Authentication Methods
Authentication methods are techniques and protocols used to verify the identity of users, systems, or entities in computing environments, ensuring that only authorized parties can access resources. They form a critical component of security systems, ranging from simple password-based checks to complex multi-factor and biometric systems. These methods are foundational to implementing secure access control in applications, networks, and services.
Developers should learn authentication methods to build secure applications that protect user data and comply with regulations like GDPR or HIPAA, especially in scenarios involving user logins, API access, or sensitive transactions. Understanding these methods is essential for implementing robust security in web development, mobile apps, and enterprise systems to prevent unauthorized access and data breaches.
