The Biometric Illusion

You think your fingerprint is the key. It's not. It's a convenience shortcut that Apple, Google, and Samsung disable the moment they suspect something is wrong.

Apple disables FaceID/TouchID after: • 48 hours of device inactivity • A device restart • 5 failed biometric attempts • After a remote lock command

Once disabled, the device demands the alphanumeric passcode. The one you set 3 years ago. The one you've never typed because biometrics always worked. The one your spouse has never seen.

Your family is now locked out of your photos, your notes, your authenticator app, your email — and every crypto exchange account behind that email's 2FA.

The Cascade Failure

It starts with the phone. But it doesn't end there.

Phone locked → Can't access email → Can't reset exchange passwords → Can't access 2FA codes → Can't move crypto → Can't access authenticator backup codes → Can't access anything.

One locked phone creates a cascade of inaccessible accounts that can take months — or forever — to resolve. Apple won't unlock it for your widow. Google won't either. Coinbase will ask for a death certificate and maybe respond in 6-12 months.

Your family is grieving AND playing tech support. That's not a legacy.

The Fix: Separate Biometrics from Inheritance

Stop relying on biometrics for inheritance.

1. Document your device passcodes — every phone, tablet, laptop. Store them in ZeroLatch.
2. Export your 2FA backup codes — every authenticator app has them. Store them in ZeroLatch.
3. Set a dead man's switch — if you don't check in for 30 days, your spouse gets: • Device passcodes • 2FA backup codes • Exchange credentials • Email access instructions

Biometrics are for the living. ZeroLatch is for when you're not.
