-By default, on-premises users are signed out of their sessions after 30 minutes of inactivity. Admin users can use the local CLI access to either turn this feature on or off, or to adjust the inactivity thresholds. For more information, see [Defender for IoT CLI users and access](references-work-with-defender-for-iot-cli-commands.md) and [CLI command reference from OT network sensors](cli-ot-sensor.md).

-> [!NOTE]
-> Any changes made to user session timeouts are reset to defaults when you [update the OT monitoring software](update-ot-software.md).

-**Prerequisites**: This procedure is available for the *admin*, *cyberx*, and *cyberx_host* users only.

-**To control sensor user session timeouts**:
-
-1. Sign in to your sensor via a terminal and run:
-
-    ```cli
-    sudo nano /var/cyberx/properties/authentication.properties
-    ```
-
-    The following output appears:
-
-    ```cli
-    infinity_session_expiration=true
-    session_expiration_default_seconds=0
-    session_expiration_admin_seconds=1800
-    session_expiration_security_analyst_seconds=1800
-    session_expiration_read_only_users_seconds=1800
-    certifcate_validation=false
-    crl_timeout_secounds=3
-    crl_retries=1

-
-    - **To turn off user session timeouts entirely**, change `infinity_session_expiration=true` to `infinity_session_expiration=false`. Change it back to turn it back on again.
-
-    - **To adjust an inactivity timeout period**, adjust one of the following values to the required time, in seconds:
-
-        - `session_expiration_default_seconds` for all users
-        - `session_expiration_admin_seconds` for *Admin* users only
-        - `session_expiration_security_analyst_seconds` for *Security Analyst* users only
-        - `session_expiration_read_only_users_seconds` for *Read Only* users only
