Guided Access is a local equivalent to Single App Mode, which provides some additional features, e.g. select area of screen available. Additionally a local passcode is required.
This is a local passcode and cannot be controlled by MDM. Once set, without the passcode there is no way to locally exit Guided Access.
Despite MDM having no control over Guide Access, it is still possible to disable the Guided Access, without the passcode, through MDM. This can be achieved in a couple of ways:
- Associate a Single App Mode profile through MDM
- Set the device into Lost Mode
By providing a Single App Mode profile to the device, MDM will overrule Guided Access. On removal of the Single App Mode Association from MDM, the device will be back to normal
Setting Lost Mode should have the same impact. Once Lost Mode is de-activated, again the device will be back to normal
