Two-Factor Authentication Devices

Many accounts require a second factor (2FA) beyond the password — usually a code from a phone app or a physical key. Here's how to handle that.

Authenticator App

App Used[e.g., Google Authenticator, Authy, Microsoft Authenticator]
On Which Device[e.g., Steve's iPhone, also on iPad]
Backup Method[Does the app sync to cloud? Is there a backup device?]

Physical Security Keys

Key TypeLocationAccounts It's Used For
[e.g., YubiKey][e.g., On keychain, in safe][e.g., Google, GitHub, Bitwarden]
[Backup key][Location][Same accounts]

SMS / Phone-Based 2FA

[Which accounts use text message codes? These will go to Steve's phone — you'll need access to that phone number. See "Phone & Cell Plan" for how to transfer or access the number.]

How to Access Steve's Phone

Phone Model[Model]
PIN / Passcode[Where to find it — e.g., password manager, written in safe]
Biometric[Face ID / fingerprint — won't work for others, use PIN]

If You Can't Get 2FA Codes

Most services have a recovery process. Look for "Recovery Codes" on the next page, or contact the service's support with a death certificate — most major services (Google, Apple, Microsoft, etc.) have a deceased user process.
