 If your organization created terms of use, other options might be visible under grant controls. These options allow administrators to require acknowledgment of terms of use as a condition of accessing the resources that the policy protects. You can find more information about terms of use in [Microsoft Entra terms of use](terms-of-use.md).
 
+## Multiple grant controls
+
+When multiple grant controls are applied to a user, it's important to understand that Conditional Access policies follow a specific validation order by design. For example, if a user has two policies requiring multifactor authentication (MFA) and Terms of Use (ToU), Conditional Access first validates the user's MFA claim and then the ToU.
+
+- If a valid MFA claim isn't present in the token, you see an "interrupt" (pending MFA) and a failure for ToU in the logs, even if the ToU was already accepted in a previous sign-in.
+- Once multifactor authentication is completed, a second log entry appears, validating the ToU. If the user already accepted the ToU, you see success for both MFA and ToU. 
+- If a valid MFA claim is present in the token, a single log shows success for both MFA and ToU.
+
+If multiple policies are applied to a user requiring MFA, Device State, and ToU, the process is similar. The validation order is MFA, Device State, and then ToU.

 ### Custom controls (preview)
 
 Custom controls are a preview capability of Microsoft Entra ID. When you use custom controls, your users are redirected to a compatible service to satisfy authentication requirements that are separate from Microsoft Entra ID. For more information, check out the [Custom controls](controls.md) article.
