Step-by-Step Guide
Find all physical YubiKeys
Search keychains, desk drawers, safes, laptop bags, and offices for YubiKey devices. They are small USB or NFC devices. There may be multiple keys.
Identify which accounts use the YubiKey
Check the deceased's records for which accounts were protected by YubiKey. Common ones include Google, Microsoft, GitHub, crypto exchanges, and banking.
Look for backup keys
Best practice is to register a backup YubiKey. Check for a second key stored in a safe or different location. The backup key works for the same accounts.
Contact platforms if keys are lost
If no YubiKey can be found, contact each platform's support with a death certificate. Some platforms allow removing hardware key requirements with identity verification.
Check for backup codes
Many platforms provide one-time backup codes when a hardware key is registered. Check for printed codes in safes or filing cabinets.

What is 2FA?
Two-factor authentication (2FA) is the single biggest barrier families face when accessing accounts after death. If 2FA is enabled on an account and nobody has the authenticator device or backup codes, the account may be permanently inaccessible.
Google Authenticator
Open Google Authenticator → tap your profile icon → turn on sync. This backs up your 2FA codes to your Google account so they survive phone loss.
Authy
Settings → Devices → Allow multi-device. This lets you add Authy to multiple phones or tablets. If multi-device is off and the phone is lost, recovery is extremely difficult.
