Reply To: Show/Hide Password icon in login and register forms

Hello,

Login/Register is the Woocommerce functionality. Woocommerce does not have such functionality by default: https://themes.woocommerce.com/storefront/my-account/
Please make the full backup of your site as well as the Theme settings export and check the issue on the Storefront theme to detect if our theme causes the problem.

Best Regards
