The IAM username and password can only be used with the Amazon management console and their forums
My best solution so far is using a database where I mirror the iam user name and aws secret access key. With secret key encrypted ofc. But this still has the following drawbacks
- The secret aws key is stored in the database (even if it is not in clear text, it still is there)
- The clients would have the access keys of a user with the rights to list iam users and read access to the database.
So, there is no workaround for this i guess
