At Doğuş Technology Company, where I work, more than one tenant works on the Azure side. A code has been developed that checks the expiration time of the keys in the app registrations under this tenant, if it is less than 10 days, send an e-mail.

Azure App Registration Key Expiration Checker

This Python script automates the process of checking the expiration time of keys in application registrations in different tenants on Azure. If the expiration time is less than 10 days, it sends an email notification. We also give an excel to the application. Excel contains the tenant id and app id of the applications. The script automatically reads and checks this.
