Web Sign In for Skype for Business Online

Web Sign in is enabled by default on phones registered with Skype for Business Online and is available only for Skype for Business Online deployments.

Web Sign In enables users to securely log in to Skype for Business from the phone, a computer, or mobile web browser. The default maximum number of phones users can sign in to 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.

Note that this 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.

If you are using Multi-Factor Authentication (MFA), you must use Web Sign In as the user sign in method with Polycom phones. Note that if you are using MFA and you enable the remember Multi-Factor Authentication option on Office 365, the phones automatically sign out after the number of days specified in Office 365. For more information on configuring Office 365, see Microsoft's Configure Azure Multi-Factor Authentication Settings.

Note: This feature is not supported on VVX 250, 350, and 450 business IP phones. VVX business IP phones support on-premises deployments only.
