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.
