Automating with PowerShell: Getting new Secure App Model tokens

Kelvin Tegelaar | 20 Jan, 2022 | 1 Mins Read

Since I’ve released CIPP I’ve been getting a load of questions about the Secure Application Model, one of the most common occurrences happens to be that users somehow don’t get their tokens setup completely, and need to retrieve these again.

Setting all the permissions and such can be a hassle so you don’t want to recreate the entire app. This script allows you to retrieve new tokens, you can use these tokens in CIPP or different locations.

When using CIPP, you only need to do this once as it takes over management of the tokens and refreshes them each week automatically.

$ApplicationId = 'ApplicationID'
$ApplicationSecret = 'Secret' | Convertto-SecureString -AsPlainText -Force
$TenantID = 'YourTenantID'
$credential = New-Object System.Management.Automation.PSCredential($ApplicationId, $ApplicationSecret)
$token = New-PartnerAccessToken -ApplicationId $ApplicationID -Scopes 'https://api.partnercenter.microsoft.com/user_impersonation' -ServicePrincipal -Credential $credential -Tenant $TenantID -UseAuthorizationCode
$Exchangetoken = New-PartnerAccessToken -ApplicationId 'a0c73c16-a7e3-4564-9a95-2bdf47383716' -Scopes 'https://outlook.office365.com/.default' -Tenant $TenantID -UseDeviceAuthentication
Write-Host "================ Secrets ================"
Write-Host "`$ApplicationId         = $($applicationID)"
Write-Host "`$ApplicationSecret     = $($ApplicationSecret)"
Write-Host "`$TenantID              = $($tenantid)"
write-host "`$RefreshToken          = $($token.refreshtoken)" -ForegroundColor Blue
write-host "`$ExchangeRefreshToken  = $($ExchangeToken.Refreshtoken)" -ForegroundColor Green
Write-Host "================ Secrets ================"
Write-Host "    SAVE THESE IN A SECURE LOCATION     "

As always, Happy PowerShelling 🙂

CyberDrain CTF returns! (and so do I!)

It’s been since september that I actually picked up a digital pen equivalent and wrote anything down. This was due to me being busy with life but also my side projects like CIPP. I’m trying to get back into the game of scripting and blogging about these scripts. There’s still so much to automate and so little time, right? ;)

Intro

This is a monitoring script requested via Reddit, One of the reddit r/msp users wondered how they can monitor Acronis a little bit easier. I jumped on this because it happened pretty much at the same time that I was asked to speak at the Acronis CyberSummit so it kinda made sense to script this so I have something to demonstrate at my session there.

Intro

Wow! It’s been a while since I’ve blogged. I’ve just been so swamped with CIPP that I’ve just let the blogging go entirely. It’s a shame because I think out of all my hobbies it’s one I enjoy the most. It’s always nice helping others achieve their scripting target. I even got a couple of LinkedIn questions asking if I was done with blogging but I’m not. Writing always gives me some more piece of mind so I’ll try to catch up again. I know I’ve said that before but this time I’ll follow through. I’m sitting down right now and scheduling the release of 5 blogs in one go. No more whining and no more waiting.
