The new API by Fidelity Investments called Fidelity Access will give third parties access to customer data; the idea behind the program is for customers to give apps focused on tax prep, budgeting or portfolio advice access to their Fidelity data; Fidelity believes this will cut down on cyber crime as access will be more secure instead of a user passing along their credentials; they are following a number of other financial institutions who have started similar programs recently.
