External authorization on the blog

I want to create a blog on my domain. https://mysite.com/blog/
And I want users who log in to my site to immediately get access to editing on the blog.
Question: is it possible to have authorization on my site and at the same time not force users to authorize a second time on the blog?

To clarify, you’re saying you have your own auth layer in front of Ghost, and you want these users to be able to access the admin interface once they’ve logged into your auth layer?

The first thing to note is all users with access to the admin interface are considered fully trusted, so be careful who you give access to.

You could probably use Ghost’s session based authentication as part of your auth flow
