PhoneFactor

PhoneFactor is a multi-factor authentication system which utilizes phone calls to verify identity.[1][2] With multiple out-of-band methods (phone call, text message, and push) and an OAUTH passcode option, PhoneFactor provides flexibility for users and a single multi-factor platform for IT to manage.[3]

On October 4, 2012, it was announced that Microsoft had acquired PhoneFactor.[4] The PhoneFactor service is now available as Azure Multi-Factor Authentication. In addition to securing on-premises applications and identities, the service now also works with cloud applications like Office 365 that use Windows Azure Active Directory.

Background

Founded in 2001,[5] PhoneFactor helps organizations address user demand for a simple sign-in process while also meeting security and compliance standards. By leveraging a device every user already has – a phone – PhoneFactor enables scalable, user-friendly, secure[6] multi-factor authentication.
