AWS cognito medium security documentation change

Service: cognito · 2026-01-25 · Security-related medium

File: cognito/latest/developerguide/cognito-identity-provider_example_cognito-identity-provider_AdminInitiateAuth_section.md

Summary

Added SAP ABAP SDK code example for AdminInitiateAuth API with SECRET_HASH handling.

Security assessment

The example explicitly demonstrates secure handling of SECRET_HASH (used for client secret validation) and proper authentication flow implementation. This prevents man-in-the-middle attacks and strengthens client authentication security.
