Unauthorized: authentication required docker login

Trying to get my system up and running. When I get to sudo docker login nvcr.io , [sudo] password is accepted, username: I try my email and password but I receive Error response from daemon: Get https://nvcr.io/v2/: unauthorized: authentication required.
How or where do I get authorized?
I’ve been playing and replaying “nvidia Jetson nano 2gb first impressions by Dennis Faucher but it seems like he skips this step.

Hi,

You can find the account and password in our NGC page.

Setup -> API Key -> Generate API Key

Thanks.
