User Login (UML State Machine Diagram)
A state machine diagram is a visual representation of the different states that a system or process can be in, and the transitions between those states. In the context of a login process, there are several different states that a user may experience.
The initial state in a login process is when the user has not yet entered their login credentials. From this state, the user can transition to the "credential entered" state by entering their credentials and submitting the form.
If the login credentials are correct, the user will transition to the "successful login" state. In this state, the user has successfully logged in to the system and can access the various features and functions that are available to them.
However, if the login credentials are incorrect, the user will transition to the "incorrect login" state. In this state, the user will be prompted to try again, either by re-entering their login credentials or by resetting their password.
If the user continues to enter incorrect login credentials, they may eventually reach the "locked out" state. In this state, the user has entered incorrect login credentials too many times and has been locked out of the system for a period of time. Once the lock-out period has expired, the user can transition back to the initial state and try logging in again.
