4. Configure IP Restriction: Restricting access with IP Blocking
You can allow an IP Address in a certain range for SSO or you can deny it based on your requirements and you can also challenge the user to verify their authenticity. Adaptive authentication manages the user authentication based on different factors such as Device ID, Location, Time of Access, IP Address, and many more, thus improving the security and functionality of Single Sign-On.
You can configure Adaptive Authentication with IP Blocking in the following way:
- Go to Adaptive Authentication from the left navigation bar.
