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.

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

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.
