How can I retrieve a list of all my instances, aside from using the Access tokens (=the standard way)?

It's difficult to tell what is being asked here. This question is ambiguous, vague, incomplete, overly broad, or rhetorical and cannot be reasonably answered in its current form. For help clarifying this question so that it can be reopened, see the FAQ.
The only supported way to get a list of your instance is to use the DescribeInstances API command (using any of the SDKs or command line tools).
Usually this requires you to use your access keys. The exception to this is if you are executing the DescribeInstances API command on an EC2 instance. If so, you can use EC2 Roles to avoid using the access keys.
