It really depends on who your friend is, and who they are trying to defenf against.

If the US ( or Russian / Chinese) government really wants to access an internet-connected device, they can do it; what app you are using doesn't even matter. For example, most people use the default Google keyboard, which could be compromised.

If the concern is about local goons / employers / coworkers, then both Telegram and Signal are more than enough to stop them prying.

As for whether to use Signal or Telegram, Signal has end to end encryption enabled by default, while in Telegram you have to switch it on for each chat. On the other hand, Telegram has the best UI among messaging apps hands down.

Telegram is not end to end encrypted. Repeating it's not. Only private mode or something like that is.

Telegram for random public chatter/file storage(with password lock), talking to strangers without giving them your number. Signal for personal/private conversations.

Spread your data (encrypted or not) around, so a single entity doesn't own your digital life. Your device can handle 2 apps and don't give them permissions willy nilly. Geez, every one of these posts just wants to start a flame war.

In my view, by far the biggest reason to switch is that Telegram doesn't end-to-end encrypt chats by default.

Yes you can start encrypted chats specifically, but i'll bet 99% of chats on telegram aren't encrypted - meaning whoever has access to the telegram servers can read all the messages.

Signal claims to end-to-end encrypt all chats by default, and if you want to be 100% sure you can in theory read the source code and compile the app yourself. this means signal cannot read any of your messages, even if police asks them to or servers get seized. That's a massive advantage in privacy.

Telegram rolls their own crypto. That should be the biggest red flag by far. I say this as a telegram user

While there may be better options out there, from a purely security standpoint.

The real world, with non-tech people needs solutions that are easy, fast and as close to foolproof as possible.

I choose Signal, because my mum, my sisters and brothers (none of which are tech people) can all go to their app stores and install Signal, it works and it is easy. Signal is private BY DEFAULT, I don't have to remind them to turn on security for each chat, there is voice and video chat for individuals and groups, I can use it to send files. It is really good. Secure communication is their primary goal.

I have been using Signal since it was called TextSecure and I only had one contact using it.

Yes it sucked when they dropped SMS support; but these days about 98% of my messaging goes through Signal. Any SMS is usually from my doctor/dentist/bank.

I never really trusted Telegram, too many compromises. Secure communication is not their primary goal.

Telegrsm is not secure anymore. USA have all the keys of the encriptions of telegrsm.

Telegram doesn't even encrypt group chats. And it doesn't encrypt private convos by default.

I can't speak about telegram, but signal is absolutely not secure to use. Its a US-based service (that must adhere to NSLs), and requires phone numbers (meaning your real identity in the US).

Matrix, XMPP, or SimpleX are all decentralized, and don't require US hosting.

There’s a lot of answers itt but heres a simpler one:

If you want to prevent people in power from having access to communications there are two methods employed, broadly speaking:

The first is to make a very secure, zero knowledge, zero trust, zero log system so that when the authorities come calling you can show them your empty hands and smirk.

Signal doesn’t actually do this, but they’re closer to this model than the second one I’m about to describe. Bear in mind they’re a us company so when the us authorities come to their door or authorities from some nation the us has a treaty with come to their door signal is legally required to comply and provide all the information they have.

The second is to simply not talk to the authorities. Telegram was closer to this model than signal, using a bunch of different servers in nations with wildly different extradition and information sharing mechanisms in order to make forcing them to comply with some order Byzantine to the point of not being worth it.

Eventually the powers that be got their shit together and put hands on telegrams owner so now they’re complying with all lawful orders and a comparison of the tech is how you’d pick one.

The technology behind the two doesn’t matter really but default telegram is less “secure” than default imessage (I was talking with someone about it so it’s on the old noggin’).
