Password managers and security tools are designed to be impenetrable fortresses, protecting your most sensitive information with military-grade encryption. This creates a paradox in legacy planning: the very security measures that protect you in life can permanently lock out your loved ones after death unless you plan appropriately.

Your password manager likely contains credentials for dozens or hundreds of accounts, including financial institutions, email accounts, and critical services. Without access to this vault, your family may be unable to manage your digital estate, access important accounts, or even complete basic administrative tasks after your death.

Critical challenges include physical device required - cannot remotely access registered accounts, yubikey pin required for fido2/passwordless - unknown pin locks device, and most users own only one yubikey (no backup key registered). These security layers protect against unauthorized access but can also prevent legitimate access by authorized family members and estate executors.

DeathNote helps you securely document master passwords, recovery keys, 2FA backup codes, and hardware security device PINs. You can provide step-by-step instructions for accessing your password vault while ensuring this information remains encrypted and protected until properly verified death triggers delivery to your designated contacts.

Consider creating a layered access plan: emergency contacts who can access critical accounts immediately, trusted executors who receive full vault access, and detailed documentation of what's stored where. This planning ensures security during life while enabling access when needed.

Multi-protocol authentication (FIDO2, U2F, OTP, Smart Card, OpenPGP), passwordless login, 2FA for high-security accounts

Supports 100+ services: Google, Microsoft, Apple, GitHub, Coinbase, Kraken, Dropbox, password managers, SSH

Physical USB device (YubiKey 5 Series, YubiKey Bio, Security Key Series), device PINs, OTP slots, FIDO2 credentials, smart card certificates

YubiKey's #1 inheritance failure: Users buy one key, not two. Single key = single point of failure. YubiKeys cannot be cloned. ALWAYS register 2 keys per account.

YubiKey 5 and YubiKey Bio require PIN for FIDO2/passwordless authentication. PIN protects key if stolen but blocks family if unknown. Secure storage critical.
