How to set up or enable two-factor authentication (2FA) for Google Fi
To keep your Google Fi account secure, enable two-factor authentication (2FA). This page explains how Google Fi 2FA works, which methods Google Fi supports, and how to protect and recover your account. The most secure option is an authenticator app: store your Google Fi 2FA codes in MS Authenticator App and generate a fresh 6-digit code every time you sign in.
2FA methods Google Fi supports
- SMS text message
- Phone call
- Authenticator app (TOTP)
- Proprietary app
- Security key (U2F / WebAuthn)
An authenticator app (TOTP) is the sweet spot: free, offline, and not vulnerable to SIM-swap attacks like SMS.
