Authentication is the process of verifying the identity of a user, ensuring that they are who they claim to be. Authorization, on the other hand, is the process of determining what actions a user is allowed to perform within a system or application, based on their authenticated identity. In simpler terms, authentication confirms your identity, while authorization determines what you are allowed to do once your identity is confirmed. **

This process helps to prevent unauthorized individuals from receiving the package and adds an extra layer of security to the delivery process. **

The security risk with 2-factor authentication lies in the potential vulnerabilities of the second factor. For example, if the second factor is a text message or phone call, it could be intercepted by a hacker. Additionally, if the second factor is a physical token or device, it could be lost or stolen. Furthermore, if the second factor is a biometric such as a fingerprint or facial recognition, it could be spoofed. These vulnerabilities could potentially compromise the security of the 2-factor authentication process. **
