Your Similarity Check administrator account

Once Turnitin has enabled your Similarity Check account, as the main editorial contact provided on your application form, you become the Similarity Check account administrator. As an administrator, you create and manage the users on your account, and you decide how your organization uses the iThenticate tool.

This page explains how to set up your personal account and find your way around if you’re using iThenticate v1. If you’re using iThenticate v2, go to the Turnitin website instead.

iThenticate v1 or iThenticate v2?

There are now two versions of iThenticate available. Most subscribers are on v1, and the instruction on this website explain how to set up and use v1. Some new subscribers can start using v2 from September 2021 - we’ll let new subscribers know if v2 is appropriate for them when they apply. You can find out more about iThenticate v2 on our blog.

To work out which version you’re on, take a look at the website address that you use to access iThenticate. If you go to then you are using v1. If you a bespoke URL, https://crossref-[your member ID] then you are using v2.
