It's recommended The order in which Boto3 searches for credentials is: In your case, since you are already catching the exception and renewing the credentials, I would simply pass the new ones to a new instance of the client like so: If instead you are using these same credentials elsewhere in the code to create other clients, I'd consider setting them as environment variables: The session key for your AWS account [] is only needed when you are using temporary credentials. @JimmyJames the use case for STS is that you start with. To pass AWS credentials to the Boto3 client, you have to provide them in the aws_access_key_id and aws_secret_access_key variables, for example: Passing AWS credentials to boto3 client import boto3 client = boto3.client ( 'iam', aws_access_key_id ="XXXXXXX", aws_secret_access_key ="YYYYYYY" ) How to specify AWS Region in the Boto3 client? # This is because we've provided an invalid API version.

It uses the same code from boto3 (botocore, actually) that the assumed-role-profile setup uses. This creates a pre-configured credential resolver that includes the default lookup chain for credentials. The only difference is that profile sections must have the format of [profile profile-name], except for the default profile: The reason that section names must start with profile in the ~/.aws/config file is because there are other sections in this file that are permitted that aren't profile configurations.
