How to change the Linux OS passwords on the NovaSeq X Series Instruments

The Oracle 8 Linux Operating System (OS) on the NovaSeq X Series has two accounts:

• ilmnadmin (Administrator)

• ilmnuser (Standard User)

The administrator account is intended only for applying system updates and updating passwords. Perform all other functions, including sequencing, from the ilmnuser account.

To reset the ilmnuser password from the ilmnadmin account:

1. Log into ilmnadmin.

2. Select the Activities menu in the top left corner, then open the Terminal.

3. Enter the command: sudo passwd ilmnuser

4. Enter the ilmnadmin password at the prompt.

5. Enter a new ilmnuser password at the prompt.

6. Retype the new ilmnuser password at the prompt to confirm the new password.

If all passwords have been lost/misplaced, contact Illumina Technical Support for further guidance.
