must also research about any system they engage with for their own safety and privacy.
