    And yet if you click export it will gladly print out a plaintext csv with your whole life in passwords. Doesn't even attempt to zip it with password or something.

    Does the macoOS login keychain get backed up by Time Machine backups in a way that could restore the keychain if the original machine's Secure Enclave is lost or destroyed?

    This is pretty much how it's suppose to work...

      Maybe but this is unexpected if you need to restore from a backup..

        I've done Tahoe-to-Tahoe migration assistant moves between machines in recent months. No issues with login keychain migration.

          But that’s not backup restore? I’m thinking Time Machine restore on a new Mac when old one is no longer working. Or when the old one had to be wiped and restored.

        Don't backup keys, rotate them.

          I can't rotate my keys if I lose access to accounts because my computer died and my backup is useless.

      I'm more interested by the fact that it apparently didn't work this way before Tahoe.

        IIRC there are options for exportable and un-exportable private keys when you make one in the secure enclave. Going to guess Tahoe made them un-exportable by default.

    This is good.
