Reads a line of input from the console. The Read-Host cmdlet reads a line of input from the console (stdin). You can use it to prompt a user for input. Because you can save the input as a secure string, you can use this cmdlet to prompt users for secure data, such as passwords. NOTE: Read-Host has a limit of 8190 characters it can accept as input from a user.

-AsSecureStringIndicates that the cmdlet displays asterisks (*) in place of the characters that the user types as input. When you use this parameter, the output of the Read-Host cmdlet is a SecureString object (System.Security.SecureString).

-PromptSpecifies the text of the prompt. Type a string. If the string includes spaces, enclose it in quotation marks. PowerShell appends a colon (:) to the text that you enter.
