Correcting an Unsynchronized FileVault Password

On macOS systems, the JumpCloud Menu Bar App delivers a convenient method for users to reset their own JumpCloud passwords independently. As noted here, "Once the password is successfully saved using this App, JumpCloud has already done the heavy lifting to update FileVault and Keychain accordingly."

There are, however, alternate password reset workflows which may result in an unsynchronized state, between the user's FileVault access at initial system startup, and the user's subsequent macOS access after system startup is complete.

In such cases, when a previous password grants FileVault access before the current JumpCloud password grants subsequent macOS system access, the discrepancy is resolved with the following actions, as long as the previous password and the current password are both still known.
  1. Boot the system holding down Command-R, to put the system into Recovery Mode.
  2. When presented with the macOS Utilities screen in Recovery Mode, access the Utilities pull-down menu at upper left in the macOS system menu bar, and select Terminal.
  3. In Terminal, type "resetpassword" — all one word with no quotation marks — and hit Enter.
  4. The Reset Password utility will launch, the utility will examine local volumes for a moment, and the utility will then present three options. Choose "My password doesn't work when logging in" and click Next.
  5. Choose your JumpCloud user and click Next.
  6. Enter the current FileVault password to unlock the volume.
  7. Enter the current JumpCloud password in both the New password and Verify password fields and click Next.
MacOS will then prompt for a normal reboot, and afterward, the FileVault and macOS passwords will be properly synchronized.
