Hi @haidersheikh029,
Customers can register using either a mobile number or an email address in WooCommerce, but this requires some customization. The simplest approach is to use a plugin like Registration & Login with Mobile Phone Number. These plugins allow you to customize the registration form, enable phone number login, and add OTP verification for security. You can easily set them up in WooCommerce → Settings.
For a fully custom solution, you would need to modify WooCommerce’s registration fields and login process. Since custom coding is beyond our support scope, we recommend consulting a WooCommerce expert or hiring a professional from Codeable.io for assistance.
