I love Signal because of the automatic end-to-end encryption. Even though Whatsapp now has that, too, I still prefer Signal because it's more transparent about key handling. I would love them to add an opportunity to use it without a phone number. This is the only thing I don't like because you can't stay anonymous when using Signal.

This app got a 100% rating on the EFF's Secure Messaging Scorecard.

WhatsApp and Telegram are not completely open and are not as secure as Signal!

Regardless of who endorses him, Moxie is hostile to anyone that threatens his control over the project. He also has a very high opinion of the Google Play store despite that coming with Google's ToS and Google Play Services. He does everything he can to shutdown alternative modes of distribution. I would read this before installing and contributing to Signal's userbase, especially if open source and/or F-Droid are things you care about.

I am not an expert but i appreciate the thought that you put into your criticism. Most importantly i appreciate the alternatives that you listed. I'm checking into Tox right now.

It is the best, no doubt about that. But be aware, if you need to reset your smartphone you will loss all your old chats. Be aware! In order to preserve your chats install Signal in your desktop, laptop, tablet and backup. Remember Signal is not able to read the user messages, so not even ask.

I was satisfied with it, but now that they will be removing SMS functionality there is a good chance I will be looking for something else.

One thing for sure is that I will stop recommending Signal to friends and family. SMS integration was very useful to most of them also. They are not going to be happy that I once recommended Signal to them.

    No phone number. You can choose a good server, but communicate with all. You can run it over Tor. The app is easy to use but full of features, that Signal still dreams of. There are Apps for every platform, in every Form.
