When enabled, display screen safety will set a Digital Rights Administration (DRM) flag on Sign’s app home windows, blocking their content material from being captured by Recall or different Home windows apps and options.
Microsoft launched Recall in Might 2024 when safety specialists described it as a privateness nightmare and a major safety threat as a result of attackers might simply weaponize it to steal consumer knowledge.
To handle these issues, Microsoft made Recall a detachable opt-in characteristic that requires customers to sign up utilizing Home windows Hey and upgraded it to filter out delicate info (like credentials and bank card numbers) and to exclude some apps, web sites, or non-public shopping periods from being captured.

“Because of this, we’re enabling an additional layer of safety by default on Home windows 11 as a way to assist keep the safety of Sign Desktop on that platform regardless that it introduces some usability trade-offs. Microsoft has merely given us no different possibility.”
Sign’s display screen safety may trigger points with display screen readers, so those that need to flip it off can achieve this from Sign Settings > Privateness > Display safety.
Sign will even present an alert earlier than turning off display screen safety, warning that Home windows can take screenshots of their Sign chats as soon as the characteristic is disabled.
“Apps like Sign have basically no management over what content material Recall is ready to seize, and implementing ‘DRM’ that works for you (not in opposition to you) is the only option that we had,” Lund added.
”We hope that the AI groups constructing techniques like Recall will suppose via these implications extra rigorously sooner or later. Apps like Sign should not should implement ‘one bizarre trick’ as a way to keep the privateness and integrity of their providers with out correct developer instruments. Individuals who care about privateness should not be compelled to sacrifice accessibility upon the altar of AI aspirations both.”
Nevertheless, as Lund added, enabling Sign’s display screen safety in your gadget is not going to defend in opposition to screenshots or recordings by others utilizing display screen readers on macOS or Linux gadgets.
In April, nearly one 12 months after its introduction, Microsoft began rolling out Home windows Recall to all prospects who put in the Home windows 11 KB5055627 replace on Copilot+ PCs.
