I am new to Heroku and MongoDB. I created a Heroku app which has an added-on MongoDB by MongoLab.
Everything was set up automatically by Heroku. When I navigated to MongoLab database manager page (SSO protected) it showed a standard MongoDB URL as:
mongodb://<dbuser>:<dbpassword>@dsxxxxxx.mongolab.com:39674/heroku_xxxxxxxx
Those "x" letters represents numbers.
I didn't bother to specify a dbuser and dbpassword at all. So what is the dbuser and dbpassword?
