Signal vs Telegram: which is more private in 2026?

Published 31 August 2026. Written by the Nyra team.

For privacy, Signal wins. It is end-to-end encrypted by default, and Telegram's regular and group chats are not. Telegram wins on reach, with big groups, channels, and bots. Both require a phone number. Choose Signal for private conversations, Telegram as a broadcast platform, just not a private one.

Signal and Telegram get mentioned in the same breath so often that many people assume they are two versions of the same thing: private chat apps. They are not. One is built first for privacy, the other first for reach, and that single difference decides almost everything else. This page compares them fairly. A note on where we stand: Nyra is our app. It is in development, not launched, and not yet independently audited, so treat its column as the app we are building rather than software you can install today. We included it because it sits in a specific gap that neither Signal nor Telegram fills.

The short version

Signal: built for privacy first

Signal is, plainly, the more private of the two, and for private conversations it is the better choice. Every chat is end-to-end encrypted by default, which means the content is readable only on the devices of the people talking, never by Signal itself. It uses the Signal Protocol, the most scrutinized messaging cryptography in existence, formally analyzed and independently audited many times over. Forward secrecy is built in through the Double Ratchet, so even if one of your keys leaks later, previously recorded messages stay unreadable. Group chats are end-to-end encrypted too. Clients and server are open source, and the whole thing is run by a nonprofit, the Signal Foundation, whose responses to subpoenas have shown it holds almost nothing about its users.

Signal has one requirement that matters here: you must register with a phone number. Since 2024, usernames can hide that number from the people you talk to, which helps, but the number still sits on your account, tied to your identity through your carrier. For most people that is a fair trade for spam resistance and easy contact discovery. For a journalist's source, an activist, or anyone who does not want a real-world identity attached to their conversations, that single field is the whole problem. That is exactly the gap Nyra is being built to fill.

Telegram: built for reach first

Telegram is excellent at what it is designed for, and it is worth being clear-eyed about that. Huge groups, public channels, bots, fast multi-device sync, a slick interface: as a social and broadcast platform it is one of the best, and one of the most-used apps in the world. If your goal is to reach a large audience or run a community, Telegram is genuinely hard to beat.

But the widespread belief that Telegram is a private messenger in the same sense as Signal is simply wrong. Regular Telegram chats are not end-to-end encrypted. They are encrypted only between your device and Telegram's servers, where they are stored and are technically readable by the service. Only secret chats are end-to-end encrypted, and those must be started manually, work one-to-one only, and do not sync across your devices. Group chats and channels are never end-to-end encrypted. On top of that, Telegram's homegrown MTProto protocol has had academic analysis but nothing like the audit depth of the Signal Protocol, and while the client apps are open source, the server is closed. We go deeper on this in our look at whether Telegram is safe.

The verdict

For privacy, Signal wins, and it is not close. It encrypts everything by default, keeps forward secrecy, opens its code, and answers to a nonprofit rather than to advertisers. If your question is which app keeps your conversations unreadable to everyone except the person you are talking to, the answer is Signal.

For reach, Telegram wins. Massive groups, public channels, and a polished social layer are things Signal never set out to do. The mistake is treating Telegram's reach as if it came with Signal's privacy. It does not. Use Telegram as the public square it is, and use something end-to-end encrypted for the conversations you actually want kept private.

Where Nyra fits

There is one group neither app serves well: people who want Signal-grade privacy but cannot, or will not, hand over a phone number. Signal requires one. Telegram requires one and does not encrypt by default anyway. Nyra is our attempt at that missing option. Your identity is a username plus keys derived from a recovery phrase, with no phone number and no email, ever. Messages use X3DH and the Double Ratchet, the same construction Signal pioneered, built on independently audited cryptographic primitives, with forward secrecy intact. Rather than promising zero metadata, which no relay server can honestly promise, we publish exactly what our server can and cannot see, and our security page explains the cryptography in full.

The honest caveats, stated plainly: Nyra is in development, so you cannot install it yet, the code is not yet public, and the independent audit is planned but has not happened. If none of that is a dealbreaker and the phone-number requirement is what pushed you here, Nyra is worth watching. For the wider field, our full messenger comparison lines up Signal, Telegram, Session, SimpleX, and Nyra side by side.
