To add conditional access through PowerShell, you can use the Azure AD PowerShell module (learn how to install), which allows you to manage Azure AD using cmdlets in a PowerShell environment.
Below is an example of how to create a conditional access policy that requires multi-factor authentication (MFA) for all cloud apps:
- First, you’ll need to connect to Azure AD using the Connect-AzureAD cmdlet:
Connect-AzureAD- Once connected, you can use the New-AzureADPolicy cmdlet to create a new conditional access policy:
$policy = New-AzureADPolicy -Definition @('{"RequireMFA":true}') -DisplayName "Require MFA for all cloud apps" -IsOrganizationDefault $true -Type "ConditionalAccess"
- Next, you can use the New-AzureADPolicyRule cmdlet to create a rule for the policy, which specifies the conditions that must be met for the policy to be enforced:
$rule = New-AzureADPolicyRule -PolicyId $policy.Id -Order 1 -Effect Allow -Conditions @('{"ClientApp":"All","Identity":"All"}')
- To apply the policy to all users, you can use the New-AzureADPolicyRoleSetting cmdlet to create a role setting that assigns the policy to the “Global” role:
New-AzureADPolicyRoleSetting -Id $policy.Id -RoleTemplateId "Global"
- Finally, you can use the Add-AzureADPolicyRule cmdlet to add the rule to the policy:
Add-AzureADPolicyRule -Id $policy.Id -RuleId $rule.Id
This will create a new conditional access policy that requires multi-factor authentication for all cloud apps and applies the policy to all users.
