bool confirmed = false;
string Key;
do {
Console.Write("Please enter a login key: ");
Key = Console.ReadLine();
Console.WriteLine("You entered, " + Key + " as your login key!");
ConsoleKey response;
do
{
Console.Write("Are you sure you want to choose this as your login key? [y/n] ");
response = Console.ReadKey(false).Key; // true is intercept key (dont show), false is show
if (response != ConsoleKey.Enter)
Console.WriteLine();
} while (response != ConsoleKey.Y && response != ConsoleKey.N);
confirmed = response == ConsoleKey.Y;
} while (!confirmed);
Console.WriteLine("You chose {0}!", Key);
Console.ReadLine();
