What is Login flow in Laravel, and what role does it play in a real application?

What is Login flow in Laravel, and what role does it play in a real application? In Laravel, login flow should be understood as part of a larger application architecture rather than as an isolated API call. Authentication verifies credentials or another identity mechanism and establishes the user's authenticated state. A strong understanding includes its purpose, the layer where it belongs, the data or request flow it affects, and the situations where another mechanism may be more appropriate. Practical context: Authentication identifies the current user and maintains the authenticated state used by protected application workflows. The specific focus here is login flow: Authentication verifies credentials or another identity mechanism and establishes the user's authenticated state. This question is designed to test not only terminology, but also how the concept fits into Laravel's request, application, database, security, or deployment workflow.
