#     - Story 2:
#      - As a user, I want the sign-up form to include a CAPTCHA verification step, so that the system can prevent automated bots from creating fake accounts.

#      - As a user, I want the sign-up form to include optional fields for additional profile information, so that I can customize my account based on my interests.

#     - Story 2:
#      - As a registered user, I want the login page to feature a "Forgot Password" link, so that I can easily initiate the password recovery process if needed.
#     - Story 3:
#      - As a user concerned about account security, I want the platform to send a notification email whenever my account is accessed from a new device, so that I can be aware of any potential unauthorized access.
#     - Story 4:
#      - As a returning user, I want the option to enable two-factor authentication (2FA) for an extra layer of security during the login process, so that my account remains protected.
#     - Story 5:
#      - As a user striving for a seamless experience, I want the platform to offer a "Stay Logged In" option during login, so that I don't have to enter my credentials every time I revisit the site.
