How to find duplicated user accounts

We think that some of the users might have created more than one account. We have come across an author who is also a reviewer and who has two accounts. How can we identify duplicated user accounts / double entries?

ConfTool Pro comes with a function that checks for users who registered or were entered more than once in the ConfTool system.

Please call this page:
Overview => User and Participant Management => Find Duplicated User Entries
The system will search for similar names (first name and last name combinations) and matching e-mail addresses to create a corresponding output (see image).

The results will be categorized (see image):

• Similar users found: The names seem to be very similar. Please check manually whether any of the names simply were misspelled or if these are entirely different users.
• Exact name match found: Please check whether these are different users with the same name or if a user has two different user accounts. Usually, the user statuses will give you some hints, too.
• Warning! Duplicated e-mail found: The system found two accounts with similar or exact name matches and a duplicated e-mail address. As the e-mail address also serves as an identifier in the system (for instance to identify user accounts of co-authors), please make sure that each user has a unique e-mail address.
