Hi @GaneshErike ,

Navigate to System Properties:
- Use the navigation filter on the left-hand side of your ServiceNow instance.
- Type sys_properties.list and press Enter. This will open a list view of all system properties.
Locate the Timeout Property:
- In the list view, search for the Name of the property: glide.ui.session_timeout.
- If the property already exists, click on it to open its record.
- If it does not exist (this can happen in older instances), click New to create it.
Set the New Timeout Value:
- In the Value field, enter the desired session timeout in minutes. For example, enter 60 for a 60-minute timeout.
- Recommendation: The recommended value is 30 to 60 minutes. Setting it for an excessively long time can increase memory utilization and poses a security risk. ServiceNow treats values over 1440 minutes (one day) as one day.
Save the Changes:
- Click Update to save the property record. The new session timeout will be applied immediately

Hi @GaneshErike ,

No, updating the session timeout value in ServiceNow does not cause any downtime for the instance. The change is dynamic and takes effect immediately for new sessions

Hi @G Ponsekar ,

In our instance, there is a property - glide.sso.acr.ui.session.timeout and value is 30.

What this property will do, please let me know.

Thanks.

Hi @GaneshErike

The system property glide.sso.acr.ui.session.timeout manages the session timeout for users authenticating via Single Sign-On (SSO)

This property is part of a more advanced security setup than the standard session timeout (glide.ui.session_timeout).

Hi @G Ponsekar ,

We are using SSO to login to instance.

In this, I need to change the value of this property as well right.

Please let me know.

Thanks.
