Microsoft Entra FIDO2

Phone Up Cloud Telephony Desktop App (Versions before 2.1.0)

Microsoft Entra does not support FIDO2 as an authentication method for the Phone Up Cloud Telephony Desktop App in versions prior to 2.1.0. 

Note: Phone Up Cloud Telephony Desktop App 2.1.0 includes a configuration option that enables FIDO2 authentication for Microsoft Entra.

Microsoft Entra Conditional Access (based on Device ID)

Phone Up Cloud Telephony Desktop App (all versions)

Softphone Pro (all versions)

Microsoft Entra Conditional Access based on Device ID is not supported on desktop clients using embedded browsers. These embedded browsers do not transmit a Device ID, unlike Microsoft Edge.

Device ID–based Conditional Access works as expected when users sign in the Web App via a standard Microsoft Edge browser.
