Thanks, this actually helped give me a good idea about how I would like to do this now:

1. Generate the password for the owner account, store that in "standard" secrets storage where admins can access it. 2. Also require TOTP MFA for the owner account. Take the seed for the TOTP, and split that into N shares (where N is equal to the number of admins you want to share it out to) requiring K threshold (where K is the minimum number of admins that must come together), and give that out to your admins.
