Public Wi-Fi is generally safe for users. Modern system and network security mechanisms, most notably the widespread deployment of TLS, provide adequate protection against nearly all common network-level attacks. Despite this, public Wi-Fi is frequently characterized as inherently insecure by security agencies, experts, and commercial vendors. In some cases, these claims rely on outdated assumptions and contribute to fear, uncertainty, and doubt (FUD), particularly when commercial incentives are present. In this work, we argue that the blanket characterization of public Wi-Fi as insecure constitutes a security myth that should be reconsidered. We review the current state of wireless local area network security and outline directions for empirical work, including user studies and a systematic analysis of security advice, to strengthen the evidence base against this security myth.
