-Finally you need to request login accounts to NSC and UPPMAX. These are the accounts you use to log in to the actual computers, so they are not the same as your SUPR account. Login to SUPR and go to the [Accounts page](https://supr.naiss.se/account/). Under the **Possible Resource Account Requests** heading click on **Request Account on Tetralith @ NSC** and **Request Account on Rackham @ UPPMAX** button and confirm it on the next page. If either of them are missing from this page, it could be because you already have a login account created (only 1 account per person allowed), or that you have not yet gotten your project memberships approved.

 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. 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. You will get a one-time URL that you use to get the password (within seven days) to login to the cluster with. The link is only valid for 1 visit, so write down the password you get. When that has been done, the account ready for use within 15 minutes and you can then login using your password. Once you have logged into the cluster you can change your password by typing `passwd` in the terminal and follow the instuctions.
