Web Sign In for Skype for Business

Web Sign In is enabled by default on the VVX phones registered with Skype for Business server and is available for Skype for Business Online and On-Premise deployments.

Web Sign In enables users to securely log in to Skype for Business on your VVX phone from a computer, or a mobile web browser. It allows users with an easy way to authenticate with Skype for Business credentials without providing inputs from the phone. Authentication is performed by navigating to Web Sign In and generating a Pair code on Polycom VVX phone and proceed with on-screen instructions.

Note that the sign-in method generates a pairing code that expires within a few minutes after the Skype for Business server sends the code to the phone. Users must sign in before the pairing code expires.

The default maximum number of phones a user can sign in concurrently is eight. If a user is signed in to multiple phones and signs out from one phone, that user remains signed in to the other phones.

Web Sign In supports Multi-Factor Authentication (MFA) on polycom phones. If you are using MFA, you must use Web Sign In as the user sign-in method with Polycom phones. For more information on configuring Office 365, see Microsoft's Configure Azure Multi-Factor Authentication Settings.

When VVX phones are signed in and the software is downgraded, the phones will be in the signed-in state until the User Certificates are valid.

All Skype for Business features are supported with Web Sign In for Skype for Business Online and On-Premise deployments.

Note: Web Sign In for Skype for Business server supports only when the Hybrid Modern Authentication (HMA) environment is enabled. To use the capability of HMA with Skype for Business On-Premise AAD should be federated with Azure AD. For more information to configure HMA in your environment, refer to Hybrid Modern Authentication for Skype for Business.
