Artem Kliuchnikov and his family fled Ukraine just days before the Russian invasion. I want a secure messaging app, should I use Telegram? Such instructions could actually endanger people — citizens receive air strike warnings via smartphone alerts. Telegram was founded in 2013 by two Russian brothers, Nikolai and Pavel Durov. Telegram does offer end-to-end encrypted communications through Secret Chats, but this is not the default setting.

This makes using Telegram across multiple devices simple, but also means that the regular Telegram chats you’re having with folks are not as secure as you may believe.
