Bulk Provisioning QR Code + PIN Authentication in Microsoft Entra

By /

Listen to this Post

Microsoft recently introduced the QR code + PIN authentication method, currently in preview. While bulk provisioning isn’t natively supported, you can achieve this using PowerShell. Below is a script to bulk provision QR code authentication for all members of a group:


<h1>Import required modules</h1>

Import-Module Microsoft.Graph.Identity.SignIns

<h1>Connect to Microsoft Graph</h1>

Connect-MgGraph -Scopes "User.ReadWrite.All", "Group.ReadWrite.All"

<h1>Define the group ID</h1>

$groupId = "YOUR_GROUP_ID"

<h1>Get all members of the group</h1>

$groupMembers = Get-MgGroupMember -GroupId $groupId

<h1>Loop through each member and provision QR code authentication</h1>

foreach ($member in $groupMembers) {
$userId = $member.Id
$qrCodeAuth = @{
"methodType" = "qrCode"
"pin" = "123456" # Replace with a secure PIN generation logic
}
New-MgUserAuthenticationMethod -UserId $userId -BodyParameter $qrCodeAuth
}

<h1>Disconnect from Microsoft Graph</h1>

Disconnect-MgGraph

What Undercode Say

The of QR code + PIN authentication in Microsoft Entra is a significant step towards enhancing security and user convenience. However, the lack of native bulk provisioning can be a hurdle for organizations managing large user bases. By leveraging PowerShell, we can automate the provisioning process, ensuring that all group members are equipped with this new authentication method.

In the realm of cybersecurity, automation is key. The provided script demonstrates how to use Microsoft Graph API to interact with Microsoft Entra and automate the provisioning process. This approach not only saves time but also reduces the risk of human error.

For those working in IT and cybersecurity, mastering PowerShell is essential. Here are some additional commands that can be useful in various scenarios:

  • Check User Authentication Methods: 
    Get-MgUserAuthenticationMethod -UserId "USER_ID"

  • List All Groups in a Tenant:

    Get-MgGroup

  • Export Group Members to CSV:

    $groupMembers = Get-MgGroupMember -GroupId "GROUP_ID"
$groupMembers | Export-Csv -Path "group_members.csv" -NoTypeInformation

  • Remove a User from a Group:

    Remove-MgGroupMemberByRef -GroupId "GROUP_ID" -DirectoryObjectId "USER_ID"

  • Create a New Group:

    New-MgGroup -DisplayName "New Group" -MailEnabled $false -SecurityEnabled $true -MailNickname "newgroup"

In Linux environments, similar automation can be achieved using bash scripting and tools like `curl` and jq. For example, to list all users in a Linux system:

cut -d: -f1 /etc/passwd

Or to check the status of a service:

systemctl status SERVICE_NAME

For Windows, commands like `net user` and `net group` can be used to manage users and groups from the command line:

[cmd]
net user USERNAME
net group GROUPNAME
[/cmd]

In conclusion, the integration of QR code + PIN authentication in Microsoft Entra is a promising development. By combining this with automation tools like PowerShell, organizations can streamline their security processes, ensuring a robust and user-friendly authentication system. As always, staying updated with the latest security trends and continuously improving your scripting skills will keep you ahead in the ever-evolving field of IT and cybersecurity.
