The student starts the client application and is met with the login screen, shown in the figure below:
The username field represents the student's Cal Poly (or any other school's) portal username. The password represents the student's password that he/she uses to log in to the system. The student fills in both fields and clicks "Log In" to continue to the next screen.
Before logging in, the program checks the student's credentials against the school's system. Once the credentials are verified, then the student continues on to the next screen. If the credentials are not correct, the program asks the student to re-enter their credentials until they are correct.
