An aws-adfs spinoff that fits BYU's needs
Project description
Python script for CLI and SDK access to AWS via ADFS while requiring MFA access using https://duo.com/
History and Purpose
BYU used to use the great aws-adfs CLI tool to login to our AWS accounts. It worked great, especially the DUO 2FA support. Eventually, we decided to write our own similar tool but make it BYU-specific so that we could taylor it to our needs (which basically means hard-code certain BYU-specific things) and remove some of the required parameters. Since this tool will be used by BYU employees only we had that option. We then morphed it a little more for our use cases. This isn’t something that you could use outside of BYU, sorry.
Installation
Install Python 3.x using your preferred method. See the installation options page for step by step instructions for installing in various environments.
See https://www.python.org/downloads/ for a windows installation method.
In linux you may be able to use apt, rpm or https://www.python.org/downloads/.
In Mac you can use homebrew, macports or https://www.python.org/downloads/.
Run pip3 install byu-awslogin
Usage
awslogin defaults to the default profile in your ~/.aws/config and ~/.aws/credentials files. *If you already have a default profile you want to save in your ~/.aws files make sure to do that before running awslogin.*
Once you’re logged in, you can execute commands using the AWS CLI or AWS SDK. Try running aws s3 ls.
Currently, awslogin tokens are only valid for 1 hour due to the assume_role_with_saml AWS API call has a max timeout of 1 hour.
To use it:
Run awslogin and it will prompt you for the AWS account and role to use.
Run awslogin --account <account name> --role <role name> to skip the prompting for account and name. You could specify just one of the arguments as well.
Run awslogin --profile <profile name> to specifiy an alternative profile
Run awslogin -- --help for full help message
Reporting bugs or requesting features
Enter an issue on the github repo.

Update the version in the VERSION file.
Commit the change and push. Handel-codepipeline will run the automated tests and if they pass it will build and upload a new version to pypi.
TODO
gracefully handle the error case when the duo push is rejected
Add support for profiles (@dsw88 is this already done?)
Authenticate once for 8 hours and rerun awslogin to relogin
Write tests - roles.py - assume_role.py
