title: How to automatically keep user remembered in Devise
body: <p>I am building an app in which I would like the users to automatically be remembered on their computers, without having a "remember me" check box.</p>
  
  <p>I read that I may have to call <code>@user.remember_me!</code>, but not sure where to call it since the Devise controllers are hidden.</p>
  
  <p>I was considering adding a hidden checkbox field in the sign_in form with the checkbox marked by default, but I was hoping I could do this on the controllers side.</p>
  
  <p>Any idea how this could be done?</p>
  
  <p>Thanks!</p>
