Microsoft will soon fast-track multi-factor authentication adoption for its Microsoft 365 cloud productivity platform by adding MFA capabilities to the Outlook email client.
The company says in a new Microsoft 365 roadmap entry that users will be able to complete MFA requests for Microsoft 365 apps directly in the Outlook app via a new feature dubbed Authenticator Lite.
"Authenticator Lite is a feature that allows your users to complete multi-factor authentication for their work or school account using the Outlook app on their iOS or Android device," Microsoft explains.
At the moment, Microsoft 365 MFA requests can be completed using verification codes obtained via an authentication app, a security key, a phone call, or text messaging.
Microsoft's decision could boost MFA adoption among Microsoft 365 users, as Outlook has a much larger user base than Microsoft's Authenticator app.
The Outlook app has more than 500 million downloads on Android and 5.5 million reviews on iOS, while the Authenticator app has 50 million downloads on Android and 233,100 reviews on iOS. Once rolled out, the new Authenticator Lite feature will allow hundreds of millions more Microsoft 365 customers to enable and use MFA to secure their accounts.
