Up to three passphrases ("slots") can open the backup key, so that one person leaving or dying
|
|
does not lock you out. Example: one passphrase in the safe, one with the CTO, one with the head
|
|
of IT. Each holder keeps a copy of the same recovery kit and only knows their own passphrase.
|
|
After every change: occ backup:key:kit and occ backup:key:confirm.
