You will be tasked with validating the password protection system for an application. The primary goal is to ensure that the password protection system is robust and secure$,$ preventing unauthorized access and potential threats.

Python Coding Requirement: Develop Python scripts to automate the testing of the password protection system.

Task $1$: Identify Possible Threats to the Password Protection System. List and explain the principal threats to the password protection system.

Task $2$: Develop Tests for Each Threat. For each identified threat, develop specific test cases to assess the effectiveness of the password protection system in mitigating the threat. Implement these test cases using Python scripts.

Task $3$: Validation Approach and Tools. Describe your approach to validate the password protection system, detailing the testing methodologies and techniques you plan to employ. Include Python libraries and tools you will use for testing.

Task $4$: Report and Recommendations. Present your findings from the validation process, including test results and insights gained. Include any Python code used for testing in an appendix to your report.
