Is it possible to have Lock display a username popup format guide or hint tooltip to the user, similar to how it displays a password format guide, while the user is typing?
We would like to guide our users on how they should be selecting a correctly-formatted username.
Unfortunately we do not offer that same popup functionality for the username/email field. You can however update the text that populates the username input field which you could use to show a properly formatted username. Information on that can be found here:
