Leave it in escrow with a lawyer, along with a copy of your will. If you are super cautious, leave an encrypted copy (or half the passwords etc) with one lawyer/escrow, and have a separate lawyer/escrow hold the decryption key/other half of the passwords etc. Along with easy instructions on how to decrypt! End of the day, if I die at an old age, my heirs will also be old and possibly not into computers/tech. I prefer a simple approach that requires minimum skill/effort on their part aside from presenting the relevant death certificate/paperwork to the lawyer.
