Probably a boring answer but I know my grandmother’s credit card information. I live with and help take care of her, so she doesn’t mind sharing it with me. Not like I’m planning to do anything nefarious, but I guess technically it could ruin her financially.
BitWarden does have something similar via “backup access” and “organisation” vaults. I’ve not looked at setting up either, yet.
Bitwarden is kinda insane for the amount of features it offers. I recently found that you can create an organisation and add family members, and have it set up so that you can reset their password if they’ve forgotten it, while still securely encrypting the passwords. This was a really cool feature that I didn’t know was even possible.
