Set-AdfsAzureMfaTenant

  • Reference
Module:
ADFS

Enables an AD FS farm to use MFA.

Syntax

Set-AdfsAzureMfaTenant
   -TenantId <String>
   -ClientId <String>
   [-WhatIf]
   [-Confirm]
   [<CommonParameters>]

Description

The Set-AdfsAzureMfaTenant cmdlet enables an Active Directory Federation Services (AD FS) farm to use Azure Multi-Factor Authentication (MFA) after a certificate has been created and registered in the Microsoft Entra tenant.

Examples

Example 1: Enable Azure MFA

PS C:\> $certbase64 = New-AdfsAzureMfaTenantCertificate -TenantID <your tenant ID>
PS C:\> New-MsolServicePrincipalCredential -AppPrincipalId 981f26a1-7f43-403b-a875-f8b09b8cd720 -Type asymmetric -Usage verify -Value $certBase64
PS C:\> Set-AdfsAzureMfaTenant -TenantId <your tenant ID> -ClientId 981f26a1-7f43-403b-a875-f8b09b8cd720

This command creates a certificate for Azure MFA, registers it in the tenant, and enables Azure MFA on the AD FS farm.

Example 2: Determine which certificate Azure MFA is using

$CertInBase64 = New-AdfsAzureMfaTenantCertificate -TenantID <your tenant ID>
[Security.Cryptography.X509Certificates.X509Certificate2]([System.Convert]::FromBase64String($CertInBase64))

After AD FS has been configured for Azure MFA, this command determines which certificate Azure MFA is using and when it expires.
