One thing that Telegram now offers to all users is the ability to βdisappearβ messages or set remote deletion deadlines. That enables users to have much more control over how long people can access what youβre sending them. Given that Russian law enforcement officials are reportedly (via Insider) stopping people in the street and demanding to read their text messages, this could be vital to protect individuals from reprisals. Update March 8, 2022: EFF has clarified that Channels and Groups are not fully encrypted, end-to-end, updated our post to link to Telegramβs FAQ for Cloud and Secret chats, updated to clarify that auto-delete is available for group and channel admins, and added some additional links. In a message on his Telegram channel recently recounting the episode, Durov wrote: "I lost my company and my home, but would do it again β without hesitation." The next bit isnβt clear, but Durov reportedly claimed that his resignation, dated March 21st, was an April Foolsβ prank. TechCrunch implies that it was a matter of principle, but itβs hard to be clear on the wheres, whos and whys. Similarly, on April 17th, the Moscow Times quoted Durov as saying that he quit the company after being pressured to reveal account details about Ukrainians protesting the then-president Viktor Yanukovych. Telegram does offer end-to-end encrypted communications through Secret Chats, but this is not the default setting. Standard conversations use the MTProto method, enabling server-client encryption but with them stored on the server for ease-of-access. This makes using Telegram across multiple devices simple, but also means that the regular Telegram chats youβre having with folks are not as secure as you may believe.
