@roundtables/awsmfa

awsmfa

The awsmfa command simplifies your process of securing a valid session from a user that has an MFA device.

It walks you through a series of questions and helps restart your shell that has a valid session. It also suggests a command to run directly in the future.

Prerequisites

You need nodejs to be installed first.

Installation

For npm users:

$ npm i -g @roundtables/awsmfa

For yarn users:

$ yarn global add @roundtables/awsmfa

If you would like to try without installing it first:

$ npx @roundtables/awsmfa

Usage

First time

Just run awsmfa without arguments and follow through the instructinos

After the first time

awsmfa will provide you with the commandline to directly setup your AWS environment without going through the interactive steps.

We recommend you add those awsmfa suggested commands as aliases on your system

Usage examples

$ awsmfa

To run without interactive prompt (useful for setting up aliases) (in this example, I use the aws sdk's myclient profile and my MFA device is linked to the account 999999999999 with a mfaCode 2983)

$ awsmfa --profile=myclient --mfaARN=arn:aws:iam::999999999999:mfa/myuser --mfaCode=2983

Interactive prompt only for mfaCode (useful for setting up aliases)

$ awsmfa --profile=myclient --mfaARN=arn:aws:iam::999999999999:mfa/myuser

To run a specific command rather than your shell (in this example aws2 s3 ls)

$ awsmfa --profile=myclient --mfaARN=arn:aws:iam::999999999999:mfa/myuser --mfaCode=2983 aws2 s3 ls

To run as a specific role

$ awsmfa --profile=myclient --mfaARN=arn:aws:iam::999999999999:mfa/myuser --mfaCode=2983 --role=arn:aws:iam::999999999999:role/OrganizationAccountAccessRole

To run as a specific role by specifying account and role instead of ARN

$ awsmfa --profile=myclient --mfaARN=arn:aws:iam::999999999999:mfa/myuser --mfaCode=2983 --account=999999999999 --role=OrganizationAccountAccessRole

To assume the role default created OrganizationAccountAccessRole role as an SSO method we omit the role and only specify the account

$ awsmfa --profile=myclient --mfaARN=arn:aws:iam::999999999999:mfa/myuser --mfaCode=2983 --account=999999999999
