If you have no idea what the Signal app is used for and whether it is safe, this guide provides the answers you seek.

Signal is a messaging app known for its focus on privacy and security. The app experienced a significant surge in popularity after Elon Musk's tweet encouraging users to 'use Signal' in response to the controversial privacy policy changes introduced by WhatsApp.

In this guide, we will provide you with insights into the uses of Signal and address the question of whether this messaging app is a safe choice for your communication needs.

What is the Signal app used for?

Signal is a messaging app that is used for sending text messages, making voice and video calls, and sending multimedia messages such as images and videos. It offers a wide range of communication features while prioritizing privacy and security.

People who value strong privacy and security in their messaging app and want to ensure their conversations remain confidential typically use Signal. It's favoured by activists, journalists, privacy advocates, and anyone who seeks a secure communication platform.

Signal uses a cryptographic protocol known as the Signal Protocol (formerly known as the TextSecure Protocol) developed by Open Whisper Systems, which is the same organization that created the Signal app.

It is worth mentioning that other popular messaging apps such as WhatsApp and Facebook Messenger use the Signal Protocol for the end-to-end encryption of their messages, ensuring a high level of security and privacy for their users' communications.

Is the Signal app really safe?

The Signal app is really safe due to its robust end-to-end Encryption, open-source code, and minimal data collection practices. In fact, it is the most secure messaging app in 2023.

Signal employs strong end-to-end encryption, ensuring that only the sender and recipient of a message or call can access its content. This means that even Signal itself cannot read your messages or listen to your calls.

Moreover, Signal's open-source code allows for transparency and scrutiny by the security community, enhancing trust in its privacy and security measures. It also enables independent audits and contributions to continually improve the app's security.

Furthermore, Signal's commitment to minimal data collection means that it gathers only essential user information. The app collects only your phone number as part of its user registration, and this data is kept separate and not associated with your identity.

And that covers everything about the Signal app. While you are here, make sure you check out whether WhatsApp is safe and Snapchat is encrypted. Also, look at how private and secure is Discord.
