Create a Login Page

WooCommerce does not have a separate Login shortcode. Instead when visiting the  My Account page as a guest you will be presented with a login form.

1
Create a new "My Account" page and add the [woocommerce_my_account] shortcode to the page.
2
Visit  WooCommerce → Settings → Accounts and choose the page you just created in the My Account setting.
