Step 2. Select Authentication Method

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

• Modern authentication
• 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 data restore. Such an application is used to restore the specified team back to Office 365 organizations with enabled multi-factor authentication (MFA) and enabled or disabled security defaults.

For more information, see the Microsoft Office 365 Organizations section of the Veeam Backup for Microsoft Office 365 User Guide.

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

By default, Veeam Explorer for Microsoft Teams 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, as described in the Azure AD Application Permissions section of the Veeam Backup for Microsoft Office 365 User Guide.

Basic Authentication

To use basic authentication, do the following:

1. From the Specify the authentication method drop-down list, select Basic authentication.
2. In the Username and Password fields, enter credentials to connect to the Microsoft Office 365 organization.
