According to Engadget, Google Chrome will begin defaulting to secure HTTPS connections starting in April 2024 for users with Enhanced Safe Browsing enabled, with a full rollout to all users scheduled for October 2026 with Chrome 154. The transition follows years of gradual implementation, with Chrome first alerting users to insecure HTTP websites in 2018 and beginning to default to HTTPS in April 2021. Currently, 95 to 99 percent of Chrome navigations already use HTTPS, but Google notes the transition has plateaued, leaving users vulnerable to attacks that can hijack single insecure navigations. When the “Always Use Secure Connections” setting is enabled, Chrome will request permission before first accessing any public website that doesn’t use HTTPS, though private sites like local IP addresses and company intranets will continue to use HTTP due to certificate complexities. This represents Google’s latest effort to close remaining security gaps in web browsing.

The Technical Evolution Behind the Change
The shift from HTTP to HTTPS represents one of the most significant security transformations in internet history. While many users simply notice the padlock icon in their browser, the underlying communication protocol changes are profound. HTTPS encrypts the entire communication between browser and server, preventing eavesdropping, tampering, and message forgery. What makes Google’s latest move particularly significant is that it addresses the “last mile” problem – those remaining HTTP connections that users might accidentally trigger through mistyped URLs or outdated bookmarks. The technical implementation requires sophisticated fallback mechanisms since Chrome must handle cases where HTTPS simply isn’t available without breaking the user experience entirely.
Beyond the Obvious Security Benefits
While the primary benefit is clearly protection against man-in-the-middle attacks, the implications run deeper. Many modern web features, including geolocation APIs, service workers, and progressive web app capabilities, require HTTPS connections. By making HTTPS the default, Google Chrome is essentially future-proofing the web platform and enabling richer, more capable web applications. This also has significant privacy implications – even when the content itself isn’t sensitive, HTTPS prevents internet service providers and network administrators from seeing exactly which pages within a site users are visiting, since the specific URLs and parameters remain encrypted.
The Practical Challenges Ahead
The phased rollout strategy reveals several practical challenges Google must navigate. The two-and-a-half year timeline between initial and full deployment suggests significant testing is required to ensure compatibility with legacy systems and internal networks. Many organizations still operate internal web applications that rely on HTTP, and sudden changes could disrupt business operations. The permission-based approach for first-time HTTP access represents a compromise between security and usability, but it creates a potential user experience friction that Google will need to monitor carefully. Additionally, the distinction between public and private sites creates a gray area that sophisticated attackers might exploit, particularly in corporate environments where the line between internal and external resources can blur.
Broader Industry Implications
Google’s decision will likely create a domino effect across the browser industry. Other major browsers, including Safari, Firefox, and Edge, will face pressure to implement similar defaults, potentially accelerating the complete phase-out of unencrypted web traffic. For web developers and hosting providers, this represents the final push to ensure all resources – including images, scripts, and external dependencies – are served over HTTPS. The remaining HTTP holdouts, often legacy systems or poorly maintained websites, will face increasing pressure to upgrade or risk losing traffic entirely. This move also strengthens the position of certificate authorities and SSL/TLS providers, who have seen certificate costs decrease dramatically with the advent of free options like Let’s Encrypt.
The End of Plain Text Web
Looking beyond 2026, we’re likely approaching the point where HTTP becomes the exception rather than the rule. The remaining use cases for unencrypted connections – primarily local network devices and development environments – may eventually be addressed through alternative security mechanisms. The success of this transition will be measured not just in the percentage of HTTPS traffic, but in the reduction of successful attacks that exploit unencrypted connections. As web security continues to evolve, this milestone represents a crucial foundation for more advanced security features and privacy protections that will define the next generation of web browsing.
