Signal encrypts messages and calls end-to-end by default and publishes open-source clients. Telegram’s default cloud chats are encrypted between the client and Telegram’s servers and stored in the cloud; only Secret Chats are end-to-end encrypted (Telegram FAQ). If you never enable Secret Chats, Signal’s default is the stronger privacy posture."},{"question":"Does Telegram use end-to-end encryption by default?","answer":"No. Telegram’s FAQ states that Secret Chats are end-to-end encrypted and that ordinary cloud chats are stored on Telegram’s servers so they can sync across devices. Signal’s default 1:1 and group chats are end-to-end encrypted. Do not treat “Telegram is encrypted” as the same claim as “Telegram is end-to-end encrypted by default.”"},{"question":"Which is better for large groups and channels?","answer":"Telegram. Official docs describe groups with a very large member cap and Channels for one-to-many broadcasts, plus a public bot API. Signal supports encrypted groups sized for private circles, not public broadcast communities. Use Telegram for public or very large communities; use Signal for private groups."},{"question":"Can I use Signal or Telegram without a phone number?","answer":"Signal still registers with a phone number and offers optional usernames so contacts need not see that number (Signal Support). Telegram also uses a phone number to create an account and can show a username in public contexts (Telegram FAQ). Neither is a pure email-only messenger."},{"question":"Which is better for everyday family chat?","answer":"It depends who is already installed. If the goal is private family chat with default end-to-end encryption, Signal matches that job. If the family already lives in Telegram groups or Channels, Telegram is easier — but default cloud chats are not end-to-end encrypted. There is no MAU ranking."},{"question":"Signal vs Telegram for business — which should teams use?","answer":"Neither is a full WhatsApp Business replacement. Telegram documents bots, Channels, and large groups that creators and communities use. Signal has no official business API. For customer messaging with a verified business profile, see WhatsApp Business instead. For private staff chat, prefer Signal if everyone can install it."},{"question":"Are Signal and Telegram both open source?","answer":"Signal publishes its clients and the Signal Protocol. Telegram publishes clients and documents its APIs, but default cloud-chat encryption is not the same as Signal’s default end-to-end model. Open source does not by itself make Telegram’s default chats end-to-end encrypted."}],"relatedComparisons":[{"slug":"signal-vs-whatsapp","title":"Signal vs WhatsApp","category":"technology"},{"slug":"whatsapp-vs-telegram","title":"WhatsApp vs Telegram","category":"technology"}],"relatedBlogPosts":[],"expertAnalysis":"Signal or Telegram depends on default privacy versus large-community features. No user counts are added.\n\nPrivacy and encryption\n\nSignal encrypts chats and calls by default and publishes protocol and client source. Telegram’s FAQ distinguishes Secret Chats (end-to-end encrypted, device-to-device) from cloud chats (stored on Telegram servers so they sync). Treat that distinction as load-bearing: a Telegram group or Channel is not a Secret Chat.\n\nFeatures and communities\n\nTelegram documents large groups, unlimited-audience Channels, bots, and large file transfers. Those are the reasons people pick Telegram for public communities. Signal’s feature set is narrower and privacy-oriented (disappearing messages, sealed sender, usernames).\n\nChoose Signal if every participant can install it and you want default end-to-end encryption. Choose Telegram if you need Channels, bots, or very large groups and accept that default cloud chats are not end-to-end encrypted.
