 **Note:** If you have an MFA device attached to your account, the STS service will generate session tokens that are *invalid* unless you provide an MFA code. To enable MFA for a profile, specify the `mfa_serial` in `~/.aws/config`. You can retrieve the MFA's serial (ARN) in the web console, or you can usually derive it pretty easily using the format `arn:aws:iam::[account-id]:mfa/[your-iam-username]`. If you have an account with an MFA associated, but you don't provide the IAM, you are unable to call IAM services, even if you have the correct permissions to do so. `mfa_serial` will not be inherited from the profile designated in `source_profile` - you must include a reference to `mfa_serial` in every profile you wish to use it with.
