Password length requirements control how long a password must be for a NIOS appliance admin account. Increasing this value reduces the likelihood of hackers gaining unauthorized access.
To change password length requirements:
From the Grid tab, select the Grid Manager tab, and then select Grid Properties -> Edit from the Toolbar.
In the Grid Properties editor, select the Password tab.
Enter a number from 4 to 64 in the Minimum Password Length field.
Save the configuration and click Restart if it appears at the top of the screen.
