Your Signal PIN is the code used to support features such as identifiers that are not associated with a phone number. This means your PIN can restore your profile, settings, contacts, and list of people you’ve blocked if you ever lose or change your device. Also, the PIN code can serve as an additional registration block that prevents someone else from registering your number on your behalf. To make this possible, Signal has developed Secure Value Recovery technology (https://signal.org/blog/secure-value-recovery/ ), which keeps your social graph inaccessible to Signal’s servers. This differs from other programs and platforms that store such data on their servers in the form of plain text. This means that no one but the participants of the conversation has access to the information. Even developers can’t read correspondence. Messenger does not collect user data.
Signal is a classic messenger. The program allows you to write messages, create single and group chats (up to 1000 participants maximum), make voice or video calls (up to 8 users at the same time), exchange photos, emojis and videos, share location and contacts. The program can be used instead of standard SMS. A feature of the messenger is encrypted device-to-device (E2EE) messages.
