Signal, it’s all about security. Signal is used by notorious figures in cybersecurity and data privacy, such as Edward Snowden and Bruce Schneier! That’s because in Signal all communication is encrypted end-to-end by default (and it’s one of the few encrypted messaging apps which employ this default system). Recently, the app received a $50 million investment from the WhatsApp co-founder Brian Acton which is supporting the non-profit Signal Foundation’s mission of “making private communication accessible and ubiquitous”. Signal is also WIRED’s secure messaging recommendation to use it because “it’s free, it works on every mobile platform, and the developers are committed to keeping it simple and fast by not mucking up the experience with ads, web-tracking, stickers, or animated poop emoji.”
