From the Company Settings section, on the left hand side, click on Security. There is a toggle under "General Settings" to disable account login. Simply click on this setting to enable this feature. See figure 1 below for a screenshot of the toggle on the Security tab of the Company Settings page. If this Company Setting is enabled, then every night a Dash process will go through all accounts and disable any that have not met the login criteria.

To re-enable a Dash user account simply go to the User page and reset the toggle to be enabled. See figure 2 for a screenshot on how to enable the toggle.
