# Page: Authentication and Login

## Purpose

This page explains how users sign in to the admin portal and how authentication affects access to fraud and AML features.

## Sign-in process

1. Open the login page.
2. Enter the registered email address.
3. Enter the password.
4. Click the Sign in button.
5. After successful authentication, the portal loads the home or dashboard page.

## What authentication controls

Authentication determines:

- whether the user can access the platform;
- which menus are displayed;
- which workflows and records the user can view or edit.

## Example usage

Example: an investigator logs in with their analyst account and is shown the fraud menu. A user with a limited role may see only the pages relevant to their responsibilities.

## Common issues

- Invalid credentials: check the email and password.
- Session expiration: sign in again if the session has timed out.
- Missing menu items: confirm the assigned role and permissions.

## Notes

Authentication is the entry point to the entire system. If a user cannot sign in or cannot access a page after signing in, the issue is usually related to credentials, session state, or assigned permissions.
