Mona 1.0 and Entra client secret expiration

[caseywatson]

We’ve heard from some Mona users that customers are encountering an error when trying to purchase a SaaS subscription, specifically about a Marketplace token resolution failure. This is usually caused by an expired Entra client secret. Here’s how to check if your client secret has expired.

Upgrade Reminder: Mona 2.0 eliminates the need for client secrets entirely. If you’re ready to upgrade, skip these steps and enjoy a simplified setup.

If you’re still using Mona 1.0, follow these steps to check and replace your client secret:

1. Open your Entra ID app registrations in the Azure portal.
2. Search for your Mona deployment (it shares the same name).
3. Select the app registration and go to the Client credentials link in the Essentials section.
4. In the Client secrets tab, verify the expiration date.

If the client secret has expired:

1. Create a new client secret and set the expiration for at least a year.
   • Note: Save the secret and expiration date for future use.
2. Search for your Mona web app (it will be named mona-web-).
3. Go to Settings > Environment variables.
4. Update the Identity:AppIdentity:AadClientSecret value with the new secret, then save. The web app will restart.
5. Check your Logic Apps and other Marketplace API integrations, and update all client secrets with the new value.

Reminder: Upgrading to Mona 2.0 allows you to skip all these steps since client secrets are no longer required.
