Application Management certificates frequently asked questions
This page answers frequently asked questions about managing the certificates for apps using Azure Active Directory (Azure AD) as an Identity Provider (IdP).
Is there a way to generate a list of expiring SAML signing certificates?
You can export all app registrations with expiring secrets, certificates and their owners for the specified apps from your directory in a CSV file through PowerShell scripts.
Where can I find the information about soon to expire certificates renewal steps?
You can find the steps here.
How can I customize the expiration date for the certificates issued by Azure AD?
By default, Azure AD configures a certificate to expire after three years when it is created automatically during SAML single sign-on configuration. Because you can't change the date of a certificate after you save it, you need to create a new certificate. For steps on how to do so, please refer Customize the expiration date for your federation certificate and roll it over to a new certificate.
How can I automate the certificates expiration notifications?
Azure AD will send an email notification 60, 30, and 7 days before the SAML certificate expires. You may add more than one email address to receive notifications.
You can add up to 5 email addresses to the Notification list (including the email address of the admin who added the application). If you need more people to be notified, use the distribution list emails.
To specify the emails you want the notifications to be sent to, see Add email notification addresses for certificate expiration.
There is no option to edit or customize these email notifications received from
email@example.com. However, you can export app registrations with expiring secrets and certificates through PowerShell scripts.
Who can update the certificates?
The owner of the application or Global Administrator or Application Administrator can update the certificates through Azure portal UI, PowerShell or Microsoft Graph.
