Every time you open the Taxonomic Editor a log-in pop-up box will open. It allows changes to be tracked if there will be multiple users of the underlying CDM data store and you need to track changes. There are currently no authorization mechanisms in place and the login is therefore solely for authentication. Each user can log in under their own account.
Tip! A CDM datasource will have a user named admin with password '00000', so you can login immediately. The default password should the be changed.
