To fix this issue, the password should be generated using a cryptographically secure random number generator instead of the insecure System.Random. In C#, the recommended approach is to use System.Security.Cryptography.RNGCryptoServiceProvider (or RandomNumberGenerator since .NET Core). The GeneratePassword function should be updated so that instead of Random.Next(), it uses cryptographically random bytes (via RNGCryptoServiceProvider.GetBytes or RandomNumberGenerator.GetBytes). The password string can then append a securely-generated random integer, by converting securely generated random bytes to an integer. Make sure to add the appropriate using directive (using System.Security.Cryptography;) to the top of the file if not already present.
You only need to modify the GeneratePassword function accordingly, within MyProj/Program.cs.

Pull Request Overview
This PR adds a password generation function to the program. The change introduces a new GeneratePassword() method that creates passwords using a random number appended to a base string, and calls this function to output a generated password.

Using System.Random for password generation is cryptographically insecure. Replace with System.Security.Cryptography.RandomNumberGenerator to generate cryptographically secure random values for passwords.

The password uses a fixed predictable prefix 'mypassword', making it easily guessable. Use a completely random or hash-based approach instead of appending random numbers to a static string.
