Quto login from inside another APP

I have a secure database business management software. I want to add a link inside the software to a tutorial website. The website is private and people need a user name and password to login from the internet. But I don’t want to have to give all my database users a userid and password to log in to the tutorial website if they are inside the database working. Is there a way to set up a link that functions as an auto login so my database users can go directly inside the tutorial website without having to sign in?
