Adding a copy link in the email to copy the verification code

Question

As part of sign up, I want the user to verify their email by copying the verification code from the email that has been sent to their personal email address, and then entering the code in the input screen to verify their email. Pretty standard.

However, on the email, I was thinking of incorporating a copy link next to the verification code. Which when clicked, copies the code and saves the user having to highlight the code themselves and then pressing copy. I think this link will be more helpful on mobile when copy and paste is a little more fiddly.

Example:

456873 copy

But I can not find this behaviour in other examples, is there a reason for not incorporating a copy button that I have missed? Or are there examples and I have not found them?

Answer 1

If you're sending via email, you can't use Javascript due to security reasons, so the copy code feature won't work.

For SMS or app-based communication (like on mobile devices), phones often recognize codes, and when prompted for entry, they typically display an option like "code_goes_here" for easy selection.

In short: For emails, this functionality isn't possible – that's the straightforward explanation.
