Howdy folks,

We’ve heard from you that interconnected supply and distribution chains, and vendor models are bringing B2B partners directly into your business, where secure and seamless collaboration is more important than ever. We also know how painful it can be for IT managers to keep track of guest user accounts, and for end users to remember multiple usernames and passwords. We are continually improving our Azure AD External Identities solution with more support for bring-your-own-identity (BYOI) options.

Today, we are announcing another enhancement to our BYOI story with the general availability of email-based one-time passcode (email OTP) feature for collaboration.

With email OTP, org members can collaborate with anyone in the world by simply sharing a link or sending an invitation via email. Invited users prove their identity by using a verification code sent to their email account. Once authenticated, each session providing access to the shared resource lasts 24 hours. On subsequent sign ins, users receive a new one-time code via email, which they must enter to prove continued ownership of the email account and continue receiving access.

Azure AD treats email OTP-based users like other B2B guests, making them subject to security policies set by your organization such as Conditional Access, Multi-Factor Authentication (MFA) and periodic access reviews.

Email OTP is also being rolled out worldwide in Microsoft Teams preview mode.

To get started with email OTP, check out the documentation here. As always, we invite you to share any questions or feedback about the feature through the Azure forum or @AzureAD on Twitter.
