Getting a login account

To login to an NSC resource, you need a login account. Please note that login accounts are created separately for each NSC resource. For example, you do not have a login account on Tetralith just because you have one on Sigma.

For login accounts on dedicated SMHI resources such as Bi, please refer to SMHI access. The rest of this page does not apply in that situation.

To get a login account on a resource, you need to:

• Accept the User Agreement
• Become a member of a project
• Request the login account
• Choose password for the login account

Each step is described in more detail below.

Accept the User Agreement

You need to have accepted the NAISS User Agreement. Once is enough; you do not have to do this again if you want further NSC accounts or accounts at other centres.

To take care of this, login to SUPR and use the "Handle User Agreement" button on the top of the page. If you have already accepted the NAISS User Agreement, you will not see the "Handle User Agreement" button. You can check the status on the SUPR Personal Information page.

If you have accepted the SNIC User Agreement before, you will be able to accept the NAISS User Agreement online in SUPR (even if you did the SNIC User Agreement via the paper alternative).

Depending on how you take care of the NAISS User Agreement, it may be approved automatically or it may require manual checking (for example if you choose to use the paper alternative). You will get an email from SUPR when it has been approved.

Note: if you have accepted the NSC-specific User Agreement earlier (when getting another login account before this was moved to SUPR) and you cannot easily get the NAISS User Agreement handled, please email us at .

Become a member of a project

See the information about becoming a member of a project if you have not already taken care of that. The project needs to have time allocated (now or in the future) on the resource you want a login account for.

Request the login account

You need to request the login account, as we do not automatically create login accounts before we know that you are going to use it.

Note: You can request login accounts before the User Agreement and the project memberships have been approved, but the requests are not handled until they are approved.

Login to SUPR and go to the Accounts page. You will see the login accounts you already have at NSC and other centres. Under the "Possible Resource Account Requests" headings you find the NSC resources you can apply for login accounts on. Just use the "Request Account on Clustername" button and confirm it on the next page.

Checking your request and approving your account requires some manual work, so you might have to wait for some time (up to a working day) before the next step.

Choose password for the login account

When the account is ready to be created, you will receive an email to your registered email address (shown in your SUPR contact information) with information on how to proceed.

For Tetralith, Sigma, and Berzelius, you will get a URL that you use to choose the password (within seven days) and enable two-factor authentication ("2FA"). When that has been done, the account ready for use within 10 minutes and you can then login using your chosen password.

For Bi and Nebula, you will get a URL that you use to choose the password (within seven days). When that has been done, the account ready for use within 10 minutes and you can then login using your chosen password.

For other clusters (e.g Cirrus and Stratus), you get an email with your username and preliminary password. You then login using SSH as soon as possible (within seven days) to set a new, unique and good password.

Always use a unique password for each login account!

It is better to use a long password, for example four or more random unrelated words with a number or special character inserted somewhere, than to use a short or commonly used password or a password that a computer could guess.

It is recommended to use a password manager to allow for strong passwords instead of picking passwords that are easy to remember. As requirements and needs vary between different individuals and organizations, we cannot recommend any particular product. Please take care to properly research any such product before use.

Once you get your login account, check our support pages if you need help to get started.
