You can use hook_form_FORM_ID_alter in your custom module and change the weight of the links

function MYMODULENAME_form_user_login_block_alter(&amp;$form, &amp;$form_state){
  $form['links']['#weight'] = 100; //define weight as such the links moves below  submit button.
}


Replace "MYMODULENAME" with the name of your custom module.
