[bug\_fix] Azure SDK throws 'AADSTS7000222: The provided client secret keys are expired' for Service Principal authentication

Generate a new client secret in the Azure Portal \(Microsoft Entra ID > App registrations > Certificates & secrets\) or via \`az ad app credential reset\`, immediately copy the secret value \(which is only shown once\), and update the environment variable \(AZURE\_CLIENT\_SECRET\) or Key Vault reference used by your application. The root cause is that Azure AD \(Entra ID\) client secrets have a mandatory expiration date \(default 1 year, max 2 years depending on tenant policy\), and the token endpoint rejects authentication requests using expired secrets with AADSTS7000222.

Journey Context:
Your production Python application running on a VM suddenly fails to start with msrestazure.exceptions.AuthenticationError containing 'AADSTS7000222'. The app uses Service Principal auth with client\_id, client\_secret, and tenant\_id from environment variables. You check the Azure Portal > Microsoft Entra ID > App registrations > \[YourApp\] > Certificates & secrets and see the secret listed with an 'Expires' date of yesterday. You recall creating this secret 2 years ago. You attempt to use the existing secret value again but the error persists because Azure AD has invalidated it. You click 'New client secret', add a description 'prod-secret-2024', set expiration to 24 months, and click Add. The portal displays the secret value only once. You copy it immediately, update the AZURE\_CLIENT\_SECRET in your VM's environment variables \(or your CI/CD secret store\), and restart the application. It authenticates successfully. To prevent future outages, you implement a secret rotation policy using Azure Key Vault with automated rotation or switch to Managed Identity for Azure resources which eliminates secrets entirely.
