Flask-Login keeps track of the logged in user by storing its unique identifier in Flask's user session, a storage space assigned to each user who connects to the application.

SECURITY_CONFIRMABLE: Specifies if users are required to confirm their email address when registering a new account. If this value is True, Flask-Security creates an endpoint to handle confirmations and requests to resend confirmation instructions.The URL for this endpoint is specified by the SECURITY_CONFIRM_URL configuration option. Defaults to False.
