If you don’t want your text messages read by prying eyes, you should consider locking your phone with a passcode or facial recognition. But that wouldn’t stop wireless companies, law enforcement, or hackers from reading your most mundane SMS missives—even without physical access to your phone.Although that sounds scary, there’s some good news: Your text messages may already be secure if you use an app that offers a form of security called end-to-end encryption, or E2EE, and you can take a few extra steps to make it much harder for snoops to see your texts.
