Kasutajatuvastus, also known as user authentication, is the process of verifying the identity of a user or system accessing a digital platform or service. It is a critical component of cybersecurity, designed to ensure that only authorized individuals gain access to protected resources. The main goal of kasutajatuvastus is to prevent unauthorized access and maintain the integrity and confidentiality of sensitive information.

There are several common methods of kasutajatuvastus. Password-based authentication requires users to enter a secret password or PIN. This method is widely used due to its simplicity but can be vulnerable to attacks such as guessing, theft, or phishing. To enhance security, multi-factor authentication (MFA) combines two or more verification methods, such as a password, a fingerprint, or a one-time code sent via SMS.

Biometric authentication utilizes unique biological traits, such as fingerprints, facial recognition, or iris scans, to verify identity. This method offers increased security and convenience, as users do not need to remember passwords. Additionally, token-based systems employ physical devices like security tokens or software tokens generating time-sensitive codes.

Kasutajatuvastus is employed across various domains, including online banking, government portals, corporate networks, and mobile applications. The effectiveness of user authentication measures impacts overall cybersecurity posture and user trust. With the growing prevalence of digital services, developing robust and user-friendly kasutajatuvastus systems remains a priority for organizations worldwide.
