Passbox

Passbox is a secure way to store all your passwords and access to sites in the event something happens to you, it would automatically send these information over to trusted users.

Its like a deadman switch where when something happens to you, the trusted user is able to request for the access provided and if it exceeded the wait period for you to deny access, the relevant information would then be provided to the trusted user.

There are Freemium and Paid plans for this service and its something which may be great for your loved ones to be able to gain access to important passwords if something suddenly happens to you.
