aws-mfa-login 1.0.1rc1

Generates environment variables for MFA auth against AWS CLI. Python 3.3+.

# aws-mfa-auth
Command-line tool for MFA authentication against the AWS CLI. Only generates environment variables, no state or configuration (MFA serial can optionally be added to AWS config).

Will by default ask for MFA token, and grab MFA device serial from the default profile in `~/.aws/config`.

Profile, serial and token can also be passed on the command line.

You must have a valid authentication for AWS CLI already set up for the STS call to succeed.

Examples:

```
> aws-mfa-login --help
usage: aws-mfa-login [-h] [--token TOKEN] [--profile PROFILE | --serial SERIAL]
[--fish | --bash]

optional arguments:
-h, --help show this help message and exit
--token TOKEN MFA token to use for login
--profile PROFILE AWS Profile to read MFA Serial from
--serial SERIAL MFA device serial (e.g.
arn:aws:iam::00000000000:mfa/myiamuser)
--fish Override shell guessing, set to fish (use "set -e")
--bash Override shell guessing, set to bash (use "unset")

> aws-mfa-login
