How to change the Session timeout value

Issue

• How to modify Liferay's default session-timeout of any logged-in user?

Environment

• Liferay DXP 7.2

Resolution

• This value is set on the [Application_Server-HOME]/webapps/ROOT/WEB-INF/web.xml file. You can change it:
• Manually by adjusting the property below, replacing X for the timeout value in minutes.

  <session-timeout>X</session-timeout>

• Creating an Ext plugin to Modify the web.xml
• There is a portal property that can be added to the portal-ext.properties but it is always overridden by the value set in web.xml. This property will only take effect if there is no <session-timeout> property on the web.xml file.

   # Specify the number of minutes before a session expires. This value is
   # always overridden by the value set in web.xml.
   #
   # Env: LIFERAY_SESSION_PERIOD_TIMEOUT
   #
   session.timeout=15
