User Authentication

User Authentication is the process of verifying the identity of a user attempting to access a system or application. This verifies that the user is who they claim to be, typically through the use of credentials such as a username and password. User authentication may involve additional methods like multi-factor authentication (MFA), which requires users to provide multiple forms of identification, such as a text message code or biometric data (like a fingerprint).

The core purpose of user authentication is to ensure that unauthorized individuals cannot gain access to sensitive information or functionalities of a system, thus protecting user data and maintaining security and privacy. It is a fundamental aspect of cybersecurity and is implemented in various scenarios, including online banking, social media platforms, and enterprise applications. Different authentication methods may vary in their reliability and usability, leading to ongoing developments in technology aimed at improving user authentication processes.
