How to Enable 2FA on Binance
Binance requires 2FA for withdrawals, API key creation, and security changes. The authenticator-app method protects you even if your password and email are compromised — and unlike SMS, it works regardless of phone signal or SIM-swap attacks.
Quick path: Profile → Security → Authenticator App → Manage
Step-by-step: 2FA setup on Binance
- 1
Open Binance security settings
Sign in at https://www.binance.com, hover over your profile icon → 'Security'.
- 2
Enable the Authenticator App method
Find 'Authenticator App' in the list and click 'Manage' → 'Enable'. Binance walks you through a short wizard.

Copy the setup key, then scan the QR
Binance shows a QR code and a setup key. Write the setup key down first — Binance recommends keeping it as a paper backup — then scan the QR with 2FAA.
- 4
Verify ownership
Binance sends verification codes to your email (and phone, if linked). Enter those plus the current 6-digit code from 2FAA.

Done — 2FA now guards withdrawals
Every login from a new device, withdrawal, and security change now asks for the authenticator code.
Generate Binance 2FA codes with 2FAA
You don't need a separate authenticator app. 2FAA is a free, browser-based TOTP generator — your secret never leaves your device, and it works offline as a PWA. The same secret can be used in parallel with Google Authenticator or Authy if you prefer redundancy.
Frequently asked questions
Binance asks for 'Binance/Google Authenticator' — can I use 2FAA?
Yes. That label just means any standard TOTP app. Binance's own app, Google Authenticator, and 2FAA all generate identical codes from the same QR code.
Why does Binance tell me to save the setup key?
The setup key is the TOTP secret itself. If you lose your authenticator device, you can re-add the same key on a new device and your codes keep working — no account recovery needed.
I lost my Binance authenticator and didn't save the key — what now?
Use Binance's 'Security verification unavailable?' flow on the login page to reset 2FA. Expect identity verification (ID + face) and a 24–48 h withdrawal lock after the reset.
Can I keep SMS and authenticator 2FA at the same time?
Yes — Binance supports multiple methods in parallel and lets you choose which to require for which action. Keep the authenticator as your primary; treat SMS as a recovery convenience at most.
