Why the EFF Recommends Signal

If you care about privacy and secure communications, you’ve probably heard the Electronic Frontier Foundation (EFF) recommend Signal. But what exactly makes Signal stand out in the crowded messaging app landscape? In this article, we’ll dive into why the EFF endorses Signal, what features make it a top choice for privacy-conscious users, and how you can get started with it today.

What Is the EFF and Why Does Their Recommendation Matter?

The Electronic Frontier Foundation (EFF) is a leading nonprofit organization focused on defending civil liberties in the digital world. They advocate for user privacy, free expression, and transparency. When the EFF recommends a tool like Signal, it’s based on rigorous evaluations of security, privacy, and ease of use.

Signal regularly appears on the EFF’s Secure Messaging Scorecard as a top performer, receiving high marks for encryption, open-source code, and minimal data retention.

Why Does the EFF Recommend Signal Specifically?

Here are the key reasons that make Signal stand out in the EFF’s eyes:

End-to-End Encryption: Signal uses the Signal Protocol, a state-of-the-art encryption method that ensures only you and your recipient can read your messages. Even Signal’s servers can’t decrypt your communication.
Open Source and Auditable: Signal’s code is publicly available on GitHub, allowing security experts worldwide to inspect, audit, and improve it. This transparency builds trust and accountability.
Minimal Metadata Collection: Unlike many messaging apps, Signal collects very little user data. It doesn’t store message contents or contact lists on its servers, minimizing risks if the servers are compromised.
Forward Secrecy: Signal regularly generates new encryption keys to protect your past communications even if a current key is compromised.
Strong Privacy Features: Signal offers disappearing messages, screen security to block screenshots, and encrypted voice and video calls, all designed to maximize privacy.
No Ads or Trackers: Signal is a nonprofit supported by donations, so it doesn’t monetize your data or display ads.

How to Get Started Using Signal: A Step-by-Step Guide

If you want to follow the EFF’s advice and switch to Signal, here’s how to do it easily:

Download Signal: Go to signal.org and download the app for your device—iOS, Android, or desktop.
Register Your Number: Open the app, enter your phone number, and verify it with the SMS or call code.
Set Up Your Profile: Choose a display name and optionally add a profile picture. This info is stored locally and encrypted.
Import Contacts: Signal can scan your contacts to show who else is using Signal. You decide whether to grant access to your contacts.
Start Messaging Securely: Begin chatting by selecting a contact or entering a phone number. All messages and calls are end-to-end encrypted automatically.
Enable Privacy Features: Explore settings like disappearing messages, screen security, and registration lock PIN to enhance your protection.

Additional Tips to Maximize Your Signal Privacy

Using Signal effectively means taking advantage of its privacy-centric features. Here are a few practical tips:

Activate Disappearing Messages: In any chat, tap the contact’s name at the top, then choose “Disappearing Messages.” Set a timer from 5 seconds to 1 week to automatically delete messages after viewing.
Use Registration Lock: Go to Settings > Privacy > Registration Lock and enable this PIN feature. It prevents someone else from registering your phone number on Signal without your PIN.
Block Unknown Senders: Enable this feature to avoid spam or unwanted messages from people not in your contacts. Find it under Settings > Privacy > Blocked Contacts.
Verify Safety Numbers: For extra security, verify the safety numbers with your contacts. This ensures your encryption keys haven’t been tampered with. Tap the contact’s name > tap “View Safety Number” & compare via a secure channel.

Why You Should Trust Signal and the EFF

In an era where data breaches, government surveillance, and corporate tracking are common, having a secure communication tool is essential. The EFF’s recommendation of Signal is based on its robust security model, transparency, and commitment to user privacy without compromising usability.

By choosing Signal, you’re using a tool designed not just to protect your messages, but to empower you with control over your digital communications. For more information on Signal’s security and the EFF’s evaluations, visit
