Managing DigiCert Certificates with Mobile Device Manager Plus

DigiCert is a certificate authority (CA) that issues certificates to mobile devices for enhanced app and data security. Mobile Device Manager Plus integrates with DigiCert to allow IT admins to simplify the creation and distribution of user-specific certificates.

By integrating the DigiCert CA with Mobile Device Manager Plus, organizations can provide passwordless authentication on mobile devices thereby reducing password reset requests and password fatigue for users. IT admins can also automate the renewal of certificates to ensure the devices always have the updated certificates available on them.

This document covers the steps involved in creating the CA server and template which are required to manage DigiCert certificates using Mobile Device Manager
