AWS IAM documentation change

Service: IAM · 2025-07-18 · Documentation low

File: IAM/latest/UserGuide/reference_identifiers.md

Summary

Added documentation sections about unique ID prefixes and obtaining unique identifiers, promoted subsections to main sections

Security assessment

The changes add visibility to documentation about security-relevant identifiers like access key IDs (including temporary ASIA prefixes) and methods to retrieve them. While this improves security documentation clarity, there's no evidence of addressing a specific vulnerability.
