Two questions.
My family insist on using Whatsapp for the family chats. I have to keep a copy on a device just so I can communicate with them. I do so under protest, as I was always told it isn't secure. My brother has just said
"oh Whatsapp is encrypted, it's perfectly secure".
First, is it actually as encrypted and safe as my brother claims? That would solve everything.
Second, if it isn't, where can I get some proof that we should switch to Telegram or whatever? Proof which doesn't make me look like a raving loony?
No Telegram lol. Thats way worse. Whatsapp sais they are E2EE but its all "trust me bro" because you cannot look at the code.
With Telegram its a little pain to open encrypted chats and groups are always unencrypted. So its useless.
Let them try Signal, its nearly identical but you can trust it.
Iunno if I would say that Signal can be trusted considering their ties to the US State Dept
The beauty of using Signal with an open-source Signal client is that you don't need to trust them, which is kind of the point.
