Secure User Authentication | Enterprise iPad Application
The application is configured to operate exclusively on designated iPads, identified by their unique MAC addresses. The initial step in the authentication process involves verifying the device's MAC address. Upon successfully validating the MAC address, the system authenticates the user credentials. The user is prompted to input their username and password, which the system verifies. This two-tiered security protocol ensures robust protection against unauthorized access.
