Security signal vs telegram11/13/2023 This means that someone who has access to Telegram's servers can listen in.ĭisappearing messages: Signal messages in any individual or group chat can be set to disappear within anywhere from five seconds to one week. Telegram has end-to-end encrypted, one-on-one video calling as well as a voice-chat feature that allows large groups to hold conversations in which members can come and go. Telegram's group voice chats are encrypted from the client device (i.e., a phone or desktop) to the server, but not from one end to the other. Signal's encrypted calls can be made individually or contain up to 40 users in a group. Voice and video calls: Both platforms have voice and video calling. (There's no Secret Chat equivalent for groups.) Signal groups can include up to 1,000 users while Telegram allows up to 200,000 group members. Again, Signal's is end-to-end encrypted, while Telegram's is not. Group chats: Both platforms offer a group messaging option. If you want to protect your communications in Telegram from the company itself, you'll have to start a Secret Chat. Individual messages: Signal's individual messages are encrypted end-to-end by default, while Telegram's basic one-on-one chats are not. Telegram: Featuresīoth apps are similar when it comes to chat options. (But you'll want to keep your Telegram password a very close secret.) Signal vs. Changing phones isn't a problem at all, as multiple devices can be logged into a single Telegram account as long as they use the same phone number. (You can also move your account to a new phone that uses the same number as the old one, as long as you're not switching from Android to iOS or vice versa.)Ĭhanging phone numbers in Telegram is a lot easier and can be done right within the app. It now permits you to port your account to a new number provided you're still using the same phone. Until earlier this year, Signal required you to create a new account if you changed your phone number. Telegram provides a similar QR code, but you can also use your phone number and an SMS verification code. Signal has an in-app QR code for linking other devices. This step is optional, but recommended, with Telegram and can be found under Settings > Privacy & Security > Passcode Lock.īefore you can enable a desktop version of either Signal or Telegram, you must set up your account via the mobile app. Signal then requires you to create a PIN. You'll be asked whether you want to enable app permissions, such as access to your contacts. You can use an alias or, with Signal, an emoji. (In some cases, Telegram will call you with the code instead.)īoth platforms require a first name to finalize your profile, but neither require that name to be your real name. The installation process for both apps is relatively simple: Download the software for your preferred platform, register using your phone number, and enter the verification code received via SMS. Linux ( Debian-based distros for Signal, 32-bit and 64-bit versions for Telegram) Signal vs. Both Signal and Telegram are available on the following platforms: Telegram has a slight edge in this category, with a Chrome browser extension and a fully web-based option. The brothers no longer live in Russia and even though their company is based in London, many of its central operations are in Dubai. While Signal is owned by a non-profit foundation, Telegram was founded by the Russian billionaires Pavel and Nikolai Durov who also created the country’s largest social network, VK. For those who are concerned about tech companies snooping on their private conversations, Signal once again proves to be the better choice. That matters when the authorities show up at Telegram’s facilities with a search warrant.Īlthough you can start Signal chats by typing in another person’s phone number, Telegram requires access to your contacts before you can message anyone. ![]() In contrast, Telegram’s metadata may include your IP address (which can give away your location) as well as who you are talking to and when. Signal generally only stores the date on which you created your account as well as the last time you connected. Signal also collects far less data on users than Telegram does. ![]() Still, the paper added that “further investigation” is needed “in order to deem this protocol suite definitely secure”. ![]() ![]() However, the consensus seems to be that the latest version is more secure than MTProto 1.0 (PDF).Īccording to an academic research paper published in 2020, Telegram’s MTProto 2.0 protocol is fundamentally sound. Many security experts have stated that Telegram’s " homegrown encryption technology" has a limited track record compared to Signal's. For its encrypted Secret Chats, Telegram uses its own MTProto 2.0 protocol which is open source on the client side.
