How to Issue QR Codes for Sign-In to Microsoft 365 Using Entra Portal and Microsoft Graph PowerShell

2025-02-08

QR codes have become a popular method for secure sign-ins, and Microsoft 365 now supports this feature through the Entra portal and Microsoft Graph PowerShell. This article will guide you through the process of registering QR codes for sign-in, along with practical commands and codes to implement this feature.

Registering QR Codes via Entra Portal

Access the Entra Portal: Log in to the Entra portal using your administrator credentials.
Navigate to Authentication Methods: Go to the “Authentication Methods” section under the “Security” settings.
Enable QR Code Authentication: Locate the QR code authentication method and enable it for your organization.
Assign QR Codes to Users: Select the users you want to assign QR codes to and register the method for them.

Registering QR Codes via Microsoft Graph PowerShell

To automate the process, you can use Microsoft Graph PowerShell. Below are the steps and commands to register QR codes for users:

Install Microsoft Graph Module: If you haven’t already, install the Microsoft Graph PowerShell module.
```
Install-Module -Name Microsoft.Graph -Force -Scope AllUsers
```

Connect to Microsoft Graph: Authenticate and connect to Microsoft Graph.

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

Register QR Code Authentication for a User: Use the following command to register the QR code authentication method for a specific user.
```
$userId = "user-id-here"
$params = @{
"methodType" = "qrCode"
}
New-MgUserAuthenticationMethod -UserId $userId -BodyParameter $params
```
Verify the Registration: You can verify the registration by listing the authentication methods for the user.
```
Get-MgUserAuthenticationMethod -UserId $userId
```

Limitations and Future Expectations

Currently, there are some limitations:

Conditional Access: You cannot enforce QR code sign-in through Conditional Access yet.
My Security Info Page: QR codes cannot be managed from the My Security Info page.
Office.com Sign-In: Signing in using QR codes from office.com is not supported.

However, these features are expected to be rolled out soon.

What Undercode Say

QR code authentication is a significant step forward in enhancing security and user convenience. By leveraging the Entra portal and Microsoft Graph PowerShell, administrators can efficiently manage and deploy this authentication method. Here are some additional Linux and IT-related commands that can complement your cybersecurity practices:

Generate QR Codes in Linux: Use `qrencode` to generate QR codes in a Linux environment.
```
sudo apt-get install qrencode
qrencode -o qrcode.png "https://your-link-here"
```

Secure SSH with QR Codes: Enhance SSH security by using QR codes for key exchange.

ssh-keygen -t rsa -b 4096 -C "[email protected]"
qrencode -t ANSIUTF8 < ~/.ssh/id_rsa.pub

Network Security with QR Codes: Use QR codes to share Wi-Fi credentials securely.
```
echo "WIFI:S:YourSSID;T:WPA;P:YourPassword;;" | qrencode -o wifi.png
```
Automate QR Code Scanning: Use `zbar-tools` to scan QR codes from the command line.
```
sudo apt-get install zbar-tools
zbarcam /dev/video0
```

Integrate QR Codes with APIs: Automate QR code generation and scanning using Python scripts.

import qrcode
qr = qrcode.QRCode(version=1, box_size=10, border=5)
qr.add_data("https://your-link-here")
qr.make(fit=True)
img = qr.make_image(fill='black', back_color='white')
img.save('qrcode.png')

Enhance Security with Two-Factor Authentication (2FA): Implement 2FA using QR codes for additional security.
```
google-authenticator
```
Monitor System Logs: Use `journalctl` to monitor system logs for security breaches.
```
journalctl -xe
```
Secure File Transfers: Use `scp` for secure file transfers over SSH.
```
scp file.txt user@remote:/path/to/destination
```
Encrypt Files with GPG: Encrypt sensitive files using GPG.
```
gpg -c file.txt
```
Check for Open Ports: Use `nmap` to scan for open ports on your network.
```
nmap -sV -p 1-65535 192.168.1.1
```

By integrating these commands and practices, you can significantly enhance your cybersecurity posture. QR codes, when used correctly, can provide a seamless and secure authentication method, reducing the risk of phishing and other cyber threats.
