If you have been able to log in earlier, or you have taken part in a project at NSC, or you receive the "NSC News" newsletter to your personal address, please send an email to firstname.lastname@example.org and ask us to help you get access to your NSC Express user.
If you are going to use SNIC or LiU resources, you should register in SUPR first. An NSC Express user will be created for you based on the SUPR user the first time you become member of a project with allocation at NSC. You will be able to login to NSC Express using your SUPR user.
Only if none of the above applies to you, proceed to create a new user in NSC Express.
