Does Microsoft Entra (Entra ID / Azure AD) automatically notify app owners when client secrets are about to expire?

For Microsoft Entra app registrations, there is no documented out-of-the-box feature in the provided material that automatically emails application owners when a client secret is nearing expiration.

Supported built-in options shown in the material are:

1. Manual monitoring in the app registration
   • Go to Microsoft Entra admin center → App registrations → select the app → Certificates & secrets.
   • Check the Expires column for each client secret.
2. Microsoft Entra recommendations
   • Microsoft Entra includes the recommendation Renew expiring application credentials.
   • The recommendations overview shows this recommendation targets Application Administrator for email notifications.
   • The Microsoft.Identity.Web guidance also states that Microsoft Entra recommendations can be set up to receive alerts before credentials expire.
3. Rotation planning
   • Client secrets have a maximum lifetime and expire on the date specified during creation.
   • Microsoft recommends planning rotation to avoid outages.
   • For apps using Microsoft.Identity.Web, a zero-downtime pattern is to add a new secret first in the ClientCredentials array, deploy, validate, and then remove the old secret.
4. Monitoring and automation patterns
   • The security operations guidance recommends monitoring applications for long credential expiration times and using Microsoft Graph to find credential start and end dates.
   • It also points to prebuilt monitoring and alerting options such as Microsoft Sentinel, Azure Monitor, Defender for Cloud Apps, and a sample PowerShell script to find credential lifetime.
   • The certificates FAQ states that app registrations with expiring secrets and certificates can be exported through PowerShell scripts.

What can be answered directly for each question:

1. Automatic per-owner notifications for expiring client secrets
   • No documented per-owner automatic email or Teams notification feature for client secrets is shown.
   • The documented native capabilities are the Certificates & secrets expiry view and Microsoft Entra recommendations.
2. Tenant settings, preview features, or recommendation-based alerts
   • The recommendation Renew expiring application credentials exists and is listed as Preview.
   • The recommendations table indicates Application Administrator as the target role for email notifications.
   • No tenant setting is shown that sends notifications specifically to each application owner, and no Teams alert capability is documented in the provided material.
3. Microsoft-recommended monitoring patterns if native alerts are insufficient
   • Use Certificates & secrets to track expiration dates.
   • Use Microsoft Entra recommendations for alerting on expiring application credentials.
   • Use Microsoft Graph or the referenced PowerShell scripts to inventory credentials and expiration dates.
   • Use monitoring/alerting integrations called out in the security operations guidance: Microsoft Sentinel, Azure Monitor, Defender for Cloud Apps, and PowerShell-based reporting.
   • Rotate secrets before expiry; for Microsoft.Identity.Web apps, use the documented dual-secret approach for zero downtime.
4. Roadmap or upcoming features
   • No roadmap or upcoming feature for automatic client-secret expiry notifications is described in the provided material.
