You can also print out your passwords and keep them with you end of life documents, depending on how often you change passwords if at all.

Or use a password manager, keep everything there and print out the „emergency kit“ that 1Password and probably others have.

Depends on the technical proficiency of whomever is going to inherit your accounts. I am familiar with folks where asking them to navigate a password manager would be not without challenges.

Indeed, it’s an interesting topic and always makes me a bit uneasy to think about it. Especially as a technical person where there’s credentials, keys, wallets all over the place.

I wish more companies would think about that and solve this in some way. 1Password could for example print out some instructions and have a support number to call listed directly there for someone who finds this document.

I have relatively technically incompetent family members, but my will instructs them to talk to any of 3 different technically competent friends that I trust (ideally more than 1 of them, all together in person with my estate providing funds for it) to guide them through shit like crypto private keys, password managers and encrypted archives that I could never imagine my very normal sister or mother dealing with. I check in with my friends every year to make sure that they're OK with the arrangement still, and the reason it's 3 is in case I'm involved in some kind of accident with 1 or more of them.

If by some freak accident all 4 of us die at once (at a bachelor party or something), I trust my heirs' competency to find someone who can guide them through it. I specify more than 1 because while I trust all the technical advisers, shit like gambling addiction can happen that I don't know about.

In return, I'm written in to help with similar circumstances for them.

The hard part is setting this up, but now it's just an annual email.

In a while, there will be three of you who have to come up with a replacement for the fourth... Or, your three friends for you.

Sorry, a bit morbid, I know. But something you‘ll have to think about nonetheless.

If you were worried about someone getting the password from your will before your death, you could use Shamir's secret sharing algorithm to spread a password among friends and relatives with instructions to not use it until after your death, so that some number of them have to agree to unlock it together.
