Authentisatie

Authentisatie, also known as authentication, is the process of verifying the identity of a user or device attempting to access a system or resource. It ensures that the entity presenting itself is indeed who or what it claims to be. This is a fundamental security measure in computing and information systems.

There are several common methods used for authentication. One is something the user knows, such as a password or a PIN. Another is something the user has, like a security token, a smart card, or a mobile device receiving a one-time code. The third category is something the user is, which involves biometric data such as fingerprints, facial recognition, or iris scans.

Multi-factor authentication (MFA) combines two or more of these independent categories to provide a more robust security layer. For instance, entering a password and then confirming a code sent to a phone is an example of MFA.

The goal of authentication is to prevent unauthorized access and protect sensitive data from being compromised. It is a critical component in secure online transactions, access to confidential information, and the overall integrity of digital systems. The strength of an authentication method often dictates the level of security provided.
