What is the difference between authorization and authentication?

Authentication is the process of verifying a user's identity, that is, confirming that the user really is who they claim to be. This usually involves entering a login and password, biometric data, or one-time codes.

Authorization is the process of determining the user's rights and access to resources after successful authentication. For example, after logging in, it is determined which pages or functions are accessible to the specific user.

Example: you enter your login and password (authentication), the system checks them, and if everything is correct, it allows you to view certain data or perform actions (authorization).
