Web authentication is the process of verifying a user's identity before granting access to web based resources. This typically involves a user providing credentials, such as a username and password, which are then checked against a stored record. Web authentication is crucial for protecting sensitive data and ensuring that only authorized individuals can access specific applications or information. For instance, logging into your online banking portal uses web authentication to secure your financial accounts. It differs from session management, which tracks a user's activity after they have been authenticated. You will encounter web authentication concepts in cybersecurity certifications like CompTIA Security+ and CySA+.
