Signal is a secure messenger that is widely touted as one of the best options. This Signal review shows you the pros and cons.
"When you use Signal, your data is stored in encrypted form on your devices. The only information that is stored on the Signal servers for each account is the phone number you registered with, the date and time you joined the service, and the date you last logged on."
This isn't an ad, I wasn't paid for this post. Just to clear the air: fuck facebook, fuck elon musk and twitter, fuck anyone who thinks this is a paid advertisement. I wish I was paid for this shit, I just wanted to spread the word. Thank you. 😀 👍
I've been using signal for a few years. I'm now in a situation that I use two different phones but signal only allows you to be connected to a single device, and you only see the messages in your history for the particular device you received it on. You can't migrate messages, the UI is extremely basic and isn't a responsive design so you have no control over window size on larger screens. There's just so many annoying little things about it, but overall it's pretty solid. I'm looking for a better solution now though.
It really needs some more effort put in on UI design, data migration and linked devices. Development is very slow. I hoped it would improve but nothing has changed for years.
