So, I Have uploaded my web app, built on express on Heroku. Temporarily there are four app users, so I went on my deployed website and logged in my id, then my friend with his device went to the link and was directly logged in with my id, like it was pre logged in. I think the deployed server is storing the app.currentUser() when anyone logs in the server.
I think the problem is with this file, even though i have added this file in .gitignore it still shows up.
Thank you in advanced!
