+

+
+The full path should be "app/views/devise/two_factor_authentication/show.html.erb"
+
+```html
+<h2>Hi, you received a code by email, please enter it below, thanks!</h2>
+
+<%= form_tag([resource_name, :two_factor_authentication], :method => :put) do %>
+  <%= text_field_tag :code %>
+  <%= submit_tag "Log in!" %>
+<% end %>
+
+<%= link_to "Sign out", destroy_user_session_path, :method => :delete %>
+
+```
