Microsoft Copilot Studio: Enforce safe sharing by detecting credential oversharing

This feature helps organizations reduce security risk by preventing agents and flows from being shared when they rely on unsafe identities, such as maker credentials. By detecting identity oversharing early and enforcing safe‑sharing policies at publish and share time, customers can avoid identity leakage, privilege escalation, and unintended access - while still allowing makers to build and iterate safely within approved guardrails.
