User Account Requirements

The Linux operating system has the following accounts:

• root (super administrator)
• ilmnadmin (administrator)
• ilmnuser (user)

The administrator account is intended only for applying system updates, such as updating NextSeq 1000/2000 Control Software, or for use by IT staff to mount a persistent network drive.

Perform all other functions, including sequencing, from the user account.

The Illumina Field Service Engineer initiates a password change for all three accounts after completing instrument installation. Update each password every 180 days, when prompted.

This section describes how to reset the ilmnuser, ilmnadmin, and root passwords. Password recovery is not available. Resetting your password does not bypass account lockout after 10 incorrect password attempts. You must wait 10 minutes before you can reset your password or try to log in.
