On April 3, 2025, the graphical interface of the login page to the OTE system (in the Sandbox test environment) was updated, along with modifications to the Registration section, which primarily serves for user account management. The aim of these changes is to improve user-friendliness and make the interface more intuitive.

Detailed manuals describing the new interface will be available soon. A shortened guide for user account management is already available here.

Please note that the same change will also be deployed in the production environment during the planned maintenance on April 22, 2025.

Thank you for your understanding.
