New Feature: New Authentication method for OneDrive on MacOS

MC207944, Stay Informed, Published date: Mar 27, 2020


OneDrive on MacOS is incorporating new methods for authentication.

  • We’ll be gradually rolling this out to new OneDrive on MacOS customers in mid-April 2020.
  • The rollout will be completed in mid-May.

This message is associated with Microsoft 365 Roadmap ID 1663659235.How does this affect me?

If you have not enabled OneDrive for Business for your tenant or you do not use MacOS, this message does not apply to you.

After this feature rolls out, your MacOS users who install the OneDrive sync client will be able to configure single sign on using their Office credentials. This feature will also enable conditional access.

  • OneDrive for Mac will respect conditional access for policies such as forced multi-factor authentication, location-based IP range filtering, and device compliance as managed in Microsoft Endpoint Manager Admin Center.
  • Accounts that are signed into Office will be a selectable option in OneDrive when a user adds a new sync account; this allows a user to setup OneDrive without prompting for password and credentials. 

In addition, the OneDrive sync client will share credentials with the MacOS Office suite.

  • Accounts that are signed into OneDrive will be available as a sign-in option in Office applications.

What do I need to do to prepare for this change?

This feature is applicable only to new MacOS OneDrive for Business users. Existing users are not affected by this update. If you want existing Mac users in your tenant to migrate to single sign on, they will need to unlink and then reauthenticate the Sync client. You might consider updating your user training and documentation.
