Restricted access to the application

You can restrict access to the application in the following ways:

Terminate a user.
Typically, you terminate users who leave the organization. Terminated users cannot log in. All users, including terminated users, remain in the study for audit purposes. Terminated users can be reinstated and then activated.
Inactivate a user.
Typically, a user is automatically inactivated when the user fails to log in after the number of attempts set on the System Configuration page. After the user account is inactivated, only an administrator can manually reactivate the user. The user must be reactivated before the user can work in the application.
