What is the difference between authentication and authorization?

It is vital to note the difference here between authentication and authorization. Authentication verifies the user (Lucia) before allowing them access, and authorization determines what they can do once the system has granted them access (view sales information). Authorization systems exist in many forms in a typical technology environment.

What is authentication & why is it important?

Authentication is the process of verifying user identity before giving them permission to access a system, account, or file. Its main purpose is to verify (“authenticate”) a user’s identity. It also keeps out suspicious or malicious users since their identities will not be verifiable.

How does credential based authentication work?

Credential-based authentication works by comparing user-provided credentials to a database record. When there is a perfect match between the two, users can access the account. Authorization is the process of verifying a user’s access level to a system, account, or file.

What is the difference between authentication and access control?

Access control enforces these policies. If we compare authentication and access control, the comparison between authentication and authorization still applies. Authentication verifies the user's identity, and access control uses this identity to grant or deny access.
