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