As the adage goes, there's no such thing as perfect security. And feeling invincible could get you in trouble. End-to-end encryption transforms messages into unintelligible chunks of data as soon as a user presses send. From there, the message isn't reconstituted into something understandable until it reaches the receiver's device. Along the way, the message is unreadable, protected from prying eyes. It essentially amounts to a bodyguard who picks you up at your house, rides around with you in your car, and walks you to the door of wherever you're going. You're safe during the transport, but your vigilance shouldn't end there. [...] It's easy to forget in practice that people you message with could show the chat to someone else, take screenshots, or retain the conversation on their device indefinitely. You also need to keep track of how many devices you've stored your encrypted messages on. If you sync chats between, say, your smartphone and your laptop, or back them up in the cloud, there are potentially more opportunities for the data to be exposed. Your chats may be encrypted, but your backups may not. Text:
