Hide custom field when user logged in

Hello,
i use a custom field in registration form for informing users for saving they username and password for further utilisation.
(Some users with pay later option forget they have make a username and password...)

But if a user is logged in, i want this field not showing.
Is there a way to do that, for example, with a coding in extra field ?

Regards,
Frédéric

Edit the field, set Access to Guest and it should solve the issue
