1Password Agent Root Certificate is “Not Trusted”
If you use Wi-Fi syncing to sync with your iPhone or iPod touch, you will find the 1Password Agent self-signed root certificate in your login keychain:
You will also see the message “This root certificate is not trusted.” There is no reason to be concerned about this. This certificate is created when the 1Password application generates a self-signed certificate to provide SSL encryption between the desktop and iPhone/iPod touch applications.
Keychain Access reports that the certificate is “not trusted” because the self-signed certificate was generated on your local machine and cannot be “trusted” until it is signed by a “trusted third party” like Thawte or Verisign. There is no need to go through the hassle of signing the automatically generated certificate to provide an encrypted HTTPS connection for the purpose of Wi-Fi syncing between your own devices.
