## Purpose

Allows an existing user to access the Creditor Portal.

## How It Works

User enters:

* Email
* Password
  System authenticates credentials.

## Result

* User is logged in
* User is routed based on account status

## Validation Rules

* Email must exist
* Password must match
* Email must be verified

## Failure Scenarios

* Invalid credentials
* Unverified email
* Inactive account

## Developer Notes

* Use secure authentication (session or token based)
* Normalize error responses
* Implement rate limiting and brute-force protection
* Return user state flags
* Routing logic should be determined by backend state
