Enable WordPress Auto-Login

You may also think that loggin in every time you want to access the admin area of one of your WordPress blogs is quite annoying. But there is a quick way to enable the auto-login for WordPress. It’s shown below.

Add the following lines of code to the functions.php in theme directory:

function auto_login() {
  if (!is_user_logged_in()) {
  //determine WordPress user account to impersonate
  $user_login = 'guest';
 //get user's ID
  $user = get_userdatabylogin($user_login);
  $user_id = $user->ID;
  //login
  wp_set_current_user($user_id, $user_login);
  wp_set_auth_cookie($user_id);
  do_action('wp_login', $user_login);
  }
}
add_action('init', 'auto_login');
