Have object always lookAt camera

Question

I'm a total newbie with C# and I'm trying to modify this script so that instead of having to manually assign a target to the script in the editor, it would just assign the main camera to be the object to look at. I have tagged my camera with the MainCamera tag in case it helps. Here is the code that I'm using:

 using System.Collections;
 using System.Collections.Generic;
 using UnityEngine;
 
 public class alwaysFaceCamera : MonoBehaviour {
 
 
     public Transform target;
 
 
     // Use this for initialization
     void Start () {
 
     }
 
     // Update is called once per frame
     void Update()
     {
         // Rotate the camera every frame so it keeps looking at the target
         transform.LookAt(target);
     }
 
 }

Here's what seems to work:

 using System.Collections;
 using System.Collections.Generic;
 using UnityEngine;
 
 public class alwaysFaceCamera : MonoBehaviour {
 
 
     private Transform camera;
 
 
     // Use this for initialization
     void Start () {
 
         camera = Camera.main.transform;
 
     }
 
     // Update is called once per frame
     void Update()
     {
         // Rotate the camera every frame so it keeps looking at the target
         transform.LookAt(camera);
     }
 
 }

What if the main camera is always changing, is there any better solution instead of calling Camera.main in Update()?
