Same, I want with another layer of security. Maybe an OTP (one time password) whenever you make a transaction or another 2FA. But of course, we need a wallet that is portable and flexible. A wallet that you can activate a program that a member of your family takeover your crypto assets whenever it happen to you.
I like the idea of having a family take over the crypto assets on whatever bad things happen to you as an accident, death or other valid incidents.
This is possible but it has many security flaws maybe KYC is required on this kind of feature.
I really don't know if there's a wallet that has this kind of feature, If you know one please share it to me

Using 2FA have make an exchange and your wallet very secure and keep holding your assets although for long term keep safety, but with crypto you have'tn private how much bitcoin do you have and keep give information to your family which one exchange do you save your assets and give them your bitcoin wallet data, when you got something bad your family can access to your bitcoin wallet.
