BYDFi Security Center Upgrade Notice

Dear User,

To further enhance the protection of user assets and accounts, BYDFi is officially launching Security Center 2.0, delivering a more comprehensive and flexible security experience.

🔑 Key Upgrade Highlights

1. Biometric Authentication

• On the App, Face/Touch ID is now supported for login, withdrawals, internal transfers, and key account actions, improving both convenience and security. (PC support will be available in future versions)

2. Multi-device Passkey

• One account can now bind multiple devices with passkeys (Face/Touch ID), solving the issue of frequent switching between devices.

3. Enhanced Withdrawal Protection

• Withdrawals and internal transfers now require mandatory binding of Google Authenticator (GA).
• New cross-device withdrawal confirmation: confirm Web withdrawals via App QR scan.
• Added a "New address 24-hour withdrawal restriction" prompt for clearer risk alerts.

4. Flexible 2FA Verification

• During login and operations, users can freely switch between bound verification methods (GA, email, phone) for a smoother experience.

5. Account & Device Management

• New option to modify the bound email; withdrawals and transfers will be restricted within 24 hours after modification.
• The App now allows users to view the last 50 login records and remotely log out from other active devices.
• For PC QR-code logins, the App will display detailed login information (IP, location, device model) for confirmation.

6. Security Logs & Instant Alerts

• Users can review up to one month of security operation records (e.g., password or verification method changes).
• Unified verification code templates and new real-time abnormal login alerts provide better protection.

We strongly recommend all users review and update their security settings to ensure maximum protection. BYDFi will continue to strengthen security measures and provide you with a safe and reliable trading environment.
