Signal is where I keep up with my security research friends and family!

Everytime I talk to someone on here they try and extort me …. It’s disgusting
This app has, by far, surpassed any other discreet/secure messaging (for free) that I’ve ever heard of. I’m a huge fan of the Proton group, so I openly recommend it, but first, I always, always insist on Signal. I’ve used it for years, and the only problems I’ve ever had (MAYBE twice) were my own failing to update the app to enable continuity of it being secure. Highly recommend, and already recommend to anyone I actually want to communicate with.
….I have messages that I know my family member has read as it shows in info the time they read it and then i open again and it shows not read but still read in the info. It makes me think that very possibly local law enforcement is using there back door surveillance to be nosy on people’s emails. Nothing to see, nothing to hide yet that is like having one’s diary read. So sad this world we live in. It’s not right! It’s much like Harriet on little house on the prairie listening in on conversations when she was running the connecting of phone calls. Yes, all except for what is typed already I appreciate signal.
Thanks for where you start from me and I do help where you help me till and I can never forget the way you’re treating me may you also get the same I happy for ch age my life
I’ve been using this app for a while now and I would say it’s far better than even WhatsApp, more private and more
Morgan Moyer
I really enjoy using this app, it is so clean and neat! I feel this app is better than WhatsApp
See above, sign in process is too confusing
Perfect for private chat…
Signal is a good app overall, but it’s really buggy sometimes and crashes so I lose my messages.
Very lovely and nice app to use
Smooth as buttered ham! Always secure and safe while fast and easy.
Then bring them to signal. It’s not all what you’d expect. Everyone has someone and if that person is absent then fight to find them.
