Signal Desktop now includes support for a new “Screen security” setting that is designed to help prevent your own computer from capturing screenshots of your Signal chats on Windows. This setting is automatically enabled by default in Signal Desktop on Windows 11.
If you’re wondering why we’re only implementing this on Windows right now, it’s because the purpose of this setting is to protect your Signal messages from Microsoft Recall.
First announced on May 20, 2024, Microsoft Recall takes screenshots of your apps every few seconds as you use your computer and then stores them in an easily searchable database. In Microsoft’s own words, its goal is to act as a sort of “photographic memory” for everything that you do on your computer. The words that other people chose to describe Recall upon its debut were decidedly less positive. After an intense security backlash and significant public outcry, Microsoft quickly pulled the feature.
