2026年6月5日を更新しました

2 要素認証 (2FA) は、パスワードが漏洩した場合でも、Binance アカウントを保護します。 iPhone、iPad、または Mac で Authenticator App を使用して Binance 検証コードを生成するには、以下の手順に従ってください。

Download Authenticator App
Download Authenticator App from the App Store on your iPhone, iPad or Mac. It's free and no sign-up is required.
Open Binance security settings
Sign in to Binance, click your profile icon and choose “Security”.
Enable Authenticator App verification
Next to “Authenticator App”, click “Manage” → “Enable”. Binance will guide you through downloading, then show a QR code and setup key.
Scan the QR code with Authenticator App
Open Authenticator App, tap the + button and scan the QR code shown by Binance. If you can't scan it, choose the manual option on Binance and type the setup key into the app instead.
Enter the 6-digit verification code
Type the 6-digit code from Authenticator App back into Binance to confirm the setup. The code refreshes every 30 seconds.
Save your backup codes
If Binance offers backup or recovery codes, download or write them down and store them somewhere safe. They let you regain access if you ever lose your device.
