Final answer:
The configuration to deactivate a patient account after a specific number of failed login attempts is usually set in the security settings section of the masterfile in the software system.
Step-by-step explanation:
In most software systems, the setting to deactivate a patient account after a certain number of failed login attempts would typically be found in the security settings section of the application's masterfile. The masterfile typically includes configurations and options that govern various aspects of the application's operations, including security protocols. To set up automatic deactivation for a patient due to failed login attempts, one would navigate to the security settings within the masterfile, find parameters related to account lockout or login attempt limits, and configure the desired number of attempts before the system automatically deactivates the patient account.
