Hello, NetWorker does not support Two-Factor Authentication (2FA) or Multifactor Authentication (MFA) for Active Directory/LDAP Users.

https://www.dell.com/support/kbdoc/en-us/000218615/networker-two-factor-authentication-2fa-or-multifactor-authentication-mfa-for-ad-ldap-users

I am checking whether 2FA can be enable for networker admin accounts for security reasons.

we are still on version 19.8.0.1 Build.52

As of NetWorker version 19.8.0.1 Build.52, native support for 2FA (Two-Factor Authentication) is not available for admin accounts, especially if you're using Active Directory (AD) or LDAP-based authentication. 

Limitations in Version 19.8.0.1

• No built-in 2FA for AD/LDAP users.
• Local NetWorker accounts also lack 2FA support in this version.
• MFA support was introduced in NetWorker 19.12 and later, specifically for local accounts using Google Authenticator.
  
  Upgrade required.
• Upgrade to NetWorker 19.12 or newer to enable MFA for local users.
• For AD/LDAP users, Dell has filed an enhancement request (RFE NW-I-1764), but it's not yet implemented.
• Consider using external authentication gateways or VPN-based access controls to add a layer of security around NMC access.
