Read this article before doing anything 🙂

Awesome!

First of all, we need to delete the old registration on SharePoint by running this following script: The clientId here should matched with the clientid in your AppManifest file

import-module MSOnline

$spURL = ‘https://devdevdev.sharepoint.com/sites/dev’

$adminUsername = ‘admin@devdevdev.onmicrosoft.com’

$password = ‘yourpassword’

$clientId = ‘f4243af8-dcb4-4e0d-be5a-4f37cca04ca8’

$securestring = ConvertTo-SecureString $password -AsPlainText -Force

$msolcred = new-object -typename System.Management.Automation.PSCredential -argumentlist $adminUsername, $securestring

connect-msolservice -credential $msolcred

$keys = Get-MsolServicePrincipalCredential -AppPrincipalId $clientId -ReturnKeyValues $false | Where-Object { ($_.Type -ne “Other”) -and ($_.Type -ne “Asymmetric”) }

foreach ($key in $keys)

{

$keyId = $key.KeyId.ToString()

Write-Host “Deleting key ” $keyId

Remove-MsolServicePrincipalCredential -KeyIds @($keyId) -AppPrincipalId $clientId

}

$servicePrincipal = Get-MsolServicePrincipal -ServicePrincipalName $clientId

Remove-MsolServicePrincipal -ObjectId $servicePrincipal.ObjectId

#Remove-MsolServicePrincipalCredential -KeyIds @(“KeyId1″,” KeyId2″,” KeyId3″) -AppPrincipalId $clientId

$bytes = New-Object Byte[] 32

$rand = [System.Security.Cryptography.RandomNumberGenerator]::Create()

$rand.GetBytes($bytes)

$rand.Dispose()

$newClientSecret = [System.Convert]::ToBase64String($bytes)

$dtStart = [System.DateTime]::Now

$dtEnd = $dtStart.AddYears(3).AddDays(-1)

New-MsolServicePrincipalCredential -AppPrincipalId $clientId -Type Symmetric -Usage Sign -Value $newClientSecret -StartDate $dtStart -EndDate $dtEnd

New-MsolServicePrincipalCredential -AppPrincipalId $clientId -Type Symmetric -Usage Verify -Value $newClientSecret -StartDate $dtStart -EndDate $dtEnd

New-MsolServicePrincipalCredential -AppPrincipalId $clientId -Type Password -Usage Verify -Value $newClientSecret -StartDate $dtStart -EndDate $dtEnd

$newClientSecret
Now, I have the new client secrect look like this: QDUgCbuyXLDwVFsWlrXMmrpYkvVP+VsUSOPp3vsXbDE=

It’s time to go to all of your backend web.config and update their ClientSecret

Now, go to your tenant and register it with new ClientSecrect:

Now, everything should work like before it’s expired!!!!
