Signal Responds to Windows 11’s Controversial Recall Feature
Signal has taken a firm stance against the Recall feature integrated into Windows 11, actively implementing safeguards to prevent the AI tool from capturing screenshots of conversations within its desktop application. In response, Signal has introduced a new “Screen Security”setting for Windows 11 users, which is enabled by default to protect user communications from potential breaches associated with Recall’s monitoring capabilities.
The Controversy Surrounding Windows Recall
Initially revealed in May 2024, Windows Recall ignited significant controversy among cybersecurity experts and the public due to its implications for user privacy. The negative feedback prompted Microsoft to postpone the feature’s initial June 2024 launch, opting for a revamp that included making it an opt-in feature and requiring Windows Hello for access. By November 2024, Recall began its testing phase with Windows Insiders and gradually rolled out to Copilot+ PCs starting in April 2025.
Signal’s Ongoing Concerns
Despite recent modifications to the Recall feature, Signal maintains that it poses a significant risk to user privacy. The organization stated:
Although Microsoft made several adjustments over the past twelve months in response to critical feedback, the revamped version of Recall still places any content that’s displayed within privacy-preserving apps like Signal at risk. As a result, we are enabling an extra layer of protection by default on Windows 11 in order to help maintain the security of Signal Desktop on that platform even though it introduces some usability trade-offs. Microsoft has simply given us no other option.
Implementation of Enhanced Protection
Signal Desktop now employs a Digital Rights Management (DRM) flag on its application window to bolster privacy. According to Signal, this technical maneuver aligns with Microsoft’s own guidelines:
According to Microsoft’s official developer documentation, setting the correct Digital Rights Management (DRM) flag on the application window will ensure that ‘content won’t show up in Recall or any other screenshot application.’ So that’s exactly what Signal Desktop is now doing on Windows 11 by default.
Visual Impact and Usability Trade-offs
This strategic implementation renders Signal chats invisible to Recall, appearing as a black screen not only to the Recall feature but also to any attempts at manual screenshots. While this may present some usability challenges and affect specific accessibility tools, Signal does offer users the choice to disable “Screen Security, ”albeit with a cautionary warning.
Call for Enhanced Developer Tools
Signal’s team expressed disappointment over Microsoft’s lack of more refined tools for developers, stating, “Microsoft has launched Recall without granular settings for app developers that would enable Signal to easily protect privacy, which is a glaring omission that limits our choices.”They further emphasized that, “Apps like Signal shouldn’t have to implement ‘one weird trick’ in order to maintain the privacy and integrity of their services without proper developer tools.”
In light of these developments, Signal advocates for better privacy practices and tools in the developer community, pushing for greater emphasis on user security in app functionalities.
