I am a big fan of Bitwarden's emergency access system and use it for my estate automation. Please let me know if there is a flaw in my setup or if you have a better idea/approach.
In short: Bitwarden allows you to set up a situation in which another Bitwarden account (e.g. your partner or child) gains access to your passwords. The other account will then have to explicitly demand access and you set a time (e.g. 2 weeks) in which you can revoke this in your account (you'll receive a big notification, impossible to accidentally miss). If you don't revoke it, the other account will have full access.
How I use this: I wrote a manual for my wife that is stored in our physical vault in case I die or become mentally incompetent. It explains how she can log in to a secondary Bitwarden account that i prepared and ask for emergency access to my account. After 2 weeks, she'll get access to everything (bank accounts, assets, social media etc.). I made it so it's pretty much impossible to access anything with just the Bitwarden account or just the paper. For example are all Passwords in Bitwarden incomplete and the missing characters are on the paper.
I think this will make it much easier for my wife to get along if I'm gone, especially since the bureaucracy is much slower and more complex to get her there, and some companies will simply refuse to give account access to those left behind, even after all proof has been presented.
Do you see any flaw here? Of course if one component is missing (e.g. Bitwarden goes down right with me or the paper gets lost, stolen or damaged), this will not work, but that's what makes it secure. I haven't found any better way of doing this. The only thing that comes close is https://superbacked.com, but here someone could get access to enough pieces and compromise me without me knowing.
I also wonder why no other password manager offers such solution and instead follows an "all or nothing" approach when it comes to emergency access. Bitwarden is not perfect, but I'd keep using it for this single reason if I had to.
Thanks for reading all this, I'm looking forward to your replies!
