User Authentication
User authentication is a security process that verifies the identity of a user attempting to access a system, application, or resource, typically by validating credentials such as usernames and passwords. It ensures that only authorized individuals can gain entry, protecting sensitive data and functionality from unauthorized access. This concept is fundamental to cybersecurity and is implemented across various technologies and platforms.
Developers should learn user authentication to build secure applications that protect user data and comply with privacy regulations, such as GDPR or HIPAA. It is essential for any system requiring user accounts, including e-commerce sites, banking apps, and social media platforms, to prevent breaches and maintain trust. Understanding authentication helps in implementing features like login, session management, and access control effectively.
