Sharepoint app only key renewal
Hi Guys
We have a SharePoint app only created in 2020 and we successfully renewed that 3 years back
This app integration used for time-critical application
we hear that Microsoft is going to discontinue SharePoint app-only authentication April 2026
somehow our app key needed to be renewed in coming May 2025
we have found this script to do the renewal, but can you guys confirm this app key renewal is still valid ?
Best Regards
Radika

1. Access the Azure Portal
Sign in to the Azure Portal
Navigate to Azure Active Directory > Application Registration > Select your application
2. Create a new password
In the “Certificates and Passwords” tab
Click “+ New Client Password”
Select the expiration date (12 months recommended)
Copy the generated password immediately (you cannot view it again after closing)
3. Update the application configuration
Replace the old password with the new one in all SharePoint solutions that use it
4. Certificate authentication update (recommended)
Generate new certificate
Create self-signed certificates using Windows built-in tools
Or issue an official certificate through an enterprise CA
Upload to Azure AD
Upload a new certificate in the “Certificates” section of the application enrollment.
Record the certificate fingerprint (Thumbprint)
5. Configure the application
Update the certificate fingerprint information in the code
Ensure the certificate private key is properly stored
6. Validate after update
Test the connection:
powershell
Connect-PnPOnline -Url “https://yoursite.sharepoint.com” -ClientId “Application ID” -ClientSecret “New Password”
Check API permissions: Verify that the app still has the necessary SharePoint API permissionsHi Yoyce
Thanks for the reply
This is a Sharepoint App-only registered app and was created sometime back, it is not Azure App only registered app
Those apps we can't see from the Admin portal
