Signal for Mac users should disable notifications to keep their messages secure

If you’re using Signal for secure messaging, here’s something to be aware of. The app is one of the best-regarded encrypted messaging tools out there, but Mac owners who use Signal might inadvertently be putting their privacy at risk.

As Motherboard reports, security researcher Alec Muffett discovered that Signal messages sent to a Mac can persist in the notifications center, even if you have the app’s settings tuned to delete them.

That fact suggests that otherwise private messages live on in the operating system, which is something other researchers are looking into at the moment.

It’s a serious concern for anyone who relies on the Signal Mac app, but remember: to take advantage of this flaw, a hacker would need to compromise or obtain your Mac, and by then it’s probably game over.

To turn off the setting — and we recommend that you do — go to the Settings menu within the Signal for Mac app and select either “Neither name nor message” or “Disable notifications” to make sure that your private messages don’t stray beyond Signal.
