What is the difference between authentication and authorization?

They take a look but unfortunately you do not have the VIP role, and therefore are not authorized to access.Put as simply as possible, authentication verifies the identity of a user or service allowing access, whereas authorization determines what they can do once they're in. Why Should You Implement Both Authentication and Authorization?

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.
