Registering using email only?

Just like WordPress/Woocommerce standard registration process, I want my customers to register using an email only and the password automatically generated. It just makes things easy for users.

Is there anyway to remove the ability for new users to choose a Username and password?

We are having a lot of users getting errors because they can’t choose the username they want.

This very important and I would really appreciate the help.
