Creates a temporary AWS_ACCESS_KEY_ID
and AWS_SECRET_ACCESS_KEY
that can be used with command-line tools such as awscli
, ansible
, terraform
and more.
This method of authentication is preferred because it eliminates the need for long-lived access keys and forces every user to use their own credentials when connecting to AWS Services.

It is strongly recommended to use Okta Push Notifications for MFA if at all possible. Storing your Shared Secret or passing it in through the command-line comes with the risk of exposing the Shared Secret to unintended persons. If compromised, the security of MFA is lost. Please proceed with caution and an understanding of the risks associated. If you believe your Shared Secret has been compromised, please revoke it immediately.
An error occurred (AccessDenied) when calling the AssumeRoleWithSAML operation: Access denied
You likely have lost permission. Please try to sign in via AWS Console.
