Whatsapp vs Telegram vs Signal - which is secure and private?

Описание: In this video, we break down the real differences in security and privacy between WhatsApp, Telegram, and Signal—three of the most widely used messaging apps in the world. While all of them market themselves as “secure,” the reality is far more nuanced, especially once you look beyond basic encryption claims.

We’ll compare how each platform handles end-to-end encryption, metadata collection, cloud backups, and default security settings, and why those details matter more than most users realize. Signal is often considered the gold standard for privacy, WhatsApp balances strong encryption with heavy metadata collection under Meta, and Telegram offers flexibility—but with important trade-offs that many users misunderstand.

Crucially, this video also explains a major risk that affects all three platforms: SIM swap attacks. Because WhatsApp, Telegram, and Signal all rely on phone numbers for account registration and recovery, an attacker who hijacks your mobile number can potentially take over your messaging account. We’ll explain how SIM swaps work, why they bypass even strong encryption, and what happens when an attacker re-registers your number on a new device.
