Prompt for password if the -p flag is not supplied

Recently, I ran this tool for the first time without specifying the -p flag. Instead of prompting for a password, the tool attempted a blank password, resulting in a quick account lockout, where I couldn't kill the scan before it was too late. Adding a feature that prompts for a password when not specified with the -p flag would be beneficial to prevent future lockouts. Thank you!

Start by locating the command-line handling for the -p flag and the code that initiates the scan. Confirm the behavior when the flag is omitted, then implement an interactive password prompt that avoids attempting a blank password and verify the scan uses the entered value.
