IOS – How to remove a certificate from Certificate Trust Settings if the profile doesn’t exist

certificateiosSecurity

If I go to Settings > General > About > Certificate Trust Settings… I see several profiles installed under the "ENABLE FULL TRUST FOR ROOT CERTIFICATES" heading.

There is a way to toggle them off, but not disable them.

According to this website, it says that you can remove these certificates by navigating to Settings > General > Profiles. When I navigate there, I don't see any corresponding Profiles that are installed. They seem to have been deleted a while ago, yet the Certificates remain under Certificate Trust Settings.

Another site recommends to re-install the profile temporarily and then remove it. However, the profile is long gone and I don't know where to get it from.

How do I remove these certificates that don't have corresponding profiles on my phone?

I'm on iOS 13.3. I tested this using non-orphaned certificates in hopes of isolating the issue to see what is the minimum option you can use to remove these certificates.

Works:

  • Assuming you have the profile (i.e. non-orphaned): Settings > Profile > (Profile) > Remove
  • Nuclear option (deleting everything on your phone): Settings > General > Reset > Erase all content and settings

Doesn't work:

  • Settings > General > Reset > Reset network settings
  • Settings > General > Reset > Reset all settings
