Protect your Zeta account with 2FA

Two-factor keeps your scan history, family members, and payment info safe even if your password leaks.

Setup steps

1. Enable in settings

Go to Settings → Security → Two-Factor. Tap “Turn on 2FA.”

2. Choose method

Select Authenticator App (recommended) or Email OTP. Scan the QR code with your authenticator if chosen.

3. Confirm backup codes

Save the 10 backup codes in a password manager. You’ll need them if you lose device access.

Troubleshooting

Authenticator code not accepted

Check that your phone time is synced automatically. Out-of-sync clocks cause invalid OTPs.

Tip: In Google Authenticator, enable “Time correction for codes.”

Lost phone

Use one of your backup codes when logging in, then disable 2FA from the new device and re-enable it.

Tip: If you lost codes too, email security@zeta.app with ID verification.

Email OTP delayed

Whitelist notifications@zeta.app. Some providers throttle links; request a new code after 60 seconds.

Tip: Consider switching to an authenticator app.
