Step-by-Step Guide

1

Keep the phone active and charged

Microsoft Authenticator codes are on the phone. Do not reset or erase it. The phone is the key to all accounts using this app for 2FA.

2

Check for cloud backup

Microsoft Authenticator can back up credentials to iCloud (iOS) or a Microsoft account (Android). If backup was enabled, credentials can be restored to a new device.

3

Handle work/employer accounts separately

If Microsoft Authenticator includes work accounts (Entra ID/Azure AD), contact the deceased's employer IT department for those accounts.

4

Contact platforms for 2FA removal

For each locked account, contact the platform's support with a death certificate to request 2FA removal or alternative verification.

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.
