authentication
Authentication is the process of verifying that someone is who they claim to be. In everyday life, this can be seen when you present an ID to enter a building or access your bank account. In the digital world, authentication often involves passwords, security questions, or biometric data like fingerprints or facial recognition. The goal is to protect sensitive information and ensure that only authorized individuals can access certain systems or services. Proper authentication helps to prevent fraud and identity theft, keeping personal and organizational data secure.

Authentication is the process of verifying the identity of a person or system. It ensures that someone is who they claim to be before granting access to information or services. For example, when you log into your email, you provide a username and a password; if they match what the system has on file, you're authenticated and allowed to access your inbox. Authentication can also involve additional methods, like biometric scans (fingerprints or facial recognition) or security questions, to enhance security and prevent unauthorized access.
