New Free Ebook Guide Aims to Demystify Signal for Privacy-Conscious Users

Exclusive: Free Signal Guide Released

A comprehensive new ebook titled Everybody Has Something to Hide: Why and How to Use Signal to Preserve Your Privacy, Security, and Well-Being is now available for free download in both English and Spanish. The guide, authored by tech evangelist and EFF donor Guy Kawasaki, provides step-by-step instructions and context for using the encrypted messaging app Signal.

The ebook is published in EPUB format and can be accessed directly through the Electronic Frontier Foundation's website. It covers everything from basic setup to advanced privacy features, aiming to make secure communication accessible to all users.

“In an era of mass surveillance, Signal offers a rare combination of strong encryption and ease of use,” said Guy Kawasaki. “This guide removes the fear factor and shows that protecting your privacy is not only necessary but straightforward.”

The release comes amid growing concerns over data breaches, government surveillance, and corporate data mining. Signal, which uses end-to-end encryption by default, has seen a surge in adoption among journalists, activists, and ordinary users seeking to safeguard their conversations.

Background

Signal is widely regarded as one of the most secure messaging platforms available, with its encryption protocol adopted by other major apps like WhatsApp. However, its advanced features—such as disappearing messages, screen security, and link previews—can be intimidating for new users. The EFF has long championed digital privacy and previously released two short guides on Signal: an introductory How to Use Signal guide, and a detailed Managing Signal Groups guide.

Kawasaki’s ebook builds on these resources by offering a narrative-driven approach that contextualizes privacy within everyday digital life. He draws on personal anecdotes and real-world scenarios to explain why “everybody has something to hide”—even seemingly ordinary people.

“Privacy isn't about hiding illegal activity; it's about maintaining autonomy and dignity,” said an EFF spokesperson. “Guy’s guide makes that case convincingly while providing practical tools.”

Signal’s rising popularity has also attracted scrutiny. Some governments have attempted to ban or weaken encryption, arguing it hinders law enforcement. The ebook addresses these debates head-on, presenting counterarguments grounded in human rights and security research.

What This Means

The availability of a free, authoritative guide lowers the barrier to adopting strong encryption for millions of users. By demystifying Signal’s settings and encouraging best practices, the ebook could help shift the default behavior of casual messaging users toward more secure habits.

Security experts note that widespread encryption adoption reduces the attack surface for mass surveillance and data theft. As more people use Signal, the network effect strengthens the platform’s utility and resilience.

• Increased privacy literacy: The guide explains concepts like metadata exposure, contact discovery, and verification of safety numbers in plain language.
• Cross-platform reach: Available in English and Spanish, with potential translations to follow, the ebook targets a global audience.
• Community trust: Kawasaki’s long association with EFF lends credibility; the organization has been a leading voice for digital rights since 1990.

For those already using Signal, the guide offers advanced tips—such as how to manage groups effectively and how to avoid common privacy pitfalls. The EFF recommends pairing the ebook with their existing guides for a comprehensive learning path.

“We encourage everyone to download this guide and share it with friends and family,” the EFF spokesperson added. “Secure communication is a team sport, and every new Signal user makes the ecosystem stronger.”
