In my online checkout process I, like many checkouts, have a field for the customer's email address along with a field to confirm the email address. They are both identical text boxes and accept email addresses. They are both also mandatory.
I have code in place that prevents the user from copying from the Email Address
field to the Confirm Email Address
field. My questions is - is this bad UX or is this a legitimate way to attempt prevention of an email address being enter incorrectly once and pasted into the next field?
