How do I reset credential on AWS Elastic Beanstalk

I accidentally typed in the wrong aws-access-id and secret key after running eb init when going through the tutorial Deploying an Express Application to Elastic Beanstalk

Now I am getting the following error "Error: "my-mistyped-key" not a valid key=value pair (missing equal-sign) in Authorization header..."

What is the best way to reset my credential so that I can run "eb init"
