The counting and count-checking needs to be done inside the loop, plus you need to break the loop when the limit is exceeded and then check the count before printing the welcome:

var ingresar_clave = prompt('Ingrese su contraseña');
var password = 'cometa';
var contador = 0;
while (ingresar_clave !== password) {
  contador += 1;
  if (contador >= 3) {
    alert("Ha sobrepasado el limite de intentos posibles. Hasta la vista baby!!!");
    break;
  } else {
    ingresar_clave = prompt("Clave incorrecta! Intente de nuevo.");
  }
}
if (contador < 3)
  document.write("<h2>Bienvenido. Su password " + password + " es correcto! </h2>");

Your counter must be inside while cycle and contador must be less then 3. Better way for this code wiil be using of do .. while.

var password = 'cometa';
var contador = 0;
alert('Ha sobrepasado el limite de intentos posibles. Hasta la vista baby!!!');

do {
  ingresar_clave = prompt ('Clave incorrecta! Intente de nuevo.');
  contador += 1;
} while (ingresar_clave !== password && contador < 3)

document.write('<h2>Bienvenido. Su password ' + password + ' es correcto! </h2>');
