Abstract

Starting NetBackup 10.3, users can configure multi-factor authentication (MFA) for themselves. Multi-factor authentication in NetBackup 10.3 implements recommendations from RFC-6238 “TOTP: Time-Based One-Time Password Algorithm”.

Description

NetBackup 10.3 implements RFC-6238 “TOTP: Time-Based One-Time Password Algorithm” to enable users to configure their multifactor authentication. Implementation being based on open standard (RFC-6238); one may use any TOTP application confirming to such RFC mentioned earlier. The process of acquiring such an application would differ from one platform (Android, iOS, Desktop) to another, thus we shall restrict our discussion to a couple of widely used, such as: 

  • Microsoft Authenticator 
  • Google Authenticator 
  • Okta Authenticator 

This document assumes users would have a working TOTP application installed on their devices which adheres to RFC stated above.
