Interactive configuration If you have the AWS CLI, then you can use its interactive configure command to set up your credentials and default region: It is not a portable solution. The mechanism in which Boto3 looks for credentials is to search through a list of possible locations and stop as soon as it finds credentials. The order in which Boto3 searches for credentials is: Passing credentials as parameters in the boto.client () method Passing credentials as parameters when creating a Session object Environment variables Shared credential file (~/.aws/credentials) AWS config file (~/.aws/config) Assume Role provider
