I can definitely tell you I’m comfortable with that.

If family doesn’t know I’m dead in 3 days, they ain’t family.

The likelihood that I die, and my loved ones decide to just turn off the server while knowing it’s where the Vaultwarden software lives, before they get access to said Vaultwarden, is very very slim.

Self host whatever you want. Even Deadman switches.

The key is informing your loved ones the requirements for the switch. Just like if they don’t know to request access in other Deadman switches.

You can self host Vaultwarden, which is essentially self managed Bitwarden.

And the feature can be setup fairly easily.
