User Identification
User identification is the process of uniquely recognizing and distinguishing individual users within a system, application, or service. It involves collecting and verifying user credentials, such as usernames, email addresses, or biometric data, to establish a user's identity. This foundational concept enables personalized experiences, access control, and security measures in digital environments.
Developers should learn user identification to implement secure authentication systems, manage user sessions, and comply with privacy regulations like GDPR or CCPA. It is essential for building applications that require user accounts, such as e-commerce sites, social media platforms, or enterprise software, to ensure data protection and prevent unauthorized access.
