What is the difference between authentication and authorization?

What's the difference between authentication and authorization? Authentication confirms that users are who they say they are. Authorization gives those users permission to access a resource. While authentication and authorization might sound similar, they are distinct security processes in the world of identity and access management (IAM).

What is user authorization?

Authorization is the process of verifying a user’s access level to a system, account, or file. User authorization ensures that only authorized users can access the assets they need and only to the extent allowed by the system. Computer systems can leverage many types of authorization strategies, such as Role-Based Access Control (RBAC).

Can a user change the authentication credentials?

2FA/MFA (Two-Factor Authentication / Multi-Factor Authentication) The authentication credentials can be changed in part as and when required by the user. The authorization permissions cannot be changed by user as these are granted by the owner of the system and only he/she has the access to change it. The user authentication is visible at user end.

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.
