Authentication is the process of verifying the identity of a user or entity, while authorization is the process of granting or denying access to specific resources based on a user's verified identity. Authentication methods include username and password, and biometric authentication. Authorization is managed through policies, such as Role Based Access Control and Attribute Based Access Control.
