-This code provides the following functionality:
-
-1. **Login Endpoint**: `/token` endpoint to authenticate a user and return an access token. The token is stored in a browser cookie.
-2. **User Endpoint**: `/users/me` endpoint to fetch the current authenticated user's data using the access token.
-3. **JWT Implementation**: JSON Web Token (JWT) implementation for generating and verifying access tokens.
-4. **Password Hashing**: Password hashing and verification using the `passlib` library.
-5. **Helper Functions**: Functions for user authentication, password verification, token generation, and getting the current user from the token.
-6. **Data Models**: Pydantic models for Token and TokenData.
-
-Note: This code uses a fake user database (`fake_users_db`) for demonstration purposes. In a real application, you would replace it with an actual database implementation.
