Authenticate AWS CLI with MFA device.

You need python 2.7 running on your machine. For convenience, you can create an alias in your .bashrc to the authentication script, to do that run the following inside this directory:

echo "alias awsmfa='python $PWD/awsmfa.py'" >> ~/.bashrc
source ~/.bashrc

Run awsmfa for the first time and follow the instructions toconfigure your AWS account(s). Later you can add new AWS accounts by running awsmfa --configure or awsmfa -c.

To authenticate, simply run awsmfa and follow the instructions. For non-interactive authentication, use awsmfa -a <account-name> <mfa-code> or just awsmfa <mfa-code> if you have only one AWS account configured.

• Support py3
• Support switching between already authenticated accounts
