You can manage the admin and audit user's account through an NSX-T appliance's CLI.
The admin user can manage the password and change the name of the admin and audit users, but cannot add, delete, or disable users. Any change to the admin or audit user's account will be audited.
The audit user has read privileges to the NSX-T environment and is not active by default. To activate it, log in as admin and run the set user audit password command and provide a new password. When prompted for the current password, press the Enter key.
By default, user passwords expire after 90 days. You can change or disable the password expiration for each user.
When the password of admin or audit on the NSX Manager will expire within 30 days, the NSX Manager web interface displays a password expiration notification. If you set the password expiration to 30 days or less the notification is always present. The notification includes a Change Password link. Click the link to change the user's password.
