Okta CEO Todd McKinnon believes that the Signal military group chat mishap is a usability issue, not a cybersecurity problem.
McKinnon suggests that Signal could improve its features to prevent accidental contact additions, such as displaying more than just initials as contact icons.
He emphasizes that usability challenges can undermine encrypted messaging platforms and lead to mistakes when sending messages quickly.
McKinnon also highlights the importance of securing the endpoints (devices) on which messaging apps are used, as they contribute to overall security.
