HeirVault is not a day-to-day password manager. Use it to hand off the master key and context so someone can open the vault that already holds your logins.
Continue using 1Password, Bitwarden, Proton Pass, or another manager for everyday sign-in. HeirVault does not replace autofill. It solves the inheritance gap those tools leave when nobody else can open the vault.
Store the master password, emergency kit or Secret Key PDF, and any 2FA backup codes needed to open that manager. Add a short note: which manager you use, the account email, and which five accounts matter first (primary email, banking, insurance, phone carrier, attorney portal).
You can import CSV exports into HeirVault for release handoff. Parsing stays in your browser and entries encrypt before save. Keep the live day-to-day vault in your password manager so you are not maintaining two active copies of every login.
Designate who should receive the password-manager file. Tell them the service name and that a claim email may arrive someday. Do not share the master password early unless you intend them to have access now.
