Two-factor authentication (2FA) asks for a second proof at sign-in, besides your password. The proof can be a text-message code or an authenticator app code. Face or fingerprint unlock opens the phone or the app and is a separate feature. Which betting apps describe 2FA is Not checked here.

## What it is

Your password is one proof. A code sent to your phone, or generated by an app, is a second proof. Sign-in needs both.

The aim is simple: a stolen password alone does not open your account.

**In short:** Two different proofs, not two passwords.

## 2FA and phone biometrics

Face or fingerprint unlock proves you to your phone or to an app on that phone. Whether an operator counts it as a second factor is stated in its help pages: Not checked.

Apple and Google both publish two-step sign-in features for their own accounts. Their help pages are the source for how they work and must be re-read before publication: Not checked.

**In short:** Biometrics unlock a device; 2FA adds a second proof at sign-in.

## What operators document
