Authentication is the critical process of verifying the truth of an assertion about an entity, most commonly proving a user's identity to a system. Unlike mere identification, which states who someone claims to be, authentication provides concrete proof of that claim. This concept spans diverse fields, from confirming the authenticity of a historical artifact or artwork to securing access to sensitive digital information. In computing, it forms the bedrock of [[cybersecurity|cybersecurity]], preventing unauthorized access to data and systems. The methods employed range from simple [[password|passwords]] and [[biometrics|biometric]] scans to complex [[multi-factor-authentication|multi-factor authentication]] protocols, each aiming to establish a verifiable link between an asserted identity and a real-world entity. Its pervasive application underscores its fundamental role in trust and security across modern society.
