Lists of available trusted root certificates in iOS

The iOS Trust Store contains trusted root certificates that are preinstalled with iOS.

About trust and certificates

Each iOS Trust Store listed below contains three categories of certificates:

  • Trusted certificates establish a chain of trust that verifies other certificates signed by the trusted roots—for example, to establish a secure connection to a web server. When IT administrators create Configuration Profiles for iOS, these trusted root certificates don't need to be included.
  • Always Ask certificates are untrusted but not blocked. When one of these certificates is used, you'll be prompted to choose whether or not to trust it.
  • Blocked certificates are believed to be compromised and will never be trusted.
