I really like Signal
I'm switching all my texting and messaging to it as much as possible, and this is my urging that you do too. First and foremost, due to security, of course, but…
The user interface is slick and beautiful and just sooooo responsive.
There's a destop app that integrates seemlessly and stays synced to your phone(s) and other computers, so you can type on a keyboard when near one, instead of tapping on a screen! Yet is still fully mobile when you aren't near a legit computer.
My biggest fear was that setup would be a pain, with all sorts of tech knowledge needed, and passwords, and private keys, etc. No. Nothing like that. Just install the app and you're good to go. It syncs your contact list from your phone and auto-fills it with anyone else who has Signal.
And, of course, the security. Fully encrypted end-to-end, so no one else can read your messages. Not the NSA, not Facebook, not Google, not the phone company, or any service provider. Your conversations actually remain your own. And it's free!
Very importantly, this is good to use AT ALL TIMES. If people only use Signal for illicit talk, that means it's obvious that anyone using Signal is doing something shady. Once you use it for everything, all the time, out of a matter of principle because it ain't nobody else's business what the hell you're saying to your mom or your bae or your boss, there is a normalization of using encryption all the time. Which is as it should be.
I know this sounds like an ad or some shit, but I'm just really excited and happy about this. 4 out of 5, would encrypt again! https://signal.org/
