Auto fill-in username + password when user clicks a website link

_x000D_ _x000D_ I am currently building an intranet site and on this site, we have websites people would frequently use. There are a couple of websites where people need to login though. So I was wondering if there is a way to automatically fill in the username and password box on that website when the user clicks the link for it. The login info will never change and all users have to use the same login. Something that automates this process would make things easier for the user. So in my aspx, I would have something like this (not this exact website but a different one): Litmos
I'm not sure if I need to use the code behind to do what I want or maybe some Javascript. The type of functionality I am looking for is like the one found in KeePass. Where you enter your username and password along with a website url and when you open that website from KeePass, it fills the login info for you. I realize that that is a desktop application and I'm building an ASP.NET website. I want to know if something like this is possible and if so, how. Just so you know, I'm using C# for the code behind for the intranet site.
