Try

// Correct Credential
string username = "Juan";
string password = "Santos";

//User input username and password
Console.Write("\nUsername: ");
var un = Console.ReadLine();

Console.Write("Password: ");
var pw = Console.ReadLine();


//Condition

if (un == username && pw == password) {
    Console.WriteLine("\nSuccessfully Login.");
} else if (un != username && pw == password) {
    Console.WriteLine("\nYou entered an invalid user name.");
} else if (un == username && pw != password) {
    Console.WriteLine("\nYou entered an invalid password.");
} else if (un != username && pw != password) {
