Sharing my master passwords with family in case of emergency

Hi all,

In the event of something unexpectedly happening to me, how do I make sure my family has my master passwords, login methods, etc?

My family aren't too tech-savy so I'm looking for a simple yet secure method of sharing my password manager master password with them + 2FA app location + banking passwords (that aren't in my password manager) + instructions of how to log into everything.

So all that written as text but stored/shared how?

Many thanks.
