Installing Root and Personal Certificates on iOS

On this page:

Important
*You CANNOT install certificates on the mobile device without creating a passcode for it. This feature cannot be changed as it is an iOS design configuration setup by Apple, not MIT. If you prefer to keep your phone unlocked, please do not attempt to install certificates on the device.

*It is HIGHLY RECOMMENDED that you set a passcode for your device before you proceed with certificate installation. Failure to do so may cause complications with installing the certificates.

*If you currently have a personal certificate on your iOS device and wish to renew your personal certificate you must first remove your old personal certificate. Please follow these instructions on how to Deleting Personal Certificates from an iOS device before continuing.
