You're not calling your function anywhere so you it wouldn't really work. Also, all GUIs should be called inside the OnGUI function. I modified your code a little. I've tested this one and it works fine with me. Let me know how it will go. xx

 using UnityEngine;
 using System.Collections;
 
 public class Test : MonoBehaviour {
 
     public string levelCode;
     public bool isBlank;
     public bool isWrongKey;
 
     void OnGUI()
     {
 
         levelCode = GUI.TextField(new Rect(100, 100, 250, 30), levelCode);
 
         GUI.Label(new Rect(200, 60, 300, 40), "Enter Level");
 
         if (GUI.Button(new Rect(100,  140, 250, 30), "OK!"))
          {
             GetInput(levelCode);
          }
 
         if(isBlank)
         {
             GUI.Label(new Rect(200, 200, 300, 40), "Invalid Key!");
         }
 
         if(isWrongKey)
         {
             GUI.Label(new Rect(200, 200, 300, 40), "Wrong Key!");
         }
     }
 
     public void GetInput (string guess)
      {
      if ((guess == "pass122") ||(guess == "pass133"))
      {
          Application.LoadLevel("Eat");
           isBlank = false;
          isWrongKey = false;
         //Debug.Log("Load level Eat");
      } 
      else if (guess == "") 
      {
         isBlank = true;
         isWrongKey = false;
         Debug.Log("Invalid Key!");
      } 
      
      else 
      {
         isWrongKey = true;
         isBlank = false;
         Debug.Log("Wrong Key!");
      }
 }
 
 }

Thanks @akisrn. It works fine. But as i mentioned earlier, i want to make the game unlocked using one time password for one device. Similar concept as activation code for an application.

@nurul-shuhadah maybe you can store the password in PlayerPrefs. Something like PlayerPrefs.SetString("myPassword", myPassword); where myPassword is where your password is stored. Then, at the start function, you can use something like if (PlayerPrefs.HasKey("myPassword") { //load level } else { // do what needs to be done if user hasnt saved the password }
