Sign In Methods

You can configure users to sign in or out of the phone using one of the following methods:
  • User ID - Enable users to sign in with their user credentials on the Sign In screen. You cannot configure login credentials using the Web Configuration Utility.
  • PIN Authentication - Use this to sign in on the phone or from the Web Configuration Utility. As of UC Software 5.1.1, this sign in method is available on the SoundStructure VoIP Interface. This option is available in on-premises Skype for Business deployments when you configure DHCP Option 43 and is not available for online deployments.
  • Web Sign In for Skype for Business - This method enables secure sign-in from a browser on your computer or mobile device. The phone generates a unique pairing code used to sign in on a secure Office 365 website.
  • Single Sign-On Solutions (SSO) - Allows you to use the same login credentials across multiple cloud-based applications such as Microsoft Exchange and Skype for Business.

When you change the active directory password, the phone de-registers from the Skype for Business server with a registration expiry value.

The maximum length of the user name or sign in address (Name + Domain) is limited to 45 characters.

While signing in to the phone, the phone displays sign-in progress messages such as Discovering Skype for Business Server or Authentication in progress.
