autocomplete="email" without email confirmation input

I am implementing a "login with email" feature i.e. the user enters her email address, I then send them a link, when the click it I authenticate them.

I would like Safari to autofill the email address for the user but it always treats it as a username (but never gives the option to save the username). So basically Safari prompts the user to use a username from another website, instead of autofilling their email address in the email input.

However if I ask the user to enter their email and display another box to confirm the email address, Safari correctly autofills the email.

Is there a way to autofill a single "email" field on a form?

Thanks
