How to Log into AWS

We use Leapp to facilitate logging into AWS. Leapp is a tool that allows you to authenticate with your organization's Identity Provider (IdP) and then assume an IAM Role in AWS. This allows you to use your organization's SSO to authenticate with AWS.

Install Leapp following Leapp documentation or with brew:

brew install --cask leapp

2 Install AWS Session Manager (If required)​

brew install --cask session-manager-plugin
