Biometrics do not replace recovery planning

A fingerprint or face unlock is one authentication method, not a complete estate plan. Devices can require a passcode after a restart or other security condition. The precise rules depend on the device and software, so use the manufacturer’s current documentation rather than assuming a biometric option will always be available.

Identify which accounts depend on the device, which recovery methods exist and who is authorised to use them. Preserve a separate copy of important photos and records instead of making one phone the only usable archive.

Avoid one device becoming the only recovery route

Email, authentication apps and password-manager access can share dependencies on a phone. If that phone is unavailable, an independent recovery method may be needed. Document the provider’s approved route rather than guessing at a bypass or promising a response time.

Apple’s Legacy Contact guidance explains the selected-data access process and its limits. It does not include iCloud Keychain passwords or passkeys. Ask the intended person to locate the required instructions using harmless material; do not assume that receiving a device also grants authority over every account on it.

Separate device recovery from inheritance

Do not assume biometrics will remain available or that a device passcode grants legal authority. Configure Apple Legacy Contact or the relevant platform process, preserve independent photo and account backups, and document where provider recovery factors are held.

A ZeroLatch delivery can hold a scoped device inventory or recovery map after its supported timeline. Avoid combining every device passcode, 2FA backup code, exchange credential and email secret in one package. Test with a spare or sample device and keep urgent medical information on the recognised lock-screen mechanism.
