Deploying with MFA
Jets supports the use of Multi Factor Authentication, MFA. Jets leverages the tongueroo/aws-mfa-secure gem to achieve this.
Example
Set up mfa_serial for the aws profile section that requires it. Example:
~/.aws/credentials:
[mfa]
aws_access_key_id = BKCAXZ6ODJLQ1EXAMPLE
aws_secret_access_key = ABCDl4hXikfOHTvNqFAnb2Ea62bUuu/eUEXAMPLE
mfa_serial = arn:aws:iam::112233445566:mfa/MFAUser
Now you’ll be able to deploy like usual. Example:
$ AWS_PROFILE=mfa jets deploy
Please provide your MFA code: 004578

The MFA prompt will only appear once. The session credentials are reused until the session expires per the tongueroo/aws-mfa-secure docs.
