Similarity Check: look out for a refreshed interface and improvements for iThenticate v2 account administrators

In 2022, we flagged up some changes to Similarity Check, which were taking place in v2 of Turnitin’s iThenticate tool used by members participating in the service. We noted that further enhancements were planned, and want to highlight some changes that are coming very soon. These changes will affect functionality that is used by account administrators, and doesn’t affect the Similarity Reports themselves.

From Wednesday 3 May 2023, administrators of iThenticate v2 accounts will notice some changes to the interface and improvements to the Users, Groups, Integrations, Statistics and Paper Lookup sections.

Logging in

iThenticate v2 account administrators and browser users will see a new login page when logging in to iThenticate v2:

A refreshed interface

Once logged in to iThenticate v2, account administrators will see an updated design, with improved notifications to let them know whether a task/action has been successfully completed or not.


There will be improvements to the user management system for account administrators, including a much clearer navigation menu for managing active, pending and deactivated users.

There will also be a filtering option on the Users page to search for active, pending and deactivated users by first name, last name, email address, group and date added. In addition coloured labels will be introduced to easily identify the level of access (or ‘Role’) for each user.

An improved bulk user import process will be available, with clearer guidance on any issues that may arise during the upload. This new development will also include new screens for adding and editing users with more notifications to help prevent mistakes.


For account administrators managing peer review management system integrations and needing to generate API keys, the Integrations page will be improved to make copying API keys simpler.

iThenticate v2 administrators will also notice some improvements to the Statistics page. Usage data should load faster and will be sortable by user group. They will also be able to generate large usage reports of over 100k submissions.

Paper lookup

The Paper lookup will allow iThenticate v2 account administrators to find submissions that have been made from any integration connected to their iThenticate v2 account. They can be found by searching the paper ID (or oid number) of the submission.

Please note: the ability to search for submissions by the user’s name is available for manuscripts submitted via the iThenticate v2 website only and not for papers submitted via an integration.

New password requirements

To improve the security of users’ accounts, new password requirements will be introduced, including a minimum of 8 symbols, 1 special symbol, 1 upper case letter, and 1 number.

Next in iThenticate v2

Turnitin, who produce iThenticate, are currently working on a number of new features and developments including an improved similarity report, paraphrase and AI writing detection. A detailed timeline is not yet available but we’ll be updating you on these new developments in the coming months.
