Login via code in addition to the link for the E-Mail Authentication
Today the E-Mail Authentication only has the option of logging the user in via a link in the E-Mail. This restricts the user to logging in on a computer where they have an e-mail client of which excludes most kiosk solutions and makes it a hassle if the user usually uses their e-mail on for example their phone but uses Primo on another computer.
Adding the option of logging in via a code (in the same e-mail) which the user can enter on the device where the user initiated the login process rather than the device where the user read the e-mail solves this problem rather simply.
