I'd say a regular will, sealed at a notary is just okay.
If you are really paranoid, why not write a service that works like a dead mans switch and when you don't trigger it for n days it sends all the keys to the kingdom to those who should receive them.
At this point I've moved almost everything off Google and basically now only use my Gmail account for logins on websites I don't want to give my real email address to and to keep Inactive Account Manager setup to send the necessary info to get into my 1Password account to my brother if I die.
I have a will setup with all my financial details and have set beneficiaries everywhere but this feels like a good backup in case I forget to update it with something or my family has trouble gaining access using other means.
That’s a helpful link! Do you know if google allows access to Gmail once inactivity is triggered? Ideally my contacts could use it to recover access to my password manager.
You have the option to allow that yes. When you add people to be contacted you're able to granularly decide what parts of your google account they get access to and can optionally add a personal message as well.
