EF with dynamic database password

Question

I'm working on C# MVC 5 app that each user must username, password, server, and database to connect.

For each user, the authentication DLL will provide a unique connection string. The password works only for one user during a section time. Each user has different permissions on tables.

Answer 1

Where is the question? If you need to change connection string do it in Context.Database.Connection.ConnectionString, then call Open. It should be work.

Answer 2

using MVC 5 Controller with view, using EF .. ( make sure you have model and view like CRUD system) and if you want each user have unique connect , using guid();
