Report Users with NO Alternative Authentication Phone

Regular Contributor

Hi All

 

Is it possible to create a report showing users with / without an Alternative Authentication Phone Number?

 

Info greatly appreciated

Great article, however, nothing happens when the following command is run:

 

$Result | Where {$_.MFAStatus -ne "Disabled" -and $_.AlternativePhoneNumber -eq $null}

 

List all MFA enabled users without Alternative Authentication Phone Number

 

Any ideas?

Hi Kevin

 

I do hope you are well.

 

Anyway, I did manage to get the following script running 

List all MFA enabled users without Alternative Authentication Phone Number

 

However the output list Users, including myself that DO actually have a 2nd auth phone.

 

Any ideas?

Can you run the below command (after replacing your account's UPN) to check the "AlternativePhoneNumber" is configured or not.

 

$user = Get-MsolUser -UserPrincipalName "UserName@Domain.onmicrosoft.com"
$alternativePhoneNumber = $user.StrongAuthenticationUserDetails.AlternativePhoneNumber
if($alternativePhoneNumber -ne $null) { 
Write-Host "AlternativePhoneNumber:" $alternativePhoneNumber -ForegroundColor Green
} Else {
Write-Host "Alternative auth phone number not configured" -ForegroundColor Red
}

Note : This script extracting 2nd auth phone number from MFA Authentication User Details, not from user's Alternative Mobile Number :  $user.AlternateMobilePhones

Hi Kevin

 

Yes this works, it displays my alternative mob number.

 

Can this be done tenant wide?

Can you try the below script to list all users without alternative auth phone number.

 

$Result=@()
$users = Get-MsolUser -All
$users | ForEach-Object {
$user = $_
$alternativePhoneNumber = $user.StrongAuthenticationUserDetails.AlternativePhoneNumber
if($alternativePhoneNumber -eq $null) { 
$Result += New-Object PSObject -property @{ 
UserName = $user.DisplayName
UserPrincipalName = $user.UserPrincipalName
}
}
}
$Result | Select UserName,UserPrincipalName

Or you can try below script to list only MFA enabled users without alternative auth phone.

$Result=@()
$users = Get-MsolUser -All | Where {$_.StrongAuthenticationMethods -ne $null -or $_.StrongAuthenticationRequirements.State -ne $nul}
$users | ForEach-Object {
$user = $_
$alternativePhoneNumber = $user.StrongAuthenticationUserDetails.AlternativePhoneNumber
if($alternativePhoneNumber -eq $null) { 
$Result += New-Object PSObject -property @{ 
UserName = $user.DisplayName
UserPrincipalName = $user.UserPrincipalName
}
}
}
$Result | Select UserName,UserPrincipalName

2nd script looks good.

 

Your an absolute genius, thank you so much.
