If you are using AWS for anything, and security is on top of your mind, you may
have run into some friction using the AWS services programatically. May companies
require MFA to be set up just to access the AWS console. Some go even further by
adding the constraint of requiring a group, or all users, to use MFA for programatic
access to their account. If you have ever been put into this situation and tried
to use the AWS APIs you know how it can become a burden to now do the things you
are used to doing from simple CLI calls.
