Yes, you can enable both. Passkey and authenticator app are parallel options in Binance's two-factor authentication (2FA) policy. They are not either-or choices. They are designed for different goals: one focuses on anti-phishing and convenience, while the other is a classic dynamic code tool.

Can They Be Enabled at the Same Time? What Enabled Together Means
Binance supports a custom two-factor identity verification policy. You can choose from passkey, email code, authenticator app, and SMS, and decide which method is triggered for different actions. You can turn on both passkey and authenticator app and assign them to different operation scenarios.
For example: use passkey for login (face or fingerprint), and require the authenticator app's 6-digit code plus email verification for withdrawals. These two verification methods do not conflict and can coexist in the same account security policy.
Risk Comparison: They Protect Against Different Threats
| Comparison | Passkey | Authenticator App |
|---|---|---|
| Technical principle | Public-key encryption; private key stored locally on device | Time-based one-time password; seed stored on device |
| Anti-phishing effect | Strong; bound to a specific domain, so phishing sites cannot use it | Weak; if you enter the code on a phishing site, it can be stolen |
| SIM swap protection | Strong; not tied to phone number | Not affected; it does not rely on a phone number |
| Device replacement cost | Low; supports cross-device sync through iCloud Keychain or Google Password Manager | Medium; needs manual seed migration or cloud backup recovery |
| Main attack surface | Device itself being physically obtained or unlocked | Seed stolen by malware, or user tricked into giving dynamic code through phishing |
| Experience | Passwordless; one-tap login with face or fingerprint | Need to open the app and copy the 6-digit code |
Practical Daily Use Tips
- Enable passkey as your main login method first. It is more phishing-resistant than SMS and email codes, and you do not need to open an app to copy a code every time.
- Keep the authenticator app as a backup or extra layer. For example, when withdrawing large funds, combine passkey and authenticator app for stronger protection.
- Do not over-rely on a single verification method. If you only enable passkey and lose your device or biometrics fail, account recovery will be difficult. Keeping an authenticator app as a fallback is safer.

How to Check If Both Are Enabled
Go to Binance App → [Account] → [Security] → [Two-Factor Authentication Policy] and check the list of enabled verification methods. If passkey and authenticator app both show as 'Enabled', then you have successfully turned on both verification methods at the same time.
