CAPTCHAs Have Failed for 20 Years

The article argues that CAPTCHAs have fundamentally failed to achieve their security goals. Despite being in use for two decades, these tests have not stopped automated bots effectively. Instead of improving security, the systems have become increasingly complex and frustrating. Users now face significantly harder challenges that are difficult to distinguish from machine behavior. The blog post explores why these tools are getting harder rather than more effective. It highlights the growing gap between bot capabilities and human tolerance for tedious tasks. The failure of CAPTCHAs suggests a need for alternative methods of verification online. This long-term trend raises questions about the future of web accessibility and security.
