It depends on what you need. For some things, it may be interesting
to gain access before the estate has been settled. In other cases,
you want to precisely avoid that.
Secret sharing does not work socially in the long term because you
eventually need to handle revocation, and that could become quite
stressful. It also exposes the sharing parties to government pressure
even before death.
Maybe sharing passwords is not the answer anyway because it allows
perfect impersonation. Other forms of delegation might be more
appropriate because they can be audited in a more straightforward way.
