Hi richard-3388,
Thanks for reaching to us and appreciate your patience.
There are few settings of Login / Registration in WooCommerce > Settings > Accounts.
Meanwhile, Login and Registration are default WooCommerce functionalities and WoodMart does not control it. For specialized assistance and potential solutions, I kindly suggest that you reach out directly to WooCommerce plugin support on the plugin support forum https://wordpress.org/support/plugin/woocommerce/, who are better equipped to provide you with the guidance you requires or You need to find a third party plugin to achieve more functionality that best suits you.
Regards,
