There are two fail over options:
- Okta will automatically fail over to the default sign-in page.
- You can use on-prem IWA DSSO as a backup.
Choosing to fail over to on-prem IWA DSSO, requires you to install and configure the on-prem IWA DSSO. If on-prem IWA DSSO is configured and enabled, it will automatically take over if Agentless DSSO stops working. For details, see Install and configure the Okta IWA Web agent for Desktop Single Sign-on.
