Troubleshooting combined security information registration

  • Άρθρο

The information in this article is meant to guide admins who are troubleshooting issues reported by users of the combined registration experience.

Audit logs

The events logged for combined registration are in the Authentication Methods service in the Microsoft Entra audit logs.

Microsoft Entra audit logs interface showing registration events

The following table lists all audit events generated by combined registration:

Troubleshooting interrupt mode

Symptom Troubleshooting steps
I'm not seeing the methods I expected to see. 1. Check if the user has a Microsoft Entra admin role. If yes, view the SSPR admin policy differences.
2. Determine whether the user is being interrupted because of multifactor authentication registration enforcement or SSPR registration enforcement. See the flowchart under "Combined registration modes" to determine which methods should be shown.
3. Determine how recently the multifactor authentication or SSPR policy was changed. If the change was recent, it might take some time for the updated policy to propagate.

Troubleshooting manage mode

Symptom Troubleshooting steps
I don't have the option to add a particular method. 1. Determine whether the method is enabled for multifactor authentication or for SSPR.
2. If the method is enabled, save the policies again and wait 1-2 hours before testing again.
3. If the method is enabled, ensure that the user hasn't already set up the maximum number of that method that they're allowed to set up.

How to roll back users

If you, as an admin, want to reset a user's multifactor authentication settings, you can use the PowerShell script provided in the next section. The script will clear the StrongAuthenticationMethods property for a user's mobile app and/or phone number. If you run this script for your users, they'll need to re-register for multifactor authentication if they need it. We recommend testing rollback with one or two users before rolling back all affected users.

The steps that follow will help you roll back a user or group of users.

Prerequisites

Note

Azure AD and MSOnline PowerShell modules are deprecated as of March 30, 2024. To learn more, read the deprecation update. After this date, support for these modules are limited to migration assistance to Microsoft Graph PowerShell SDK and security fixes. The deprecated modules will continue to function through March, 30 2025.

We recommend migrating to Microsoft Graph PowerShell to interact with Microsoft Entra ID (formerly Azure AD). For common migration questions, refer to the Migration FAQ. Note: Versions 1.0.x of MSOnline may experience disruption after June 30, 2024.

  1. Install the appropriate Azure AD PowerShell modules. In a PowerShell window, run these commands to install the modules:

    Install-Module -Name MSOnline
Import-Module MSOnline

  2. Save the list of affected user object IDs to your computer as a text file with one ID per line. Make note of the location of the file.

  3. Save the following script to your computer and make note of the location of the script:

    <# 
//********************************************************
//*                                                      *
//*   Copyright (C) Microsoft. All rights reserved.      *
//*                                                      *
//********************************************************
#>

param($path)

# Define Remediation Fn
function RemediateUser {

    param  
    (
        $ObjectId
    )

    $user = Get-MsolUser -ObjectId $ObjectId

    Write-Host "Checking if user is eligible for rollback: UPN: "  $user.UserPrincipalName  " ObjectId: "  $user.ObjectId -ForegroundColor Yellow

    $hasMfaRelyingParty = $false
    foreach($p in $user.StrongAuthenticationRequirements)
    {
        if ($p.RelyingParty -eq "*")
        {
            $hasMfaRelyingParty = $true
            Write-Host "User was enabled for per-user MFA." -ForegroundColor Yellow
        }
    }

    if ($user.StrongAuthenticationMethods.Count -gt 0 -and -not $hasMfaRelyingParty)
    {
        Write-Host $user.UserPrincipalName " is eligible for rollback" -ForegroundColor Yellow
        Write-Host "Rolling back user ..." -ForegroundColor Yellow
        Reset-MsolStrongAuthenticationMethodByUpn -UserPrincipalName $user.UserPrincipalName
        Write-Host "Successfully rolled back user " $user.UserPrincipalName -ForegroundColor Green
    }
    else
    {
        Write-Host $user.UserPrincipalName " is not eligible for rollback. No action required."
    }

    Write-Host ""
    Start-Sleep -Milliseconds 750
}

# Connect
Import-Module MSOnline
Connect-MsolService

foreach($line in Get-Content $path)
{
    RemediateUser -ObjectId $line
}

Rollback

In a PowerShell window, run the following command, providing the script and user file locations. Provide at least Privileged Authentication Administrator credentials when prompted. The script will output the outcome of each user update operation.

<script location> -path <user file location>
