+[access-multiple-envs]: #how-to-access-two-iics-orgsenvironments-at-the-same-time
+It is not possible to access multiple IICS Orgs/Environments in a single browser session as login information is cached during the session. The following methods can be used if you require access to multiple Orgs/Environments:
+1. **Use multiple browsers**: Login to one Org/Environment in one browser (eg. Google Chrome), and use another browser (eg. Firefox) to login to another Org/Environment.
+1. **Private/Incognito mode**: Login to one Org/Environment in your normal browser window, and use a private/incognito browser window to login to another Org/Environment.
