The login process is depicted in a UML sequence diagram as the back and forth between a user and the system. This starts when they enter their username and password which gets validated by the system. In case of correct credentials, the system provides access and takes the user to his/her dashboard; while in case of incorrect credentials, one access is denied prompting them to re-enter their credentials.
Thus, it outlines stepwise procedures that help maintain safe yet easy ways of confirming identity. This helps ensure that unauthorized personnel do not get access to the system.
