Backing up iCloud Keychain on macOS 10.14

iCloud Keychain makes it extremely difficult to export your password data to a machine readable format, such as a .csv file. The reasoning behind this, is that Apple tries to keep its users within a closed ecosystem and by preventing easy migration of password data, they are increasing the barrier to switch to new platforms. Although I foresee myself being a longtime Mac user, I am not happy with the inability to backup my password manager. Fortunately, I have found an AppleScript that allows me to export my iCloud Keychain to a .csv file.

iCloud Keychain Backup Guide

This guide is for people running macOS Mojave 10.14.

  1. Open Script Editor on your Mac. Copy and paste the script at the bottom of the page.
  2. Look for the line after -- Type password - update to yours, that starts with keystroke "password", and change "password" to your user login password.
  3. Open a blank TextEdit document, and change the mode to Format -> Make Plain Text if it already isn't.
  4. Open Keychain Access and click on the iCloud Keychain at the top left. Then click the Passwords category at the bottom left.
  5. Sort the Keychain entries by Kind, descending. Select all the Web form password's, right click the selection, and note how many items there are. Then select just the first Keychain entry.
  6. In the Script Editor change repeat 1 times to what you noted earlier, e.g. repeat 201 times. Save the AppleScript.
  7. Click the play button in the Script Editor and wait a few minutes. My backup took around 30 minutes.
  8. You're done! Save the text file.
