Step 2. Select Authentication Method

At this step of the wizard, choose whether you want to use modern or basic authentication.

Modern Authentication

To use modern authentication, do the following:

1. From the Specify the authentication method drop-down list, select Modern authentication.

This will allow Veeam Backup for Microsoft Office 365 to use an Azure AD application for a restore. Such an application is used to restore the specified object back to Office 365 organizations with enabled multi-factor authentication (MFA) and enabled or disabled security defaults.

For more information, see Microsoft Office 365 Organizations.

2. In the Application ID field, enter an identification number of the Azure AD application that you want to use for a restore.

By default, Veeam Explorer for Microsoft OneDrive for Business populates this field with the identification number of the application that was used during a backup session. If you want to use another application, make sure to grant this application required permissions. For more information, see Permissions for Modern App-Only Authentication.

Basic Authentication

To use basic authentication, do the following:

1. From the Specify the authentication method drop-down list, select Basic authentication.
2. Enter credentials to connect to the SharePoint organization.

On-Premises Organizations

To authenticate on an on-premises Microsoft SharePoint server, provide a user name and password.
