At present, there is no way to grant "full administrative access"  to a secondary user. The main "registered user" has complete account access to device settings, but a secondary (aka "invited user") cannot access the full account settings. For example, my spouse needs to be able to reset a camera.

The lack of full account access can be life threatening is some cases as one could imagine. Users on Arlo.com have been asking for this feature for over 3 years to no avail. Kindly consider joining this petition in the hope that Arlo remedies this problem.
