I don&#x27;t understand why people on HN are still recommending Telegram. It&#x27;s not open, the crypto is highly questionable, and messages are not encrypted end-to-end by default (and not at all in groups). Use one of the apps that gets a full score in the EFF&#x27;s Secure Messaging Scorecard [1], like Signal.<p>[1] <a href="https:&#x2F;&#x2F;www.eff.org&#x2F;secure-messaging-scorecard" rel="nofollow">https:&#x2F;&#x2F;www.eff.org&#x2F;secure-messaging-scorecard</a>
