Signal: WhatsApp is owned by Mark Zuckerberg's Meta, so their encrypted messenger app comes at an ethical cost, when there are perfectly good alternatives. Still in my opinion the original and best, Signal is encrypted, fast, free, open source, and can be used on mobile or desktop, whether you use Windows, Mac, or Linux. In addition, Signal’s video chat option is surprisingly smooth enough to rival Jitsi Meet, and even offers screen-sharing (though not closed captioning). Those wanting something more fun and functional, reminiscent of WhatsApp's look and feel, with less emphasis on open source and encryption, have often opted for Telegram, which sadly became a haven for far-right groups whose members rear their ugly heads in other chatrooms (reflective of the sketchiness of Telegram itself), but we should always stick to the safe spaces, which brings me to the next subject. https://signal.org/en
