User accounts and password management on the NextSeq 1000/2000

Background

The NextSeq 1000/2000 Linux Operating System (OS) has three accounts:

• root (super administrator)

• ilmnadmin (Administrator)

• ilmnuser (User)

The ilmnadmin Administrator account is intended only for applying system updates such as updating the 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 root user account should not be used for any purposes other than emergency access.

The Field Service Engineer (FSE) initiates a password change for all three accounts after completing instrument installation and the user will be required to update each password. Update each password every 180 days according to the following policies when prompted by the Linux OS.

Policy	Setting
Enforce password history	Five passwords remembered
Lockout threshold	Ten invalid login attempts
Minimum password length	Ten characters
Minimum character variety	Three each of: number, upper case letter, lower case letter, and symbol
Maximum repeating character	Three characters
Password must meet complexity requirements	Disabled
Store passwords using reversible encryption	Disabled
