When creating a SecureString variable to store a password, it is important to ensure that the password is not hardcoded directly in the code, as you correctly pointed out. Storing the password directly in the code would defeat the purpose of using a SecureString.
The main advantage of using a SecureString to store a password is to enhance the security and protection of sensitive information, such as passwords, in memory. Unlike a regular string, a SecureString encrypts the characters and stores them in an encrypted format in memory. This helps to prevent the password from being easily accessible or readable by malicious actors who may try to exploit the application.
