Signal Desktop on Windows 11 now includes a 'Screen security' setting that prevents screenshots of Signal chats, in response to Microsoft's Recall feature, which captures screenshots of apps every few seconds. This setting is enabled by default to protect user privacy. Recall was initially met with backlash and was pulled, but has since been revamped and reintroduced. The Recall feature still poses a risk to privacy-preserving apps like Signal, prompting the implementation of this new setting.
