To use MDM, you work with a Salesforce administrator and an MDM provider. The Salesforce administrator configures your connected app to suit your use case. The MDM provider is a trusted third party who distributes your mobile app settings to your customers’ devices. For example, you can use MDM to configure custom login URLs for your app. You can also use MDM for certificate-based authentication. In this case, you upload certificates to the MDM provider.
MDM enablement does not require changes to your Mobile SDK app code.
