This post has been here a while, but I think I can help. As far as I know there is no way for Postman to imitate user logins.

I would suggest writing your own tests using Selenium or Puppeteer. There is a great Chrome extension called Selenium IDE that can record how you interact with your site and generate tests based on it, I think that would be a good start.

Hope this helps, cheers 🍻
