A method may include obtaining, from a user device, a request to access a control system among various control systems. The method may further include determining whether a user associated with the user device is authorized to access the control system based on user information associated with the user in a database. The method may further include generating, in response to determining that the user is authorized, a user code associated with a predetermined time period for accessing the control system. The method may further include transmitting the user code to the user device and the control system. The user code may authenticate a user session between the user device and the control system. The method further includes transmitting, in response to the predetermined time period expiring, a command that terminates the user session between the control system by the user device.
