Recover password in PHP

I made a simple system to recover password. The system is working normally, but when the user clicks on the confirmation email, his email appears in the URI, what do I do? Here is the code:

This is the html form:

<section class="recipiente margem-topo-100">
    <form action="recuperar_por_email.php" method="post" class="coluna">
      <input type="text" name="recuperar-senha" placeholder="Insira seu email">
      <button class="icones icone-enviar"></button>
    </form>
  </section>

This is the code that sends the email and creates the variables I use:

<?php

  require_once "PHPMailer/PHPMailerAutoLoad.php";
  require_once "interno/conecta.php";
  require_once "interno/funcoes.php";


  $recupera = $_POST['recuperar-senha'];
  $link = "http://localhost/toqve/recuperar.php?recupera=".$recupera;

  $mail = new PHPMailer();

  $mail->IsSMTP();
  $mail->isHTML(true);
  $mail->CharSet = 'utf-8';
  $mail->Host = 'mx1.weblink.com.br';
  $mail->Port = 587;
  $mail->SMTPSecure = 'tls';
  $mail->SMTPAuth = true;
  $mail->Username = '[email protected]';
  $mail->Password = '*********';
  $mail->setFrom("[email protected]", "daLvz");
  $mail->FromName = 'daLvz';
  $mail->Subject = "Recuperar senha";

  $mensagem = "Clique <a href=".$link.">aqui</a> para recuperar sua senha. 

  $mail->Body = $mensagem;
  $mail->AltBody = "Conteudo do email em texto";

  $mail->addAddress($recupera);

  if($mail->Send()) {

    header("Location: confirmacao.php");
  } else {

    echo "Erro ao enviar email". $mail->ErrorInfo;
  }

This is the page that appears when the user clicks on the received email:

<?php

  require_once "cabecalho.php";
  require_once "interno/conecta.php";
  require_once "interno/funcoes.php";
  $recupera = $_GET['recupera'];
?>

<section class="recipiente margem-topo-100">

  <form class="coluna" action="sucesso.php" method="post" >
    <input type="text" name="recupera" value="<?=$recupera?>">
    <input type="password" name="senha" placeholder="insira uma nova senha">
    <button class="icones icone-enviar"></button>
  </form>
</section>

Can anyone help me? Thanks!
