Login limit attempts in C#

hop of those help? Since you start with attempt = 1 and you increase it on each try, you only really get two tries:
after the first try, attempt will be 2, which is less than 3, so your second try checks again, but sets attempt to 3 your third try now is no longer < 3, so you get the message that the limit's been reached

            _failedAttempts++;
            //lblError.Text = ("Fail. " + (3 - _failedAttempts));

            if (_failedAttempts == 3)
            {
                SqlConnection con1 = new SqlConnection(connstring);
                SqlCommand mycomm1 = new SqlCommand("SP_IsBlocked", con1);
                mycomm1.CommandType = CommandType.StoredProcedure;
                con1.Open();
                mycomm1.Parameters.Add("@IsBlocked", SqlDbType.VarChar).Value = "Yes";
                mycomm1.ExecuteNonQuery();
                con1.Close();
                lblError.Text = "You are Temporarily Blocked for Exceeding Max Number of Login Attempts";
            }


        } 
        else
        {
            object FailedLoginCounter = this.Page.Cache["UserKey_" + this.txtPwd.Text];
            if (FailedLoginCounter == null)
            {
                FailedLoginCounter = 0;
            }
            this.Page.Cache["UserKey_" + this.txtPwd.Text] = (int)FailedLoginCounter + 1;
            if (((int)this.Page.Cache["UserKey_" + this.txtPwd.Text]) == 3)
            {
                SqlConnection con1 = new SqlConnection(connstring);
                SqlCommand mycomm1 = new SqlCommand("SP_IsBlocked", con1);
                mycomm1.CommandType = CommandType.StoredProcedure;
                con1.Open();
                mycomm1.Parameters.Add("@IsBlocked", SqlDbType.VarChar).Value = "Yes";
                mycomm1.ExecuteNonQuery();
                con1.Close();
                lblError.Text = "You are Temporarily Blocked for Exceeding Max Number of Login Attempts";
            }
        }

Hope that helps The while ( 1 ) { } construct repeats whatever is inside the {} to infinity, unless you explicitly break from the loop. That's a loop, btw.
How could you break from it after a number of attempts? You could have a counter that gets incremented with every attempt and break from the loop at the limit:
code :
if ( ++counter >= limit )
    break;
while ( ++counter < limit )

it fixes the issue Assuming you have implemented the make:auth artisan command of laravel. Inside of the loginController, change the properties:
protected $maxLoginAttempts=5; to protected $maxAttempts = 5;

around this issue Cookies are not a reliable method.
I can create a script that sends whatever cookies I want in the request.
code :
$ip = $_SERVER["REMOTE_ADDR"];
mysqli_query($connection, "INSERT INTO `ip` (`address` ,`timestamp`)VALUES ('$ip',CURRENT_TIMESTAMP)");
$result = mysqli_query($connection, "SELECT COUNT(*) FROM `ip` WHERE `address` LIKE '$ip' AND `timestamp` > (now() - interval 10 minute)");
$count = mysqli_fetch_array($result, MYSQLI_NUM);

if($count[0] > 3){
  echo "Your are allowed 3 attempts in 10 minutes";
}
CREATE TABLE IF NOT EXISTS `ip` (
  `address` char(16) COLLATE utf8_bin NOT NULL,
  `timestamp` timestamp NOT NULL DEFAULT CURRENT_TIMESTAMP
) ENGINE=MyISAM DEFAULT CHARSET=utf8 COLLATE=utf8_bin;
mysqli_set_charset($connection, "utf8")
header("Location: ../login.php");
include("../login.php");
header("Location: http://example.com/login.php");
SELECT `user_id`,`username`,`user_password`,`user_firstname`,`user_lastname`,`user_role` FROM users WHERE ...


while (list($db_user_id,$db_username,$db_user_password,$db_user_firstname,$db_user_lastname,$db_user_role ) = mysqli_fetch_array($select_user_query, MYSQLI_NUM)) {

seems to work fine You can exit from the while loop by placing a break; statement.
In your program change the following
code :
  if(input.equals(password)) 
      System.out.println("Congratulations");
  if(input.equals(password)) 
  {
      System.out.println("Congratulations");
      break;
  }
