PIN Authentication

You can enable users to sign in to Skype for Business using PIN authentication.

To use PIN authentication, you must enable the Web Configuration Utility, which is disabled by default. After you enable the Web Configuration Utility, you can enable or disable PIN authentication using reg.1.auth.usePinCredentials .

If you configure DHCP Option 43 in on-premises Skype for Business deployments, the phone displays only the PIN Authentication menu to users. The PIN Auth menu does not display and is not available for Skype for Business Online.
