Develop a .Net Core Authentication Site

Below is an overview of what is required for this project. However, a full requirements document is attached and must be reviewed for accurate bidding. This is a module for a larger project.

UI and UX will be done later) * Create and wire up MSSQL database tables * Written with .Net Core 5 language * External provider authentication: Integration with Facebook, Google, and other external authentication providers and linked to an internal profile (OAuth 2.0) * Internal provider authentication alternative: new user can create a sign up (Fields will be supplied, email verification) * User sign in (ability to remember user * User log out * Password is salted independently for each user (salt field) * DB Connection, Email Connection, other items must be configurable * Modular design allowing for a basic framework to be put together to be shipped to other developers who will work on other pieces of this project.
