e commerce - Preventing a user from pasting from the clipboard into a mandatory form field


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?



Answer



If you feel the 'Confirm Email Address' field is required, but want to prevent people copy-and-pasting it then why not take a different approach?



When requesting the user details and email address just ask the questions once. Then, on the final sign-up / payment screen (depending on your application) add a field on this last page stating:



"We will send your confirmation to: _______"



pre-populated with the email address entered earlier, but as an editable field so they can amend it if it was entered wrong before.


This provides another opportunity for the user to evaluate their entry without just blindly cutting-and-pasting, and because you're informing them that you will be sending something specifically to that address they would possibly take more time to read it to ensure it is correct.
