AWS singlesignon medium security documentation change

Service: singlesignon · 2025-10-16 · Security-related medium

File: singlesignon/latest/userguide/howtosignin.md

Summary

Rewrote sign-in instructions to focus on end-user experience, added details about one-time passwords (OTP) and verification codes, removed administrative configuration steps, and restructured content flow.

Security assessment

Added documentation about one-time passwords (OTP) for first-time sign-in and verification code requirements. These changes explicitly describe security features like temporary credentials and multi-factor authentication (MFA) workflows. The removal of root user/IAM credential usage recommendations also aligns with security best practices.
