Starting on September 21, 2018, we updated the overall security of the NDS suite. Users that fail to correctly enter their username and password several times many now be presented with a identity challenge before continuing to login. It looks like this:
This security improvement is to prevent automated systems/actors (also known as bots) from gaining unauthorized access to NDS. In order to complete the verification process, click the checkbox "I'm not a robot".
Some users may be presented with an additional challenge. You will be served up several images and asked to complete a simple task, such as "select all the images with cars."
Answer the prompt by selecting the correct images and clicking "verify".
If you have any additional problems accessing your account, please reach out to the Helpdesk.
