Odoo Application - 2FA Two Factor Authentication, Product Lot Split Function, and Accounting Setup

We need an odoo developer to do the following: 1. 2FA - Setup a Two Factor Authentication for our Odoo system 2. Product Lot Split Function - develop an odoo application or function that would let the user open a product lot and split it to corresponding product. For example, there are 2 product entries: Product A and Product Ax5. Product Ax5 is a product lot of Product A (5 Product A packed as one). When Product Ax5 is opened, it should be split into 5 Product As. Inventory should be updated accordingly: Product Ax5 inventory should decrease by 1 and Product A inventory should increase by 5. 3. Accounting Setup - We're pretty sure this is already working in odoo, we just need someone to help set the chart of accounts. We just need to setup all the accounts so the accounting reports would be complete. Like for example, every time a product is sold, the cost of goods sold or cost of revenue derived from the product cost should be accounted and shown in the report Thanks!
