Configuring or disabling multifactor authentication on a primary server instance
For NetBackup primary server application instances, you can configure or disable multifactor authentication through the NetBackup web UI the same way that you would for any other primary server. Once you configure multifactor authentication, it is required for both the NetBackup web UI and for SSH access to the instance.
See the NetBackup Web UI Administrator's Guide for the steps to configure or disable multifactor authentication on a primary server instance.
