New user accounts are created with the option button:
The user name needs to be specified during user creation, but can be changed later using the Edit user name button. This name will be attached to data saved in a database and can be used in data filtering.
Note that no user passwords are required in the standard PMOD usage, since the accounts are rather aimed at separating the processing environments for different tasks than protecting data access. Only in the case of an ATL version which is aimed at controlled data processing, are passwords enforced.
