Explore a comprehensive talk from EuroPython 2017 that delves into replacing traditional password-based authentication with more secure multi-factor methods. Learn about the vulnerabilities of password systems and discover alternative authentication factors such as email-based authentication, one-time passwords (OTP), and hardware keys. Gain insights into implementing these advanced security measures in Python-based web applications, with a focus on Django projects. Understand the pros and cons of each method, including the security benefits of U2F hardware keys and the potential issues with biometric authentication. Walk away with practical knowledge on how to enhance the security of your applications and protect user data from increasingly sophisticated cyber attacks.
