How to automatically login to Google OAuth for one Google Blogger account holder

I am trying to grab the latest posts from my google blogger account and integrate them into my site. I have been playing around with google OAuth lately to get an access token to get my messages using ajax requests. However, in order to get the access token, I had to open a window for google and manually register each time.

Is there a way for my site to automatically login to google with my credentials, get an access token, and make an ajax request to get the latest posts from my blogger account?

Also is this possible with javascript only?

I want to display some of my blogger posts on my site without displaying the google blogger page.
