Authentication system

This section works with tables: external_user and internal_user.

Option card:

User Authentication

1. Precondition: The user has registered and is in the table of external or internal users
2. Guarantee: an external user has registered and gained access to the user menu, an internal one - to the role
3. Minimum guarantee: the system has reported an unauthorized authorization, the user must enter the password again or log out

End User Scenario:

1. The user starts the authentication process
2. The system sends a form for login and password
3. The user enters the login and password for access
4. The system opens access that corresponds to its role

Exceptions:
- the user entered an incorrect username and password or did not enter them → item 2.
