If you have set up the Multi-factor Authentication for your AWS account in order to use AWS CLI with this account you'll need to use Authenticator app to generate temporary credentials. Our AWS MFA CLI does that for you and creates a new temporary account within ~/.aws/credentials file.

1. If you are using NVM run nvm install. Otherwise just use Node v12+
2. Run npm i

1. Copy .env.example file to .env
2. Fill out the .env file with credentials of your main AWS account. Here's a description of the variables:

• PROFILE_NAME - the name of the new temporary profile. For example, mfa
• MAIN_PROFILE_NAME - the name of your main AWS profile which you set up. More details on the initial AWS CLI configuration here
• ACCOUNT_NUMBER - your main AWS account ID. How to find your AWS ID
• ACCOUNT_NAME - your IAM User name. To find it use this instruction, but instead look for IAM User in a dropdown
• TOKEN_TTL - defines for how much seconds is the temporary account is valid for. Max value is 129600 seconds (36 hours)

3. Run npm start and input an MFA token from your authenticator app.
4. Press enter and wait for the app to finish.
5. Done. You can use your newly generated AWS profile within TOKEN_TTL time.
