I am building a web server that will accept requests from mobile devices and route to 2 different SQL Server instances. For extra security, I want the mobile devices to have to log in twice - log in to the web server and then log in to SQL Server.
If I'm using ExpressJS (with Typescript), where/how would I store the web server logins? Would I use some npm package or something?
This web server might be hosted on Azure - would Azure have a way for me to create a database to store web server logins?
