Authentication

The process of verifying a user's identity before granting access to systems.

A core layer of cybersecurity that prevents unauthorised access.

‍

Ensures only authorised users access sensitive systems. For instance, a manager logging into payroll may need both a password and a fingerprint, reducing the risk of stolen credentials being used fraudulently.

Multi-factor authentication is common; but you should also consider more advanced authentication strategies such as adaptive authentication policy, which dynamically adjust contextual factors like location and device in real time.
