This example generates 7000 passwords with default length (15 characters) and default structure(25% UpperCase letters, 25% LowerCase letters, 30% numbers and 20% special characters. PS> Get-RandomPassword -NoOfPasswords 7000 -OpenInTextFile It will also create and open a temporary text file with the passwords.
