Using email as username

-- HikaShop version -- : 6.1.0
-- Joomla version -- : 5.3.3
-- PHP version -- : 8.4

Hi!

Is there any option to active a feature that makes the email address of the customer = username or hides the username?

Most webshops in the world offer only email address and password as account credentials. But Hikashop want to create an email address AND a username. This is very uncomfortable for most users / customers. It would be a very useful feature if we could turn off the need of the creation of a username. Alternativly HikaShop should use the email address internally as username - if the username is needed.

What do you think?

P.S. In the meantime I made a little workaround: renamed the language strings and so we use technical the email as username.
