OTP for magento 2ecomerce site

Like to attach OTP module in my Magento2 web site. It should authenticate, mob number, email address in registration for client, sellers and admin employees, at payment or check out, forget pass word, and other functions available in my bought OTP module.This will also include all other functionalities such as Twlio integration. Needs at least 6 weeks post handover support. Project needs to be completed in 2-3 weeks. Teach my employee to handle the functioning such as stopping or initiating the functionalities of the module. Payment will be at the handover of the project.
