function GeneratePassword([int] $length = 24) {
  
  # Character sets
  $lowerCase = [char[]]([char]'a'..[char]'z')
  $upperCase = [char[]]([char]'A'..[char]'Z')
  $number = [char[]]([char]'0'..[char]'9')
  $symbol = '_-+#!£$%^&*@,.?~:;'.ToCharArray()
  
  # Initial password
  $pass = ""
  
  # Minimum of one of each type
  $pass += ($lowerCase | Get-Random -Count 1) -join ''
  $pass += ($upperCase | Get-Random -Count 1) -join ''
  $pass += ($number    | Get-Random -Count 1) -join ''
  $pass += ($symbol    | Get-Random -Count 1) -join ''
  
  # Fill in the rest of the character selection
  $pass += ($($lowerCase;$upperCase;$number;$symbol) | Get-Random -Count ($length - $pass.Length)) -join ''
  
  # Randomly shuffle the selected characters
  $pass = ($pass -split '' | Sort-Object {Get-Random}) -join ''
  
  # Print it out
  Write-Host $pass
