You can download the Signal app from the Android and iOS stores like any other app.

Since you need to install Signal on your phone before you can use it on the desktop, we'll talk about the mobile version first.

To test everything out for this Signal review, I installed Signal on an Android smartphone and also a Windows 10 desktop.
It would be great to see more transparency reports, on a regular schedule, like we see with other services. Signal published their first and only transparency report in 2016. For a current list of such audits check out this page in the Signal Community Wiki. Beyond this original audit, there have been several other formal and informal audits of aspects of the product. This analysis has been updated several times since, with the same conclusion. Conducted by researchers from Germany, Switzerland, the United States, and Canada, the audit showed that the protocol was cryptographically sound. The first formal security analysis of the Signal protocol was conducted in 2016. To do this, you'll want to read this article on backup and restore options. However, because your data is all encrypted and stored on your device, you will need to configure Signal to back it up if you want the ability to restore your data. This is also different from apps like Wire messenger that encrypt your data but store some of it on their servers. This is different from apps like WhatsApp, which actually collects your metadata for their own use (and passes it along to Facebook too). 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. When you use Signal, your data is stored encrypted on your devices. Signal encrypts your metadata, and stores it on your device. While all secure messenger services apply encryption to your messages, most don't do the same for your message metadata.
It uses Curve25519, AES-256, and HMAC-SHA256 for its encryption algorithms. If you want the technical side of things, the protocol is built on the Double Ratchet algorithm, triple Elliptic-curve Diffie–Hellman (3-DH) handshake, and prekeys. This open source code has been heavily audited and is so good that it is used for E2E encrypted messages by WhatsApp, Skype, and Facebook Messenger. Many in the security community consider Signal to be the most secure end-to-end (E2E) encryption system available for voice, video, and instant messaging conversations.

The LLC is funded by the Signal Technology Foundation (aka Signal Foundation), a 501(c)(3) non-profit organization that publishes all its products as free and open-source software (FOSS). This company now has responsibility for developing the Signal app and the Signal Protocol that provides its security. Marlinspike and Brian Acton founded Signal Messenger, LLC in 2018. In 2013, Matthew Rosenfeld (commonly known as Moxie Marlinspike) founded Open Whisper Systems to develop the Signal app and protocol. Signal is a product of Signal Messenger, LLC. Signal Messenger is available for the iOS, Android, Mac, Windows, and Linux operating systems. If you are looking for a secure messaging app with things like the leading secure messaging protocol (the Signal protocol), client-side end-to-end (E2E) encryption, data synced across multiple devices, and a very low price (free), then you should keep reading and learn more about Signal. However, there are other options for these types of users, as we noted in our Wickr Review. There are no special business or educational versions so if you need corporate features like centralized user control, Signal isn't for you.

Signal offers a full range of features for personal secure messaging. If you want some additional proof that Signal is worth your attention, consider this: during the great 2021 exodus of users from WhatsApp, Telegram and Signal were the two apps that people were most likely to switch to. By the time we're done, I think you will agree with me that this app should be on your secure messaging app short list.
In this Signal review, we will examine the security and features of Signal. It relies on the internet for all its encrypted communication and is regarded as the best when it comes to privacy and security. A free and open source application ( FOSS), Signal uses end-to-end encryption to securely communicate with other Signal users. Signal Messenger is perhaps the most secure messaging app available.
