RIO Education is a native Salesforce Student Information System (SIS, SMS).

It does not perform any callouts to external/3rd party services, hence, by default, RIO Education does not utilize any keys/certificates.

This also means that we do not store or manage any customer-related keys/certificates. 

If you are using any external/3rd party services or apps, the keys/certificates are managed within your own Salesforce instance.

One of the commonly used 3rd party apps that require a certificate is S-Docs (it is a template generation app); the certificate is only required if the app has to run as a specific user. 

If you are using any external/3rd party app, and you encounter any issues that are related to them (e.g. expired certificate), kindly refer to the relevant external/3rd party app.
