Time Out
Implementation Effort: Low
This setting is configured within existing Intune App Protection Policies and does not require infrastructure changes or device enrollment.
User Impact: Low
This setting operates in the background and does not require users to take action beyond reauthenticating after inactivity, which is a standard security expectation.
Overview
The Time Out setting in Microsoft Intune App Protection Policies (APP) defines how long a user can remain inactive before being required to reauthenticate using a PIN or biometric method. This helps prevent unauthorized access to corporate data if a device is left unattended. Admins can configure the timeout duration to balance security and user convenience, typically ranging from a few minutes to several hours.
This setting supports the Zero Trust principle of "Assume Breach" by limiting the window of opportunity for unauthorized access in case a device is lost, stolen, or left unattended. Without a timeout policy, sensitive data in corporate apps could remain accessible indefinitely, increasing the risk of data leakage.
