WhatsApp and Signal are two of the most widely used instant messengers with end-to-end encryption support. Both of them have got pretty similar features. Both instant messengers have one thing in common and that is Brian Acton who was the co-founder of WhatsApp and now he has been appointed interim CEO of Signal.

The creator of Signal app Moxie Marlinspike announced that he is resigning from the post of CEO at Signal Messenger LLC. He has now appointed Brian Acton as an interim CEO while he will focus on looking for the new candidates. Acton who was the co-founder of WhatsApp with Jan Koum in 2009 and also co-founded as well as funded the Signal Foundation with Marlinspike in 2017 is currently at the post of executive chairman of Signal. Marlinspike will remain on board and his involvement in Signal app will remain the same as he is just leaving the CEO position.
