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 on...
I think signal should also warn a user if their communicating partner has disabled this feature. A user is in control of their own screen security, but if the other side still “recalls” their messages, it’s pointless.
