ORCID has redesigned the Account settings page - available by clicking your name in your ORCID record. This page gives an overview of your settings, like the default visibility setting and which emails you like to receive and how often. The Account settings page also contains a link to create a QR-code for your ORCID iD. 

The information about your Trusted parties, like the organizations (publishers, databases etc) you have granted permission to read your ORCID iD or to update your ORCID record, moved to a separate page. There you can find the links to revoke the access.
